Thanks to my wife for her patience with me spending many hours working on the book series through the nights and over weekends.

The assistance of my son Marc Philip related to the complex and large computer files with many sophisticated scientific figures is also greatly appreciated.

Series Editor Preface

Since years, nanoscience and nanotechnology have become particularly an important technology areas worldwide. As a result, there are many universities that offer courses as well as degrees in nanotechnology. Many governments including European institutions and research agencies have vast nanotechnology programmes and many companies file nanotechnology-related patents to protect their innovations. In short, nanoscience is a hot topic!

Nanoscience started in the physics field with electronics as a forerunner, quickly followed by the chemical and pharmacy industries. Today, nanotechnology finds interests in all branches of research and industry worldwide. In addition, governments and consumers are also keen to follow the developments, particularly from a safety and security point of view.

This books series fills the gap between books that are available on various specific topics and the encyclopedias on nanoscience. This well-selected series of books consists of volumes that are all edited by experts in the field from all over the world and assemble top-class contributions. The topical scope of the book is broad, ranging from nanoelectronics and nanocatalysis to nanometrology. Common to all the books in the series is that they represent top-notch research and are highly application-oriented, innovative, and relevant for industry. Finally they collect a valuable source of information on safety aspects for governments, consumer agencies and the society.

The titles of the volumes in the series are as follows:

The book series appeals to a wide range of readers with backgrounds in physics, chemistry, biology, and medicine, from students at universities to scientists at institutes, in industrial companies and government agencies and ministries.

Ever since nanoscience was introduced many years ago, it has greatly changed our lives – and will continue to do so!

Foreword

At present the world is facing enormous problems concerning climate, energy, environment, and food and is waiting for solutions provided by technology, in particular chemistry. Catalysis is the motor for chemical transformations; for technical applications, it is mostly heterogeneous catalysis where the processes occur at the surfaces of solids. Since for a given quantity of material the accessible surface area increases with decreasing particle size, catalyst particles exhibit typically dimensions in the nanometer range, and catalysis has been a nanotechnology already long before this term was introduced. The controlled preparation, stabilization, and characterization of well-defined nanoparticles is hence one of the important tasks of research. The electronic and thereby chemical properties of very small particles may differ considerably from those of the bulk material, leading to altered catalytic properties as shown, for example, by gold and impressively demonstrated in Chapter 2 by Masatake Haruta. An alternative possibility consists in the use of porous bodies, as, for example, offered by the large family of zeolites and related compounds that are widely used in industrial applications.

This book presents a series of contributions from experts of the field reflecting the current state of the art and demonstrating the potential of nanocatalysis for a number of practical applications. It will therefore be of considerable value for those interested in the development of this area.

Foreword

A View from the Ridge: Catalysis in a Modern Society

Today's inspection of bookshelves with catalysis books in a traditional science library or of databases with catalysis review collections shows a pleiad of keywords covering almost every aspect of modern science. A personal selection of keywords in the area of (heterogeneous) catalysis looks as follows:

Thus, it seems that at the end of the 2nd millennium, catalysis research was making effective use of many major advances offered by progress in various areas of science. Catalysis, and in particular heterogeneous catalysis, appeared as a truly multidisciplinary science that was profoundly affecting in a positive way environment and daily activities. In combination with modern materials science, very advanced materials were designed, applicable as catalysts in many petrochemical, chemical, and fine chemical sustainable industrial processes. As a result, catalysis was susceptible for being defined as a mature science.

An overview of the science and technology of heterogeneous catalysis at the end of the 1990s culminated in the publication of an impressive standard work denoted as Handbook of Heterogeneous Catalysis, published by the present science editor (scientific eds. G. Ertl, H. Knözinger, F. Schüth, and J. Weitkamp, 2nd edition). It covered all aspects of heterogeneous catalysis ranging from physical and physicochemical concepts to large-scale process technology.

Although the catalytic community of research scientists usually picks up quickly breakthroughs from other scientific domains, and the scientific literature at the end of previous century already showed clear awareness of the potential use of nanosciences for advancement in (heterogeneous) catalysis, today's revolution caused by nanotechnology in catalysis among many other domains was not fully and explicitly realized.

Nanoheterogeneous Catalysis in a Sustainable Society

In the traditional heterogeneous catalysis of the twentieth century, microsized and microstructured objects of catalyst entities were determining activity and selectivity. Enhanced strength of Brønsted acid sites is encountered in solids with regular microporosity. The deposition of metal clusters on supports gave rise to the concept of structure-sensitive and structure-insensitive reactions, depending on the size, morphology, and surface properties of (noble) metal particles.

The many reviews in the area invariably show that the aim of nanomaterials science in the past few decades has been related to the control of size, shape, structure, morphology, and composition of matter, leading to nanoproducts with a high degree of perfection. Therefore, selective implementation of nanoconcepts into catalyst design and preparation strategies should show significant advances in the design, synthesis, and characterization of catalytic nanomaterials. Obviously, this transfer of concepts will help to settle major standing issues in catalysis for a sustainable society, such as preparation of novel catalyst compositions with enhanced/superior potential for alternative chemicals production and alternative feedstock conversion, for achieving a sustainable energy future, and for environment protection.

Inspection of search results in a science database for the nanocatalysis concept (SciFinder, January 24, 2017) yielded from 2000 onward 472 hits in English written books and reviews. A similar search for specific research papers and patents up to 2000 amounted to only 12 hits, while from 2000 onward a total number of 7001 documents appeared. When the concepts of nanotechnology and catalysis are closely coupled in a similar database search, in total some 5400 reviews show up, of which 536 were published recently, that is, later than 2015.

Many typical topics concerning properties of nanomaterials for biomass conversion, energy, and environmental processing appear, resulting in newly structured materials with unprecedented properties allowing us to achieve hyperselectivity in many catalytic reactions. A personal grasp in the many available topics points to the high potential of nanocatalysts with mono- and multimetal sites, for selective conversion of hydrocarbons and biomass components, newly designed photocatalytic materials in energy (carrier) conversions:

It is understandable that the present editors, given their activity as catalyst researcher and science policy maker, respectively, felt the necessity of bringing this abundant information together in an easily digestible format. I am pleased to be able to express my personal appreciation for this initiative and I am looking forward to get fully acquainted with the detailed content of this new three-volume handbook in catalysis.
