Designing Catalysts for Tomorrow’s Environmentally Benign Processes

After first recalling some of the key challenges involved in meeting the demands for energy and chemicals by 2050, brief accounts are given of (a) the present scene in water oxidation photocatalysis with parti...

Can a Single Atom Serve as the Active Site in Some Heterogeneous Catalysts?

We examine a number of distinct situations relating to heterogeneous catalysts where either a single atom (or ion), or a very small cluster of atoms functions as the locus of chemical turnover in various disti...

Mono-, Bi- and Multifunctional Single-Sites: Exploring the Interface Between Heterogeneous and Homogeneous Catalysis

This mini-review contrasts the characteristics of traditional heterogeneous (solid) catalysts with those of homogeneous ones: the nature of the active sites in each case is very different, a fact well illustra...

A General Strategy for the Design of New Solid Catalysts for Environmentally Benign Conversions

After first outlining in qualitative terms progress made in predicting and modelling solids in general, a brief account is given of the substantial progress made in enumerating hypothetical open structures bas...

How Far is the Concept of Isolated Active Sites Valid in Solid Catalysts?

Oxide catalysts that have open structures and contain cations exhibiting usually just one or a few oxidation states, and those that are close-packed and contain transition metal ions in many different oxidatio...

The advantages and future potential of single-site heterogeneous catalysts

Using open-structure (nanoporous) solids, advantage may be taken of single-site catalytically active centres to effect an enormous range of conversions of organic compounds where regio-selectivity and shape-se...

The tortuous tale of the catalytically active site

The emergence of the concept of the active site in heterogeneous catalysts is traced from the early, tentative view of H.S. Taylor in 1925 to the structurally well-defined active site (at αTiCl₃ prismatic faces) ...

A New Approach to the Design of Heterogeneous Single-Site Enantioselective Catalysts

We analyze the merits of an approach to the design of enantioselective catalysts that relies on constraining an anchored organometallic complex at the inner walls of mesoporous silica. Two distinct metal cente...

The Electron Microscope Is an Indispensable Instrument for the Characterisation of Catalysts

No other single instrument rivals the electron microscope in the wealth of structural (atomic, nanoscopic, mesoscopic and microscopic), topographic and electronic information that it provides in the characteri...
