Nanoscale titania takes scientists closer to sustainable hydrogen production Scientists have utilized nano-scale (15-50 nm) titania as photocatalyst to enhance the electrolytic production of hydrogen from biomass-derived compounds. The study was a five-year partnership of Drexel University, Germany's Leibniz Institute for Catalysis, Italy's University of Trieste, Stanford University, Spain's University of Cadiz and University of Pennsylvania.

very mild conditions. The catalysts described in this patent are environmentally friendly, easy to separate and to recover, and can be reused in subsequent reactions.

Catalytic conversion of carbohydrates into 5-hydroxymethylfurfural This patent describes catalysts and catalytic processes for efficient conversion of carbohydrates into 5-hydroxymethylfurfural (HMF). These catalysts exhibit good activity and high selectivity for HMF preparation from saccharides. The catalysts are stable in aqueous systems, which make them very attractive for HMF production. High HMF yield was obtained even under

Catalytic oxidation of dimethyl ether

BOOKSHELF Nanocatalysis in Ionic Liquids

Dimethyl ether (DME) has been studied for a decade as a fuel for portable fuel cell power sources. A composition for oxidizing dimethyl ether includes an alloy supported on carbon, the alloy being of platinum, ruthenium, and palladium. A process for oxidizing dimethyl ether involves exposing dimethyl ether to a carbon-supported alloy of platinum, ruthenium, and palladium under conditions sufficient to electrochemically oxidize the dimethyl ether.

This is the first text to review the state-ofthe-art of nanocatalysis in ionic liquids. The first half of the book describes the different classes of metal nanoparticles as well as their synthesis in ionic liquids. The second half focuses on such emerging issues as the application of such systems to energy and biomass conversion and gas-to-liquid / liquid-to-gas processes.

reaction happening together with the faradaic reaction.

Method for converting methane to methanol at low temperatures Gas Technology Institute in the US has been granted Patent No WO/2015/ 069352 (Publication date: 14 May 2015) For a low temperature methane-tomethanol conversion process. The method uses a reactor containing cathode, anode, a membrane separator between the cathode and anode, a hydrogen-recovery catalyst at the cathode, and a metal oxide catalyst at the anode. It can transform methane to methanol at a rate beyond the theoretical faradaic rate through the electrochemical

This book focuses on the mechanism of enantioselectivity in asymmetric catalysis, rather than asymmetric catalysis from the synthetic view. It reviews experimentally and computationally supported mechanisms, and highlights the pitfalls of pursuing so-called "plausible'' or "accepted'' mechanisms that often lead to wrong conclusions. It examines in detail the physico-chemical aspects of enantioselective catalysis and draws parallels to enzymatic catalysis in biochemistry. I. Gridnev and P. A.

Deactivation of Heavy Oil Hydroprocessing Catalysts This text provides a rigorous examination of the physical and chemical properties of heavy oils and hydroprocessing catalysts; the mechanisms of fixed-bed, and slurry hydroprocessing catalyst deactivation; hydroprocessing catalyst characterization using a variety of techniques and reaction conditions; and laboratory and commercial information for model validations. The author outlines how to develop correlations and models for a variety of reaction scales and provides step-by-step descriptions and detailed experimental data. J.
