Normally, only the ultraviolet (higher energy) component of the solar spectrum is usable for the photo-catalytic electrolysis of water into hydrogen and oxygen, which takes place in photochemical cells with an anode made of single-crystalline, rutile-type titanium oxide and a platinum electrode. Now, water can be photolyzed into H2 and O2...

Researchers at Oxford Catalysts Ltd. (Oxford, U.K.; edlinks.che.com/7372-534) have shown that the method of preparation — rather than the identity or combination of metals used — has the greatest influence on the performance of hydrodesulfurization (HDS) catalysts. The results of laboratory trials, presented at the annual ACS meeting last month (New Orleans, La.; April...

  While it may be one of the oldest chemical processes known to mankind, fermentation is getting a high-tech face lift as industrial biotech firms put a fresh spin on the age-old technology in an effort to develop advanced products in a more environmentally friendly and less costly way. "The technology is generally the same — using microbial systems and metabolic fermentation — but by...

As long as the chemical process industries (CPI) have existed, catalysts have been backstage supporting, if not leading, their progress. And, as much of the chemical industry’s current research efforts center around producing cleaner products, such as transportation fuels and energy sources in a greener way, the same can be said about catalyst development. Certainly, a major reason for the clean and...
