Gold catalysts have been shown to have superior activities for oxidation reactions, especially at low temperature, compared to other metal-based catalysts. But the high price of gold makes it necessary to develop Au catalysts with ever-higher activities, reducing the amount of Au needed. A promising step in this direction is a new type of catalyst developed by Professor Naoki Toshima and his research group...

For the first time, an organic compound has been synthesized from water, carbon dioxide and sunlight — without any other external energy or reagents. The achievement, which was demonstrated by researchers at Toyota Central Research and Development Laboratories, Inc. (Toyota CRDL; Aichi Prefecture, Japan; www., a subsidiary of Toyota Motor Corp., is...
November 1, 2011
The Fine Chemicals div. of Takasago International Corp. (Tokyo, Japan; has commercialized Deneb: Oxo-Tethered Ruthenium (II) Complex, which shows higher catalytic activities compared to conventional RuCl (arene)(N-sulfonylated diamine) catalyst systems. The higher activity enables a reduction in...
November 1, 2011
Base-catalyzed decomposition (BCD) is a commercially used process developed in the early 1990s by the U.S. Environmental Protection Agency (EPA; Washington, D.C.) for the destruction of persistent organic pollutants (POPs). It has been used as an...

A technique that improves the efficiency of ethanol plants by lowering the cost of dewatering the byproduct stillage (a slurry of corn solids and water) from the fermentation process has been developed by scientists at the U.S. Department of Agriculture’s (USDA) Eastern Regional Research Center (Wyndmoor, Pa.; The process has been demonstrated at full scale in a commercial plant...
October 1, 2011
Professor Yuki Taniguchi at the Chemicals Research Institute, Tokyo Institute of Technology (Japan, has developed a new catalyst system that decomposes volatile organic compounds (VOCs) at lower temperatures than that required by conventional catalysts. The SILP (supported ionic liquid phase) catalyst is composed of silica gel impregnated with an ionic...

The Fine Chemicals Div. of Takasago International Corp. (Takasago; Tokyo, Japan; has commercialized a new, highly efficient asymmetric hydrogenation catalyst for producing chiral alcohols — key chemicals for the production of pharmaceuticals, fragrances and agrochemicals. The ruthenium-complex catalyst is tradenamed RUCY after its molecular structure, ruthenabicycle...
June 1, 2011
A research team from Los Alamos National Laboratory (Los Alamos, N.M.; has developed a novel catalyst for the cathode of a fuel cell that avoids using expensive ($1,800/oz.) platinum metal. The cathode catalyst...
June 1, 2011
A team from CSIRO Materials Science and Engineering (Melbourne, Australia; has developed a new technique for growing smart materials known as metal-organic frameworks (MOFs), which can be used in pollution control, or as catalysts, or for transporting drugs in the human body. MOFs are well-ordered ultra-porous crystals that form multi-dimensional structures with huge surface areas. One gram...
June 1, 2011
A team led by Rice University (Houston; researcher Michael Deem has assembled a database of 2.6 million possible unique zeolites — porous silicate minerals often used as catalysts or molecular sieves. The database of potential structures...
May 1, 2011
Scientists from the National Institute of Advanced Industrial Science and Technology (AIST; Tsukuba, Japan;, in collaboration with Tokyo University of Science and Panchakot Mahavidyalaya University, have demonstrated that a nickel-complex-type organic nanotube (Ni-ONT), developed by AIST, can catalyze oxidation reactions for producing industrial chemicals. For example, the researchers have...
March 1, 2011
Tokyo Chemical Industry Co. (TCI; Tokyo; is planning full-scale production of a new palladium-complex catalyst, trade-named SingaCycle-E1, for performing Heck-Mizoroki carbon-carbon coupling reactions and the Suzuki-Miyaura cross-coupling reaction — both reactions of importance for producing pharmaceuticals. TCI says SingaCycle-E1 offers enhanced activity and improved stability...
May 1, 2009
Researchers at United Environment & Energy (UE&E; Horseheads, N.Y.) have developed a catalyst for the efficient conversion of algae to biodiesel. The mixed-metal oxide catalyst (comprised of metals that are resistant to corrosion yet reactive) facilitates the transesterification of algae oil and methanol. The mechanism for the reaction over the solid...
May 1, 2009
A new procedure for making uniform, metallic nanoparticles has been developed by the research group of Kousuke Mori, an associate professor at Osaka University (, with support from New Energy and Industrial Technology Development Organization (NEDO; Kawasaki, both Japan). The photo-assisted process, which uses...
May 1, 2009
Salts of alkaline-earth metals have been shown to catalyze reactions for the selective formation of carbon-carbon bonds, by chemistry professor Shu Kobayashi and colleagues at the University of Tokyo ( The research, supported by the Japan Science and Technology Agency (Tokyo), promises to deliver alternatives to conventional catalysts that contain toxic, scarce and expensive...
