Unlike other water splitters that use precious-metal catalysts the electrodes in the Stanford device are made of inexpensive and abundant nickel
professor at Stanford university. his is the first time anyone has used non-precious metal catalysts to split water at a voltage that low.
But scientists have yet to develop an affordable active water splitter with catalysts capable of working at industrial scales. t s been a constant pursuit for decades to make low-cost electrocatalysts with high activity
Professor Shu Kobayashi's group at the Graduate school of Science has developed highly active immobilized catalysts (heterogeneous catalysts)
and demonstrated simple and highly efficient synthesis of (R)- and (S)- rolipram by an eight-step continuous flow reaction using multiple column reactors containing the immobilized catalysts.
Professor Kobayashi's application of flow chemistry techniques to the production of fine chemicals using heterogeneous catalysts has resulted in simple method to synthesize (R)
and without purification of products from catalysts. Professor Kobayashi says"This new technology can be applied to not only other gamma aminobutyric-acids acids and medicines but also various chemicals such as flavors, agricultural chemicals,

As well as offering new opportunities for industry, it will stimulate the search for even better basic catalysts
Catalysts come in multiple forms including: acids, solid metal nanoparticles, and large protein molecules or enzymes in human bodies.
Ninety percent of industrially important chemicals are made using catalysts. It is a major field in applied science;
This study opens a new way for designing metal-based catalysts with complexities, for example, geometry and composition, promoters and poisons, defects,
#Inexpensive new carbon-based catalysts can be tuned fine The new catalyst is based carbon, made of graphite with additional compounds bonded to the edges of two-dimensional sheets of graphene that make up the material.
Jose-Luis Olivares/MIT) Catalysts enhance the rate of a chemical reaction but are consumed not in the process.
By finding a way to make this material tunable in the same ways as molecular catalysts
In addition to their possible uses in fuel cells, such new catalysts could also be useful for enhancing chemical reactions,
