Method enables sustainable oxidations related to enzyme reactions
Acetals are important chemical compounds that are used, for example, in the production of certain medical agents. A new method now makes their synthesis easier and more environmentally friendly. Chemists at the University of Bonn have developed and optimized the sustainable catalytic process. ...
New research method answers important questions
Metal surfaces play a role as catalysts for many important applications - from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface. This phenomenon has been known for a long time, but until now it has ...
Lowering the combustion temperature for methane
Reza Shahbazian-Yassar, professor of mechanical and industrial engineering at the University of Illinois Chicago and colleagues facilitated the development of a cutting edge "Swiss Army knife" catalyst made up of 10 different elements - each of which on its own has the ability to reduce the ...
A key to producing green hydrogen more efficiently
A layer as thin as a single atom makes a huge difference: On the surface of an electrode, it doubles the amount of water split in an electrolysis system without increasing the energy requirements. Thus, the ultrathin layer also doubles the amount of hydrogen produced without increasing costs. ...
Easy-to-handle nickel complexes for practical application in nickel catalysis
The use of nickel as a catalyst for the formation of chemical bonds is of great importance to the chemical industry - applications range from the production of fine chemicals to the synthesis of pharmaceuticals, insecticides and pesticides. For the production of nickel complexes, industry has ...
Researchers take key step toward cleaner, more sustainable production of hydrogen
Efficiently mass-producing hydrogen from water is closer to becoming a reality thanks to Oregon State University College of Engineering researchers and collaborators at Cornell University and the Argonne National Laboratory. The scientists used advanced experimental tools to forge a clearer ...
For the first time, researchers have used a novel catalyst process to recycle a type of plastic found in everything from grocery bags and food packaging to toys and electronics into liquid fuels and wax. "Plastics are essential materials for our life because they bring safety and hygiene to our ...
Scientists Use Advanced Methods with Hybrid Functionals for Analysis of Active Sites
Catalysts are indispensable for many technologies. To further improve heterogeneous catalysts, it is required to analyze the complex processes on their surfaces, where the active sites are located. Scientists of Karlsruhe Institute of Technology (KIT), together with colleagues from Spain and ...
Operando X-ray Spectroscopy Brings New Opportunities for Materials and Reaction Diagnostics
For understanding the structure and function of catalysts in action, researchers of Karlsruhe Institute of Technology (KIT), in cooperation with colleagues from the Swiss Light Source SLS of Paul Scherrer Institute (PSI) in Switzerland and the European Synchrotron Radiation Facility (ESRF) in ...
A new type of palladium catalysts based on chitin can be reused over 10 times
Chemists from RUDN University synthesized soluble biopolymers based on chitin from crab shells. Together with palladium, they form effective catalysts for organic reactions, and their nanoparticles can be re-used over ten times. Palladium-based catalysts are used to speed up cross-coupling ...
