Accelerating or facilitating chemical reactions is pivotal for many conversions and industrial processes. Hydrocarbon cracking in oil refineries, the reduction of nitrogen oxides in car emissions by means of the platinum catalytic converter, the oxidation of hydrogen in fuel cells, biocatalytical enzymatic conversions or ammonia synthesis are only a few examples of how much industry relies on potent catalysts.

Self-healing coating surfaces and tamper-evident security are two of the many benefits that your products can achieve by incorporating microencapsulation more
Metals such as gold or platinum are often used as catalysts. In the catalytic converters of vehicles, for example, platinum nanoparticles convert poisonous carbon monoxide into non-toxic CO2. Because platinum and other catalytically active metals are expensive and rare, the nanoparticles involved ha more
Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process - and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But more
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. State- more
Chemist Xile Hu is awarded the National Latsis Prize 2017, Xile Hu is Professor of Chemistry at the Swiss Federal Institute of Technology in Lausanne (EPFL). He is honored for his impressive scientific career and outstanding research on the fundamental understanding of catalysis. more
ETH Zurich scientists have discovered a new catalyst that allows the easy conversion of natural gas constituents into precursors for the production of fuels or complex chemicals, such as polymers or pharmaceuticals. The new catalyst is extremely stable and results in fewer unwanted by-products. ... more
In a new twist to waste-to-fuel technology, scientists at the Department of Energy’s Oak Ridge National Laboratory have developed an electrochemical process that uses tiny spikes of carbon and copper to turn carbon dioxide, a greenhouse gas, into ethanol. Their finding, which involves nanofabric ... more
While the technique has gained increased popularity in recent times, the principal of in situ reaction monitoring dates back to 1961 when Farenfort introduced a new method of measurement that today is called Attenuated Total Reflectance (ATR). The co more
In contrast to Schwesinger type phosphazene N-superbases the compounds presented herein exhibit even more basicity more
With over 25 years’ experience in the construction of pressure vessels behind it, Berghof is offering an innovative device concept for many types of applications in research and development laboratories. Chemical reactions, which take place under tem more
Volkswagen have been in the news for all the wrong reasons. The company admitted to installing a ‘defeat device’ in millions of cars which made it appear in emissions tests that they emitted far lower levels of particular pollutants than they actually did in normal road conditions. Plenty of article more
How different factors can affect how quickly a reaction happens is a common topic in the chemistry curriculum. This graphic serves as a convenient summary for teachers and students alike of what these different factors are, and how and why they affect the rate of a reaction. However, it’s not only o more
The direct synthesis of copper selenide nanoparticles from the reaction of ditertiarybutyl selenide tBu2Se with copper(ii) trifluoroacetate Cu(TFA)2 under mild conditions is reported. The isolation of a molecular species during the course of this reaction, established as [Cu2(TFA)2(tBu2Se)3], by spe more
MnOx/TiO2 (MnTi) and Nd-modified MnOx/TiO2 (MnNdTi) were prepared via a coprecipitation method. The used samples were obtained by exposing the fresh catalysts to 50 ppm SO2 stream at 210 oC for 3 h and 6 h, respectively. Comparative investigations were performed on the fresh and used catalysts to id more
MFI Zeolites exchanged with various cations have gained a great deal of attention as catalysts. Increase in the ion-exchange capacity of zeolites can improve their catalytic properties by introducing more active sites; however, the ion-exchange capacity of MFI zeolites is limited by maximum aluminum more
Light is a powerful tool to manipulate a vast variety of chemical processes. The use of specific photo-chromic molecules allows chemists to perform reactions in a reversible fashion with a high spatio-temporal resolution. more
For the first time, an efficient catalyst for palladium-catalyzed C–C bonding between aryl chlorides and alkyl lithium compounds has been found. This reaction enables simpler synthesis routes for important products, such as pharmaceuticals, while avoiding much salt waste. more
Photoredox catalysis has developed into a powerful tool for the synthesis of organic compounds with diverse structures. However, the high stability of carbon-chloride bonds has long hampered the use of cheap and readily available chloroalkanes as substrates. more
