Enzyme system for the hydrogen industry - Sonnenseite - Ökologische Kommunikation mit Franz Alt

14.05.2021 Enzyme system for the hydrogen industry An enzyme could make a dream come true for the energy industry: It can efficiently produce hydrogen using electricity and can also generate electricity from hydrogen. The enzyme is protected by embedding it in a polymer. An international research team with significant participation of scientists from Technical University of Munich (TUM) has presented the system in the renowned science journal Nature Catalysis. Fuel cells turn hydrogen into electricity, while electrolysers use electricity to split water to produce hydrogen. Both need the rare and thus expensive precious metal platinum as a catalyst. Nature has created a different solution: Enzymes, referred to as hydrogenases. They catalyze the conversion of hydrogen very quickly and almost without energy loss.

Understanding catalytic couplings: not all synergies are simple

 E-Mail Credit: Credit: Craig S. Day (ICIQ) Negishi cross-coupling reactions have been widely used to form C-C bonds since the 1970s and are often perceived as the result of two metals (i.e zinc and palladium/nickel) working in synergy. But like all relationships, there is more under the surface than what we first expected. PhD student Craig Day and Dr. Rosie Somerville from the Martin group at ICIQ have delved into the Negishi cross-coupling of aryl esters using nickel catalysis to understand how this reaction works at the molecular level and how to improve it. The results have been published in
