Metal hydrides are key intermediates in catalytic proton reduction and dihydrogen oxidation. There is currently much interest in appending proton relays near the metal centre to accelerate catalysis by proton-coupled electron transfer (PCET). However, the elementary PCET steps and the role of the pr...
Metal hydrides Hydrogen compression Energy efficiency Heat utilisation 1. Introduction Metal Hydride (MH) hydrogen compression utilises a reversible heat-driven interaction of a hydride-forming metal, alloy or intermetallic compound with hydrogen gas to form MH and is considered as a promising application...
30–34 kJ mol−1-H2) are promising candidates for hydrogen storage. They were successfully synthesized by reacting carbazole with respective metal hydrides, where the basic Hδ− of metal hydride reacts with the acidic Hδ+-N of carbazole, liberating one equivalent of H2. However, it is ...
More encouragingly, these graphene-based catalysts show favorable HER activity in a wide range of pH values, in contrast to traditional metallic and nanostructured MoS2 electrocatalysts, which are active under either acidic or basic conditions. To design high-performance electrocatalysts for HER, Jiao ...
While the reaction conditions for most reductions are basic, the reduction using Et3SiH is done under acidic conditions (e.g. w/TFA). It finds applications in the reduction of acetals and the reductive removal of alkoxy groups from the anomeric position of sugars. It is also used as a hy...
–Most metal oxides are basic in water.(what are some examples?) –Most nonmetal oxides are acidic in water.(what are some examples?) Metalloids • Have some characteristics of metals, some of nonmetals. • For instance, silicon
The fuel will form metal hydrides and oxides when in contact with water at elevated temperature. However, metal fuel continued to be of interest for use in fast reactors. In the mid-1960s, when the large commercial prototype fast reactors were being designed, metal fuels were largely abandoned...
Noble metals are the effective catalysts for electrochemical systems (fuel cells, metal-air batteries, water splitting) due to their excellent properties, such as primarily low over-potential, outstanding reaction kinetics, and exceptional long-term durability in acidic media [86–88]. Ruthenium (Ru...
