Many processes in the chemical industry use transition metal catalysts, which speed up a reaction without being consumed themselves. A good catalyst will have both high activity (giving fast reactions] and high selectivity (producing few byproducts). Heterogeneous catalysts [Fig I(a)) - solids ...

Most of the studies performed to date in the field of electrochemical synthesis (heterogeneous catalysis) of NH3used similar catalysts (a few different transition metals and Li) in aqueous, non-aqueous, and molten-salt electrolytes with limited or no success (Andersen et al., 2019). New theoret...
Despite of the fact that there are increasing methods to determine compounds such as H2O2 or glycerol, the combination of modified materials has been proved to facilitate the determination of trace metals. The good example is the use of bismuth, polystyrene sulfonate (PSS), and carbon nanopowder...
Among these semiconductors, some metal oxides, for instance, stannic oxide, titanium oxide, cuprous oxide, and vanadium pentoxide are the most important base materials in industry for gas sensors, transistors, and electrode material as well as catalysts. There has been extensive research into ...
Additional studies are essential to recognize factors that donate to this increased risk.Transition steel dichalcogenides (TMDs) have several advantages, such as for instance large conductivity, steady structure, and low cost, making them encouraging catalysts for co2 electroreduction. However, the high ...

Metallocene catalysts for preparing metallocene-catalyzed polyolefins are chiral or achiral transition metal compounds of the formula M1Lx. The transition metal compound M1Lx contains at least one central metal atom M1 to which at least one π-ligand, e.g. a cyclopentadienyl ligand, is bound. In...
SCR catalysts in coal power plants make use of tungsten oxide. In Summary Tungsten is a critical metal in multiple industries. Beneficial properties such as the extremely high melting point and good tensile strength of tungsten makes it an ideal choice for many applications which require high ...
(~91% per cm), making them uniquely valuable as high-performance insulators, supports for chemical sensors and catalysts, and particle detectors. Some aerogels, such as aerogels made of carbon, metals, and carbon nanotubes, also exhibit good electrical conductivity, making them ideal substrates for...
