The dehydrogenation of unactivated alkanes is an important transformation both in industrial and biological systems. Recent efforts towards this reaction have revolved around high temperature, organometallic C–H activation by noble metal catalysts that
Metallaphotocatalysis provides access to distinct activation modes, which are complementary to those traditionally used in the field of transition metal catalysis, thereby enabling reaction development through entirely new mechanistic paradigms. This Review discusses key advances in the field of metalla...
SCR technology is a reaction at use of the denitration catalyst at a certain temperature (270-400ºC), that NOX in the flue gas mixed with NH3 from the reducing agent supply system after the occurrence of the selective catalytic reduction reaction of nitrogen and wat...
Electrocatalytic oxygen evolution reaction (OER) has been recognized as the bottleneck of overall water splitting, which is a promising approach for sustainable production of H2. Transition metal (TM) hydroxides are the most conventional and classical non-noble metal-based electrocatalysts for OER, ...
Metal-organic frameworks (MOFs) have exhibited enormous potential to be an effective contender for energy conversion (EC) process. Highly organized and adjustable compositions ofMOFassisted to emerge as desirable functional platforms for electrocatalytic processes like thehydrogen evolution reaction(HER),...

Metal oxide catalysts are widely used in the catalytic reaction of oxidation–reduction mechanism; most of the oxides of main group elements are used in the catalytic reaction of acid–base mechanism (such as solid acid catalyst), including oxidation, dehydrogenation, hydrogenation, oxidative dehydrogen...
Base metals are used in jewelry and industry. Here is the explanation of what a base metal is, along with several examples.
