The present invention relates to 'compound metal oxide and nitride catalyst for low-temperature selective catalytic reduction of ammonia' and pertains to the field of catalysts. In A-B-C compound metal oxide, A is a or multiple kinds of lanthanide series metals, B is a or multiple kinds of...
1. A process for alkane ammoxidation to unsaturated carboxylic acids or nitriles comprising: i. reacting an alkane with oxygen, oxygen and ammonia, or an oxygen and ammonia containing gas in the presence of an oxidation catalyst to yield a product comprising at least one unsaturated carboxylic ...
3. FORMATION AND REACTIVITY OF ADSORBED OXYGEN OVER α-FERRIC OXIDE Gold (Au) nanoparticles supported on reducible oxides such as TiO2 demonstrate exceptional catalytic activity for a wide range of gas phase oxidation reactions such as CO oxidation, olefin epoxidation, and water gas shift catalysis....
Since IrO2is regarded as the most promising catalyst for acidic OER, the OER performance of 1T-IrO2deserves deep evaluation15,16,17. The OER performances of IrO2with rutile phase (Rutile-IrO2) and the two reference electrocatalysts: C-IrO2and commercial-Ir/C (C-Ir/C) were also measured...
Developing metal-free, carbon-based catalysts to replace platinum-based catalysts for oxygen reduction reactions (ORRs) is an emerging area of research. In
Mg(NO3)2 and Ni(NO3)2 was mixed with an aq. KOH soln. at room temp. to pH 11, stirred for 1 h, filtered, washed with ammonia water, dried at 130°, fired at 550° in air to give Mg Ni oxide, which was size-reduced, sieved, and dissolved at 40° in ...
Electrocatalysts are crucial in the electrochemical synthesis of ammonia. The transition metal–based catalysts have received widespread attention. The d-electron layer is prone to gain and lose electrons and reverse donation for the π orbital of N2, which can weaken the dissociation energy of NN ...
Oxygen evolution reaction (OER) plays a key role in many renewable energy technologies such as water splitting and metal-air batteries. Metal-organic frameworks (MOFs) are appealing to design efficient OER electrocatalysts, however, their intrinsic poor conductivity strongly hinders the activity. Here,...
