The higher sensing activity is ascribed to synergistic effect of nitrogen, and oxygen-containing functional groups. The resultant NG is proven to act as a metal-free catalyst with much better performance for am
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 ...
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 ...
If the amount of alcohol that dissociatively adsorbs on a metal oxide surface can be controlled, the aerobic oxidation activity of the catalyst can be intentionally tuned. We thus investigated the relationship between the carboxylate modification of MnO x and the catalytic performance of the resultin...
The family of 2D transition metal carbides, carbonitrides and nitrides (collectively referred to as MXenes) has expanded rapidly since the discovery of Ti3C2 in 2011. The materials reported so far always have surface terminations, such as hydroxyl, oxygen or fluorine, which impart hydrophilicity to...
andpotassiumcyanide solution, slowly dissolved in ammonia solution, and can react with strong alkali. Copper oxide is mainly used in the production of rayon, ceramics, glaze and enamel,battery, petroleum desulfurizer, insecticide,hydrogen production, catalyst, green glass, etc. High-temperaturesintered...
A process for producing a cycloalkanol and/or a cycloalkanone is provided, the process comprising the step of oxidizing cycloalkane with molecular oxygen in the presence of a mixture of metal oxides and/or a composite metal oxide, each containing cerium
Developing metal-free, carbon-based catalysts to replace platinum-based catalysts for oxygen reduction reactions (ORRs) is an emerging area of research. In recent years, different carbon structures including carbon doped with IIIA-VIIA heteroatoms (C–M site-based, where M represents the doped hete...
the main reduction pathway that recycles NO3−to NH4+is dissimilatory nitrate reduction to ammonia. However, our knowledge of the global nitrogen cycle was limited until the discovery of an alternative anoxic process that involves the use of redox metals as catalysts. For example, the anoxic mari...
25. A catalyst effective for at least partially oxidizing a reactant gas comprising at least one hydrocarbon and oxygen to a product stream comprising hydrogen and carbon monoxide said catalyst comprising (a) at least one oxidized metal wherein the metal is selected from the group consisting of ...
