Because of its mild reaction condition, relatively high denitrification efficiency and ability of combined removal of various pollutants, the flue gas denitrification technology based on oxidation theory has become a new and feasible method for flue gas denitrification. The technology has been applied extensively and studied in depth. This paper reviews the influencing factors, reaction mechani...

Phase stability of transition metal nanoparticles during exposure to elevated temperature and gaseous environment is a highly relevant topic in catalytic research with broad implications for rationalization of catalytic properties and design of new catalytic materials. For Pd based catalysts, the phase stability under oxidizing environment represents an important topic as many Pd based catalyst...

The synthesis of two novel catalytic materials based on vanadium mixed oxides has been described in present study. first material was a Vanadium-Phosphorous oxide (VPO) carbon-supported with fibrous morphology and very high surface area, stable under oxidizing conditions up to 350 °C. other is bulk VPO structure obtained after optimizing the calcination supported carbon fiber catalyst, which pr...

An effective way to improve sensor selectivity and stability is the use of catalytic filters to block interfering and poisoning gas molecules from reaching the sensor surface. Mesoporous silica with high resistivity and hugh surface areas are ideally suited as a base material for this application. When impregnated with proper catalysts, mesoporous silica has a great potential to eliminate respo...

Homogeneous Cu/TEMPO catalyst systems (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) have emerged as some of the most versatile and practical catalysts for aerobic alcohol oxidation. Recently, we disclosed a (bpy)Cu(I)/TEMPO/NMI catalyst system (NMI = N-methylimidazole) that exhibits fast rates and high selectivities, even with unactivated aliphatic alcohols. Here, we present a mechanistic inve...

CO oxidation over platinum group metals has been investigated for some eight decades by many researchers and is considered to be the best understood catalytic reaction. Nevertheless, there has been a renewed interest in CO oxidation recently because of its technological importance in pollution control and fuel cells. Removal of COx from automobile exhaust is accomplished by catalytic converters...

[1] The ozonolyses of six monoterpenes (a-pinene, b-pinene, 3-carene, terpinolene, a-terpinene, and myrcene), two sesquiterpenes (a-humulene and b-caryophyllene), and two oxygenated terpenes (methyl chavicol and linalool) were conducted individually in Teflon chambers to examine the gas-phase oxidation product and secondary organic aerosol (SOA) yields from these reactions. Particle size distri...
