The combustion mechanism of ethylene by atomic oxygen on silver (110) was investigated with the modern tools of surface science. Ethylene was oxidatively dehydrogenated by the adsorbed atomic oxygens to surface hydroxide and a surface residue of carbon atoms. The surface hydroxide intermediates rapidly reacted to yield water and adsorbed atomic oxygen, and the carbon atoms were subsequently oxi...

A comprehensive study on the asymmetric gold-catalyzed cycloisomerization reaction of heteroatom tethered 1,6-enynes is described. The cycloisomerization reactions were conducted in the presence of the chiral cationic Au(I) catalyst consisting of (R)-4-MeO-3,5-(t-Bu)(2)-MeOBIPHEP-(AuCl)(2) complex and silver salts (AgOTf or AgNTf(2)) in toluene under mild conditions to afford functionalized bic...

Currently, and looking forward, there is an ever increasing demand to perform chemical transformations with optimized atom and energy efficiency. In parallel, there is also growing interest in diversification of chemical feedstocks from more traditional ones. For example, effective and economic transformation of biorenewable chemical feedstocks and shale-gas, are just two that can be highlighte...

Abstract Silver orthophosphate (Ag 3 PO 4 ) is an attractive photocatalytic catalyst for disinfection and degradation, but its instability arising from silver release generates significant environmental issue. Aiming to develop a highly efficient environmental-friendly catalyst, we synthesized Ag nanoparticle incorporated hierarchical porous silica @ h -SiO 2 as novel high-performance without o...

The promotion of Ag–ZSM-5 by cerium for the selective catalytic reduction (SCR) of NO with methane in the presence of an excess of oxygen was studied in this work. Ce–Ag–ZSM-5 catalyzes the CH4-SCR of NOx over the temperature range of 450–600◦C. Rate measurements of NO reduction to N2 under SCR conditions and of the competing CH4 oxidation by O2 (CH4 combustion) show that incorporation of a sma...
