The removal of nitrogen oxides emitted by diesel and lean burn engines is one of the most important targets in catalytic exhaust aftertreatment research. Besides the selective catalytic reduction (SCR) reaction with ammonia the most promising approach is the NOx Storage and Reduction Catalyst (NSR) which utilizes the nitrogen oxides storage on barium sites to form nitrates during the lean phase...

Selective hydrogenation of halonitrobenzenes into haloanilines represents a green process to replace the environmentally unfriendly non-catalytic chemical reduction in industry. However, this transformation often suffers from serious dehalogenation due easy break carbon-halogen bonds on metal surfaces. Modulations electronic structure supported Pd nanoparticles Lewis-basic layered double hydrox...

effects of water on the catalytic performances of movtenbo catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. presence of water induces some structural modif...

Nitrogen oxides released from the combustion of fossil fuels are one main air pollutants. Selective catalytic reduction technology is most widely used nitrogen oxide removal in industry. With development nanomaterials science, more and novel being as catalysts for selective oxides. In recent years, metal-organic frameworks (MOFs), with large specific surface areas abundant acid metal sites, hav...
