The Effect of Interfacial Chemical Bonding in TiO2-SiO2 Composites on Their Photocatalytic NOx Abatement Performance
The chemical bonding of particulate photocatalysts to supporting material surfaces is of great importance in engineering more efficient and practical photocatalytic structures. However, the influence of such chemical bonding on the optical and surface properties of the photocatalyst and thus its photocatalytic activity/reaction selectivity behavior has not been systematically studied. In this i...
متن کاملBaKCo/CeO2 catalysts for diesel soot and NOx abatement
Introduction Soot particles and NOx are the main pollutants from diesel engines. Good alternatives to abate these contaminants are the use of catalytic filters, which burn the soot particles, and NOx traps which adsorb the NOx during normal operation and released them during reduction cycles [1]. We recently studied BaK/CeO2 catalysts for this application[2]. Barium plays the role of NOx adsorb...
متن کاملNox and Diesel Soot Abatement over Catalytic Traps Based on Mixed Trasition Metal Oxides
Nanostructured perovskite-type oxides catalysts La1-xAxNi1-yByO3 (where A = Na, K, Rb and B = Cu; x = 0, 0.2 and y = 0, 0.05, 0.1), prepared by the solution combustion synthesis method and characterized by BET, XRD, FESEM, and catalytic activity tests in microreactors, proved to be effective in the simultaneous removal of soot and NO, the two prevalent pollutants in diesel exhaust gases in the ...
متن کاملTylosin abatement in water by photocatalytic process.
The photocatalytic degradation of a macrolide (tylosin) has been studied using immobilized titanium dioxide as photocatalyst in a laboratory reactor under UV illumination (365 nm). The degradation of the antibiotic and of the reaction intermediary product was monitored by UV spectrophotometry and HPLC. Three photocatalysts (P25 from Degussa and PC105 and PC500 from Millennium) immobilized on gl...
متن کاملModeling and Simulation of NOx Abatement with Storage/Reduction Catalysts for Lean Burn and Diesel Engines
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...
