Molecular level insight into the interaction between volatile organic compounds (VOCs) and aerosols is crucial for improvement of atmospheric chemistry models. In this paper, the interaction between adsorbed toluene, one of the most significant VOCs in the urban atmosphere, and the aqueous surface of aerosols was studied by means of combined molecular dynamics simulations and ab initio quantum ...

ti-mcm-41 was synthesized at ph 3, 7 and 11. the titanium content was determined by aas and found to be 4%, 3.2% and 4.5%, respectively. in order to increase the titanium content in ti-mcm-41, ti(iv) ions were grafted onto ti-mcm-41 using ticl4 in toluene and ti(obu)4 in ethanol. the incorporation of ti was determined to be 28% and 30%, respectively. the oxidation of olefins such as cyclopenten...

This study evaluates the significance of glyoxal acting as an intermediate species leading to secondary organic aerosol (SOA) formation from aromatic hydrocarbon photooxidation under humid conditions. Rapid SOA formation from glyoxal uptake onto aqueous (NH4)2SO4 seed particles is observed in agreement with previous studies; however, glyoxal did not partition significantly to SOA (with or witho...

Chlorinated volatile organic compounds (CVOCs), even in small quantities, can cause Pt-based catalyst poisoning. Improving the low-temperature chlorine resistance of catalysts is vital importance for industrial application, although it remains challenging. Considering actual production, a TiO2-supported ternary metal was prepared this work to study catalytic oxidation multicomponent VOCs (tolue...
