Journal ArticleDOI

New nanoporous carbon materials with high adsorption capacity and rapid adsorption kinetics for removing humic acids

TL;DR: In this paper, a new nanoporous carbon materials (SMC1), which were produced using silica sol particles as templates, showed higher and faster adsorption of humic acids than two commercial activated carbons (F400 and Norit SA).
Journal ArticleDOI

Comparative Study of Homogeneous and Heterogeneous Photocatalytic Redox Reactions: PW12O403- vs TiO2

TL;DR: Kinetic studies using tert-butyl alcohol as an OH radical scavenger suggest that OH radicals are the sole dominant photooxidant in POM-mediated degradations regardless of the kind of substrates tested, whereas both OH radicals and direct hole transfers take part in TiO2 photocatalysis.
Journal ArticleDOI

Dual-components modified TiO2 with Pt and fluoride as deactivation-resistant photocatalyst for the degradation of volatile organic compound

TL;DR: In this article, the photocatalytic degradation of Toluene was carried out on a glass plate with a small air gap (50μm), and it was observed that F-TiO2/Pt film generated the largest amount of mobile OH radicals that migrate through the air gap.
Journal ArticleDOI

UV photolytic mechanism of N-nitrosodimethylamine in water: dual pathways to methylamine versus dimethylamine.

TL;DR: A new mechanistic pathway of NDMA photolysis to DMA is revealed by identifying the factors influencing the photolytic pathway and involving the role of NO2-.
Journal ArticleDOI

Highly enhanced photocatalytic oxidation of CO on titania deposited with Pt nanoparticles: kinetics and mechanism

TL;DR: The effects of nanosized Pt deposits on TiO 2 particles on the photocatalytic oxidation of gaseous CO were investigated in this article, where Pt was photodeposited directly on a TiO2 -coated glass plate with a typical Pt loading of ∼3.5 kg.
