Journal ArticleDOI
Selective charge transfer to dioxygen on KPF6-modified carbon nitride for photocatalytic synthesis of H2O2 under visible light
TL;DR: In this article, a carbon nitride (CN) photocatalyst was selected for this purpose, which greatly enhanced the apparent quantum yield (AQY) of H2O2 production in the UV and visible light region.
Journal ArticleDOI
Spontaneous Generation of H2O2 and Hydroxyl Radical through O2 Reduction on Copper Phosphide under Ambient Aqueous Condition.
TL;DR: Cu xP is proposed as a solid reagent that can activate dioxygen to generate reactive oxygen species in ambient aqueous condition, which is more facile to handle and store than liquid/gas reagents (e.g., H2O2, Cl2, O3).
Journal ArticleDOI
Synergic photocatalytic effects of nitrogen and niobium co-doping in TiO2 for the redox conversion of aquatic pollutants under visible light
Jonghun Lim,Palanichamy Murugan,Narayanan Lakshminarasimhan,Jae Young Kim,Jae Sung Lee,Sang Hyup Lee,Sang Hyup Lee,Wonyong Choi +7 more
TL;DR: In this paper, Nitrogen and niobium co-doped TiO 2 was synthesized by a simple sol-gel method and its visible light photocatalytic activities were compared with bare, N-, N-, and Nbdoped (N,Nb)-TiO 2.
Journal ArticleDOI
Graphene oxide embedded into TiO2 nanofiber: Effective hybrid photocatalyst for solar conversion
TL;DR: In this article, a one-dimensional TiO2 nanofibers (NFs) in which graphene oxide (GO) sheets were incorporated (GO-TiO2 NFs) were prepared by using a sol-gel method and an electro-spinning technique.
Journal ArticleDOI
•OH radicals determined photocatalytic degradation mechanisms of gaseous styrene in TiO2 system under 254 nm versus 185 nm irradiation: combined experimental and theoretical studies
Jiangyao Chen,Jiangyao Chen,Zhigui He,Yuemeng Ji,Guiying Li,Taicheng An,Taicheng An,Wonyong Choi +7 more
TL;DR: In this paper, the photocatalytic transformation mechanisms of styrene, were compared in TiO2 system under ultraviolet (UV) and vacuum ultraviolet (VUV) irradiations, and the increased efficiencies were contributed from enhanced production of OH through VUV photolysis of H2O and O2.
