Journal ArticleDOI
Highly enhanced photocatalytic degradation of tetramethylammonium on the hybrid catalyst of titania and MCM-41 obtained from rice husk silica
Surachai Artkla,Surachai Artkla,Wooyul Kim,Wonyong Choi,Jatuporn Wittayakun,Jatuporn Wittayakun +5 more
TL;DR: In this paper, a hybrid photocatalyst consisting of TiO2 and the mesoporous support was prepared by loading the nanoparticles on MCM-41 which was synthesized from silica obtained from rice husk (abundant agricultural waste in Thailand).
Journal ArticleDOI
Visible Light Photocatalysts Based on Homogeneous and Heterogenized Tin Porphyrins
TL;DR: The visible light photocatalysis using water-soluble tin porphyrin (s-SnP, [Sn(OH2)2(TPyHP)](NO3)6) was investigated in this article.
Journal ArticleDOI
Distorted Carbon Nitride Structure with Substituted Benzene Moieties for Enhanced Visible Light Photocatalytic Activities
TL;DR: This study proposes a simple strategy for chemical structural modification of carbon nitride to boost the visible light photocatalytic activity by designing the CN structure in which the nitrogen of tertiary amine is substituted with a benzene molecule connected by three heptazine rings.
Journal ArticleDOI
TiO2 modified with both phosphate and platinum and its photocatalytic activities
Jungwon Kim,Wonyong Choi +1 more
TL;DR: In this paper, a new hybrid modification method of TiO2 photocatalyst was developed and investigated, where the two surface species acted synergically to enhance the photocatalytic activity.
Journal ArticleDOI
Study on Fe(VI) species as a disinfectant: quantitative evaluation and modeling for inactivating Escherichia coli.
TL;DR: Ferrate (Fe(VI)) has high potentials as a multi-purpose water treatment chemical acting as an oxidant, coagulant, and disinfectant, but little detail has been reported concerning its biocidal ability.
