Homogeneous and Heterogeneous Photocatalytic Water Oxidation by Persulfate.
Photocatalytic water oxidation by persulfate (Na2 S2 O8 ) with [Ru(bpy)3 ](2+) (bpy=2,2'-bipyridine) as a photocatalyst provides a standard protocol to study the catalytic reactivity of water oxidation catalysts. The yield of evolved oxygen per persulfate is regarded as a good index for the catalytic reactivity because the oxidation of bpy of [Ru(bpy)3 ](2+) and organic ligands of catalysts com...
متن کاملLaCoO3 acting as an efficient and robust catalyst for photocatalytic water oxidation with persulfate.
Cobalt-containing metal oxides [perovskites (LaCoO(3), NdCoO(3), YCoO(3), La(0.7)Sr(0.3)CoO(3)), spinel (Co(3)O(4)) and wolframite (CoWO(4))] have been examined as catalysts for photocatalytic water oxidation with Na(2)S(2)O(8) and [Ru(bpy)(3)](2+) as an electron acceptor and a photosensitizer, respectively. Catalysts with the perovskite structure exhibited higher catalytic activity as compared...
متن کاملMicrowave-assisted Heterogeneous Photocatalytic Oxidation
Photocatalytic oxidation makes use of light of appropriate frequency to activate a catalyst. In the presence of water on the surface of the catalyst, rates of some photocatalytic reactions are slowed. Microwaves are known for an ability to couple with water. Herein a photocatalytic reactor system was integrated with a waveguide allowing for concurrent application of microwaves and photocatalysi...
متن کاملPhotocatalytic Water Oxidation on ZnO: A Review
The investigation of the water oxidation mechanism on photocatalytic semiconductor surfaces has gained much attention for its potential to unlock the technological limitations of producing H2 from carbon-free sources, i.e., H2O. This review seeks to highlight the available scientific and fundamental understanding towards the water oxidation mechanism on ZnO surfaces, as well as present a summar...
متن کاملCrossing the divide between homogeneous and heterogeneous catalysis in water oxidation.
Enhancing the surface binding stability of chromophores, catalysts, and chromophore-catalyst assemblies attached to metal oxide surfaces is an important element in furthering the development of dye sensitized solar cells, photoelectrosynthesis cells, and interfacial molecular catalysis. Phosphonate-derivatized catalysts and molecular assemblies provide a basis for sustained water oxidation on t...
