Photochemistry on nonreactive and reactive (semiconductor) surfaces

“…For example, H2S, which is a byproduct in the coal and petroleum industry, can be oxidized to S at the CdS semiconductor surface.460 A quantum yield of ~50% has been reported for the reaction between sulfide anions and photogenerated valence band holes Addition of sulfite also facilitates the H2S cleavage process by removing S from this surface to generate a desirable product, thiosulfate. [461][462][463] In a similar way,…”

Urea Photosynthesis from Inorganic Carbon and Nitrogen Compounds Using TiO2 as Photocatalyst

“…Photoinduced conversion of CO 2 to useful chemicals with the use of semiconductor particles as photocatalysts has been intensively studied using bulk and quantized particles. In the case of using bulk semiconductor particles of high stability such as TiO 2 and SiC, several kinds of reduction products including formate − and formaldehyde − were obtained in aqueous solutions in the absence of any hole scavenger. However, the amounts of products were very small in many cases, and it is not always easy to reproduce the results.…”

Design, preparation and characterization of ruthenium dioxide/titanium dioxide catalytic surfaces active in photooxidation of water

“…Details of this system have been reported previously. 6 Our aim was to explore the role of the catalyst in the photochemical oxidation of water induced by visible light using persulfate ions to oxidize the triplet excited state of Ru(bpy)32+ to Ru(bpy)33+. (Note, there is no dark reaction under the present experimental conditions).…”

“…As shown in eq 3, the 02 generation goes through excited Ru(bpy)32+ with 4Ru(bpy)33+ + 2H20 hv Ru02'xH20/Ti02 4Ru(bpy)32+ + 02 + 4H+ (3) subsequent oxidation to Ru(bpy)33+ by S2082-present in the system. 6 The Ru(bpy)33+ oxidizes water to 02 in the presence of the catalyst. Figure 10 shows that 02 generation is proportional to the first power of the light intensity.…”
