Influence of the method of platinum deposition on activity and stability of Pt/TiO2 photocatalysts in the photocatalytic oxidation of dimethyl methylphosphonate

Novel photocatalysts based on Cd1−Zn S/Zn(OH)2 for the hydrogen evolution from water solutions of ethanol

“…The spectrum of Cd 0.2 Zn 0.8 S is typical of the single-phase solid solution. The absorption edge at i n t e r n a t i o n a l j o u r n a l o f h y d r o g e n e n e r g y 3 9 ( 2 0 1 4 ) 1 8 7 5 8 e1 8 7 6 9 456 nm is typical of the solutions with the Cd:Zn ratio equal to 2:8 [19,30]. The spectra of the composite photocatalysts B90, B110, and C90 demonstrate a combination of two spectra due to the absorption of Cd 1Àx Zn x S (range 450e500 nm) and ZnO (range 380e450 nm).…”

“…These techniques were described in detail elsewhere [19]. In the case of SCR, the sulfide-based photocatalysts were impregnated with an H 2 PtCl 6 solution.…”

Synthesis of 3D ordered macroporous TiO2-supported Au nanoparticle photocatalysts and their photocatalytic performances for the reduction of CO2 to methane

“…It is generally accepted that the noble metal nanoparticles deposited on the semiconductor may improve charge separation, facilitate CO 2 activation, and provide more catalytic active sites [13]. The high photocatalytic activity of TiO 2 -supported noble metal nanoparticles can be attributed to plasmon-excited electrons in Au nanoparticles.…”

Zirconium Phosphate Heterostructures as Catalyst Support in Hydrodeoxygenation Reactions

“…The Pt 4f core level spectrum the PtMo/PPH catalyst shows two doublets, as can be clearly seen in Figure 7. The Pt 4f7/2 component located at 71.1 eV corresponds to metal Pt and that located at 72.5 eV is characteristic of the Pt 2+ ion corresponding to PtO [34]. After catalysis, both of the two contributions due to Pt 0 and PtO are also observed, the contribution of the metallic phase being the most important one.…”
