Hydrogen production using Pt-loaded TiO2 photocatalysts

Drastic Layer‐Number‐Dependent Activity Enhancement in Photocatalytic H2 Evolution over nMoS2/CdS (n ≥ 1) Under Visible Light

“…[ 10 ] To effectively retard the recombination of electron-hole pairs, people usually load metals, especially noble metals such as Pt, on the surface of semiconductors as cocatalysts, greatly enhancing the photocatalytic hydrogen evolution activities. [ 11,12 ] However, due to the high-cost and limitedreserve, it is valuable to develop highly effi cient and low-cost noble-metal-free cocatalysts to further facilitate the development of hydrogen evolution. [ 13,14 ] Recently, many reports indicate that MoS 2 can be a good candidate as a cocatalyst, [15][16][17][18][19][20][21][22][23] and many researchers focused on its catalytic activities on some photocatalysts and electrical catalysts in order to replace Pt.…”

ZnO-dotted porous ZnS cluster microspheres for high efficient, Pt-free photocatalytic hydrogen evolution

“…can trap easily the electrons due to its low Fermi level. When compounding with semiconductors, they can serve as electron sinks via the formation of a Schottlky junction and provide effective proton reductions sites for hydrogen evolution with a low kinetic activation barrier 4 5 . However, the noble metal is scarce and expensive, which largely hinders their practical application.…”

Size- and density-controlled photodeposition of metallic platinum nanoparticles on titanium dioxide for photocatalytic applications

“…the crystal form of the substrate and its growth procedure). The success of the procedure can also contribute to wet-synthesis processes of novel structures, 74 as well as in situ photodeposition during a photoelectrochemical process such as water-splitting, hydrocarbon reduction to CO 2 , all methods that benet from the use of methanol as a sacricial reagent. 75…”
