Ultrathin tungsten-doped hydrogenated titanium dioxide nanosheets for solar-driven hydrogen evolution

Abstract

Titanium dioxide (TiO2) nanosheets can effectively convert solar energy into hydrogen energy through water splitting. However, traditional TiO2 photocatalysts often rely on the addition of precious metals or the construction...

Scaling up the charge transfer on Pd@Ti3C2Tx–TiO2 catalysts: a sustainable approach for H2 generation via water splitting

“…26 The employment of cocatalysts on TiO 2 has been found to be more effective for sustainable water splitting. 27,28 Cocatalysts with the ability to quench the electrons from semiconductor systems can be effective for excellent charge transportation, specifically in water-splitting reactions. 29,30 The higher charge separation ability of the cocatalyst is attributed to its chemical properties (i.e., conductivity and stability).…”

Optimizing the performance of Auy/Nix/TiO2NTs photoanodes for photoelectrochemical water splitting

“…13,14 However, large bandgap implying weak solar light absorption and high carrier recombination rates are major drawbacks which can be overcome by chemical modication in the design of the photoanode material. 15 The modication strategies may be directed to band gap reduction via chemical doping, 16 retardation of charge recombination by heterojunction formation with other materials 17,18 and enhancing solar energy harvesting through surface sensitization. [19][20][21] It is widely acknowledged that doping of transition metal ions can help reducing the band gap thereby extended solar energy absorption to the visible range while acting as a trap for the photogenerated electrons thus suppressing the carrier recombination rate.…”
