A self-assembled 3D Pt/TiO₂ architecture for high-performance photocatalytic hydrogen production

Abstract

A 3D Pt/TiO2 architecture assembled from 1D nanowires has been designed and successfully prepared by an environmentally-friendly one-pot solvothermal process. The formation mechanism has been investigated and the unique architecture exhibits an excellent photocatalytic hydrogen production rate as high as 13.33 mmol h(-1) g(-1), the corresponding apparent quantum efficiency reaches 34%.

Ultrathin Anatase TiO2 Nanosheets for High‐Performance Photocatalytic Hydrogen Production

“…As a comparison, the H 2 evolution rate of sample 1 is about 17.86 mmol h −1 g −1 by an enhancement of 106%, where the corresponding apparent QE has been determined to be 34.2% at 365 nm. To the best of our knowledge, this value of QE exceeded the results obtained with some other TiO 2 ‐based photocatalysts reported so far . In addition to the remarkable photocatalytic activity, sample 1 exhibits a very good stability as a photocatalyst.…”

Direct microwave–hydrothermal synthesis of Fe-doped titania with extended visible-light response and enhanced H2-production performance

“…Searching for new clean, renewable energy resources has thus become a top priority. Because visible-light energy represents approximately 50% of total solar energy, using semiconductor catalysts to generate H 2 by water splitting under visible-light irradiation has become a highly desirable method [1][2][3][4][5].…”

Size-dependent activity and selectivity of carbon dioxide photocatalytic reduction over platinum nanoparticles

“…However, neither of these approaches is ideal for CO2PR. For photocatalysis, loading with different amounts of Pt would cause the imbalance of light absorption of the supporting semiconductor 24 , 25 ; meanwhile, it also cannot tune the size of Pt NPs precisely. Smaller Pt NPs may still exist with excessive Pt loadings, and the size effect may not be reflected accurately.…”
