One-pot solvothermal synthesis of Bi2S3-CdS sensitized TiO2 NT films for improved photocatalytic performance
H2 energy causes the increasing attention as the green, environmental friendly energy style, and photocatalytic H2 production is the effective strategy by the inexhaustible solar energy conversion. Herein, CdS-Bi2S3 nanoparticles were decorated on TiO2 nanotube arrays (TiO2 NTs) via one-pot solvothermal synthesis method. The cosensitization effectively extended the optical response region, reduced electron/hole recombination and strengthened the photocatalytic H2 evolution performance. The high photocatalytic H2 evolution rate (79.92 μmol·cm−2·h−1) was obtained by TiO2 NTs/Bi2S3CdS, and the photocatalyst also exhibited dramatically high stability. The photocatalytic water splitting for H2 evolution mechanism and charge carrier transportation were proposed.
