研究目的
Investigating the photocatalytic hydrogen evolution performance of a nanoreactor based on SrTiO3 coupled TiO2 nanotubes confined Au nanoparticles under simulated sunlight irradiation.
研究成果
The SrTiO3 modified TiO2NTs confined Au nanoparticles (STO-TiO2NTs@Au) demonstrated enhanced photocatalytic hydrogen evolution performance, attributed to the synergistic effect of electron-donating SrTiO3 and TiO2NTs confinement. This nanoreactor design offers a promising approach for efficient carriers’ separation in photocatalysis.
