英文摘要 | In this work, we report a comprehensive investigation on the catalytic performance and mechanism of mayenite electride [Ca24Al28O64](4+)(O2-)(2-x) (e(-))(2x) (C12A7:e(-)) as an electron donor type promoter to P25 in hydrogen production from water. Herein, the C12A7:e(-)-P25 composites were prepared by simply mechanical mixing method. The optimum H-2 evolution rate reached 663 mu mol h(-1) g(-1) which was 43.9 times higher than that of pure P25, when 0.25 wt% C12A7:e(-) was added. Mott-Schottky plots and X-ray photoelectron spectroscopic results confirmed the injection of electrons encaged in C12A7:e(-) to the conduction band of P25. Surface photovoltage measurements and photoluminescence results showed that the introduction of C12A7:e(-) promoted the efficient separation of photogenerated electron-hole pairs of P25, which illustrated the formation of built-in electric field from P25 to C12A7:e(-) due to the difference in work function. The present work provides new promoter choices for photocatalytic studies. |
