在本研究中，通过水热反应、硼氢化钠还原和离子层吸附与反应(SILAR)处理，成功地制备了具有增强可见光驱动光催化(PC)和光电化学(PECH)性能的AgBr纳米饼修饰Ti3+自掺杂TiO2纳米棒/纳米片(AgBrTi3+/TiO2NRs/NSS)光电极。随后，对AgBrTi3+/TiO2NRs/NSS光电极进行了一系列的表征。结果表明，在Ti3+/TiO2NRs/NSS表面均匀地修饰了尺寸为110~180 nm的AgBr纳米饼，形成了AgBrTi3+/TiO2NRs/NSS光电极。此外，通过对亚甲基蓝(MB)的降解测定了AgBrTi3+/TiO2NRs/NSS光电极的PC活性。结果表明，在15 0 的可见光照射下，AgBrTi3+/TiO2NRs/NaS光电极具有较高的PC活性(98.7%)，这是由于AgBrTi3+/TiO2NRs/NSS光电极对可见光的捕获能力增强和光生电荷的有效分离所致。因此，AgBr纳米饼和Ti3+对AgBrTi3+/TiO2NRs/NSS光电极的PC和PECH性能有很大的影响。在此基础上，提出并证实了AgBrTi3+/TiO2NRs/NSS体系可能的可见光驱动PC机制。
In the study, AgBr nano-cakes decorated Ti3+self-doped TiO2nanorods/nanosheets (AgBr-Ti3+/TiO2NRs/NSs) photoelectrode with enhanced visible light driven photocatalytic (PC) and photoelectrochemical (PECH) performance has been successfully fabricated by hydrothermal reaction, followed by sodium borohydride reduction and then successive ionic layer adsorption and reaction (SILAR) treatment. Afterwards, series of characterizations were conducted to study the physicochemical properties of AgBr-Ti3+/TiO2NRs/NSs photoelectrode. Results indicated that AgBr nano-cakes with sizes varying from 110 to 180 nm were uniformly decorated on the surface of Ti3+/TiO2NRs/NSs to form AgBr-Ti3+/TiO2NRs/NSs photoelectrode. Moreover, PC activity of AgBr-Ti3+/TiO2NRs/NSs photoelectrode was measured by degradation of methylene blue (MB). It was found that AgBr-Ti3+/TiO2NRs/NSs photoelectrode exhibited higher PC activity (98.7%) than that of other samples within 150 min visible light illumination, owing to the enhancement of visible light harvesting and effective separation of photoproduced charges. Thus, AgBr nano-cakes and Ti3+exerted a huge influence on the PC and PECH properties of AgBr-Ti3+/TiO2NRs/NSs photoelectrode. Furthermore, the possible enhanced visible light driven PC mechanism of AgBr-Ti3+/TiO2NRs/NSs was proposed and confirmed.
