TiO nanoparticles as solar cells and photocatalysts caused extensive attention in solar energy utilization and environment remediation due to the high photoelectrochemical performance. We demonstrated a novel approach to fabricate big-leaf hydrangea-like BiS-BiOBr self-assembled by superthin nanosheets on TiO nanotube arrays (TiO NTs/BS-BiOBr). Results indicated that the BiS-BiOBr co-sensitization showed higher photoelectric conversion efficiency than the single BiS or BiOBr sensitization. More remarkably, TiO NTs/BS-BiOBr showed excellent photoelectrocatalytic (PEC) removal of MB, MO, RhB and Cr(VI). The remarkable PEC performance could be attributed to the strong visible light absorption and effective electron transportation at the interface of TiO/BS-BiOBr. The high photoelectrochemical performances indicate that the TiO NTs/BS-BiOBr could work as potential photoelectric materials for large-scale applications in the photoelectrochemical energy conversion and pollutant removal.
TiO 纳米颗粒作为太阳能电池和光催化剂，由于具有高光电化学性能，在太阳能利用和环境修复方面引起了广泛关注。我们展示了一种在 TiO 纳米管阵列（TiO NTs/BS-BiOBr）上由超薄片自组装制备大叶片绣球花状 BiS-BiOBr 的新方法。结果表明，BiS-BiOBr 共敏化显示出比单 BiS 或 BiOBr 敏化更高的光电转换效率。更显著的是，TiO NTs/BS-BiOBr 对 MB、MO、RhB 和 Cr(VI) 的光电催化（PEC）去除具有优异的性能。显著的 PEC 性能可归因于 TiO/BS-BiOBr 界面处的强可见光吸收和有效的电子输运。高光电化学性能表明，TiO NTs/BS-BiOBr 可用作光电化学能量转换和污染物去除等大规模应用的潜在光电材料。
