| 1 | Fabrication of BiOBr-silicone aerogel photocatalyst in an aqueous system with degradation performance by sol-gel method显示文摘It is a challenge to endow the material with the ability to pollutants degradation while maintaining the oil/water separation performance. Herein, the mixed dispersion of BiOBr photocatalyst and silicone sol was adsorbed in melamine foam. Superhydrophobic BiOBr-silicone aerogel(WCA=154°) was obtained through the transfer melamine foam to an autoclave and reaction at 80℃ for 20 h. The prepared superhydrophobic BiOBr-silicone aerogel can effectively remove the water soluble pollutants which remain within the water phase after oil/water separation. The band gap of the superhydrophobic BiOBr-silicone aerogel was calculated to be 2.71 eV, which shows sensitivity to visible light(458 nm). Through mechanism analysis, it is found that the VB position of BiOBr is at 1.07 eV and the position of CB is at-1.64 eV. Finally, we prepared a superhydrophobic BiOBr-silicone aerogel(5 cm×5 cm×3 cm) for the verification of the large scale preparation. | GE Bo REN GuiNa YANG Hang YANG JingJing PU XiPeng LI WenZhi JIN ChuanYu ZHANG ZhaoZhu | 2020 | Science China(Technological Sciences)2020，63，5： | 4 |

| 4 | SnFe_(2)O_(4)/ZnIn_(2)S_(4)/PVDF piezophotocatalyst with improved photocatalytic hydrogen production by synergetic effects of heterojunction and piezoelectricity显示文摘The polarized electric field inside piezoelectric materials has been proven to be a promising technique to boost photogenerated charge separation.Herein,a novel flexible SnFe_(2)O_(4)/ZnIn_(2)S_(4)/polyvinylidene fluoride((CH2CF2)_(n),PVDF)(P-SZ)film piezophotocatalyst was successfully synthesized by combining PVDF,an organic piezoelectric material,with a SnFe_(2)O_(4)/ZnIn_(2)S_(4)(SFO/ZIS)type II heterojunction photocatalyst.The hydrogen evolution rate of SFO/ZIS heterojunction with a SFO content of 5%is about 846.79μmol·h^(−1)·g^(−1),which is 3.6 times that of pristine ZIS.Furthermore,after being combined with PVDF,the optimum hydrogen evolution rate of P-SZ is about 1652.7μmol·h^(−1)·g^(−1)in the presence of ultrasound,which exceeds that of 5%SFO/ZIS by an approximate factor of 2.0.Based on experimental results,the mechanism of the improved photocatalytic performance of P-SZ was proposed on the basis of the piezoelectric field in PVDF and the formed heterojunction between SFO and ZIS,which effectively boosted the separation of photoinduced charges.This work provides an efficient strategy for multi-path collection and utilization of natural solar and vibrational energy to enhance photoactivity. | Ping Su Dezhi Kong Huaihao Zhao Shangkun Li Dafeng Zhang Xipeng Pu Changhua Su Peiqing Cai | 2023 | Journal of Advanced Ceramics2023，12，9： | 0 |
