氯氧铋BiOCl基异质结具有较高的光生电子和空穴的分离率，在光催化污染物降解方面得到了广泛应用。然而，由于BiOCl基异质结中光生电子和空穴难以实现定向迁移，导致其氧化还原能力减弱，限制了其在光催化有机物定向转化方面的应用。针对上述问题，本项目拟以表面氧空位丰富的BiO1-xCl薄片作为基体，采用逐层自组装法，构建BiO1-xCl@MOFs前驱体，将MOFs热解，制备得到由薄层石墨碳均匀包覆的金属氧化物与BiO1-xCl复合而成的Z型(MOx@TC)/BiO1-xCl异质结。通过调控氧空位的位置，实现该Z型异质结中光生电子和空穴的定向迁移，达到足够高的氧化能力将水氧化成羟基自由基，同时利用MOFs热解产生的薄层石墨碳对有机物的吸附与活化作用，降低苯羟基化制苯酚反应的活化能，实现在可见光驱动下水氧化苯制苯酚，拓展BiOCl基光催化剂在有机物定向转化领域的应用范围。

BiOCl-based heterojunctions have attracted numerous attentions as the photocatalysts of pollutant degradation, due to their high separation efficiency of photo-generated electrons and holes. However, the redox abilities of such heterojunctions can be reduced by the uncontrollable migration of photo-generated electrons and holes, limiting their applications in photocatalytic directional conversions of organic compounds. Accordingly, in this project, we propose to build Z-scheme (MOx@TC)/BiO1-xCl heterojunctions based on BiO1-xCl and carbon thin layer (TC) uniformly coated metal oxide semiconductors (MOx@TC), where BiO1-xCl is formed by introducing controllable amounts of surface oxygen vacancy (VO) to BiOCl. In the synthetic process, BiO1-xCl@MOFs fabricated by layer-by-layer method will be chosen as the pyrolytic precursor of (MOx@TC)/BiO1-xCl. The directional migration of photo-generated electrons and holes can be obtained by controlling the location of oxygen vacancy, leading to the high enough redox ability of the heterojunctions to oxidize H2O into ∙OH; the carbon thin layer derived from MOFs can favor the adsorption and activation of organic compounds, decreasing active energy of the “hydroxylation of bezene by H2O to phenol” reaction. Combining these favourable structural features, the Z-scheme (MOx@TC)/BiO1-xCl heterojunctions can act as photocatalysts of “hydroxylation of bezene by H2O to phenol” reaction and expand applications of BiOCl-based heterojunctions to directional conversions of organic compounds.
