Combining adsorption and photocatalysis is an effective strategy for degrading organic pollutants. Here, BiVO₄@diatomite composite photocatalyst (BiVO₄@diatomite CP) was prepared by hydrothermal synthesis from Bi(NO₃)₃·5H₂O glycerin solution, NH₄VO₃ solution and diatomite. BiVO₄@diatomite/microcrystalline cellulose/PVB composite fibers (BiVO₄@diatomite/MCC/PVBCFs) were prepared from BiVO₄@diatomite CPs, microcrystalline cellulose (MCC) and PVB ethanol solution using the electrospinning method. BiVO₄@diatomite/MCC/PVBCFs were then mixed with pulp fibers to prepare the visible light-responsive photocatalytic paper. BiVO₄@diatomite CP with a BiVO₄/diatomite ratio of 6:4 had good interface states and displayed good photocatalytic activity with 64.32% degradation of methylene blue (MB) after 4 h. A PVB ethanol solution (6%) was formulated with BiVO₄@diatomite CP and MCC to provide an ethanol spinning solution (12% solid) to prepare BiVO₄@diatomite/MCC/PVBCFs (3:3:4). The resulting fibers had smooth surfaces, compact structures and exhibited good photocatalytic activity (66.80% and 56.80% degradation of MB and formaldehyde (HCHO), respectively, after 4 h). Photocatalytic paper containing 18% BiVO₄@diatomite/MCC/PVBCFs had good photocatalytic activity with 50.20% degradation of HCHO after 4 h. This paper also had good physical properties and has the potential to be used for the photocatalytic degradation of indoor air pollutants, such as HCHO.

吸附和光催化相结合是降解有机污染物的有效策略。在此，通过水热合成由Bi（NO ₃）₃ ·5H ₂ O甘油溶液，NH ₄ VO ₃溶液和硅藻土制备BiVO ₄硅藻土复合光催化剂（BiVO ₄硅藻土CP）。用静电纺丝法由BiVO ₄硅藻土CP，微晶纤维素（MCC）和PVB乙醇溶液制备BiVO ₄硅藻土/微晶纤维素/ PVB复合纤维（BiVO ₄硅藻土/ MCC / PVBCF）。BiVO ₄然后将硅藻土/ MCC / PVBCF与纸浆纤维混合以制备可见光响应性光催化纸。BiVO ₄ /硅藻土比为6：4的BiVO ₄硅藻土CP具有良好的界面态，并显示出良好的光催化活性，4 h后亚甲基蓝（MB）降解64.32％。用BiVO ₄硅藻土CP和MCC配制PVB乙醇溶液（6％）以提供乙醇纺丝溶液（12％固体）以制备BiVO ₄硅藻土/ MCC / PVBCF（3：3：4）。所得纤维具有光滑的表面，致密的结构并表现出良好的光催化活性（4小时后MB和甲醛（HCHO）的降解分别为66.80％和56.80％）。含18％BiVO _4的光催化纸硅藻土/ MCC / PVBCFs具有良好的光催化活性，4 h后HCHO降解50.20％。该纸还具有良好的物理性能，并具有用于光催化降解室内空气污染物（例如HCHO）的潜力。
