Abstract

The conversion of CO₂ into fuel using photocatalytic technology is critical in reducing greenhouse gas emissions and addressing the energy issue. In this paper, type II heterojunctions of 2D/2D BiOIO₃/Bi-MOF were built using the solvothermal approach. The materials were characterized utilizing methods such as XRD, SEM, TEM, XPS, UV–vis diffuse reflection, and an electrochemical workstation. Under 300 W Xenon lamp irradiation, BiOIO₃/Bi-MOF-30 (BOIOB-30) produced 21.26 μmol/g/h of CO, 1.95 times greater than pure BiOIO₃. This improvement is related to the alteration of BiOIO₃ with lamellar Bi-MOF, which provides more reactive sites and significantly increases the composite's photocatalytic activity.

通过增加二维/二维 BiOIO3/Bi-MOF II 型异质结上的有效界面，提高光催化二氧化碳还原为一氧化碳的能力

利用光催化技术将二氧化碳转化为燃料对于减少温室气体排放和解决能源问题至关重要。本文利用溶解热方法构建了 2D/2D BiOIO3/Bi-MOF 的 II 型异质结。利用 XRD、SEM、TEM、XPS、紫外-可见漫反射和电化学工作站等方法对材料进行了表征。在 300 W 氙灯照射下，BiOIO3/Bi-MOF-30（BIOB-30）产生了 21.26 μmol/g/h 的 CO，是纯 BiOIO3 的 1.95 倍。这种改进与用片状 Bi-MOF 改变 BiOIO3 有关，片状 Bi-MOF 提供了更多的反应位点，显著提高了复合材料的光催化活性。
