摘要

寻找将二氧化碳转化为燃料的有效而特殊的催化材料无疑是一项重大挑战。本研究利用质子化硫化铋纳米颗粒（Bi2S3 NSs）与 Ti3C2(OH)2 QDs（MQDs-OH）的静电自组装，制备了三维多孔球形结构的 MXene 量子点/Bi2S3（MBS）复合材料。优化后的 MBS 材料具有出色的窄带隙（Eg=1.24 V（相对于 NHE））和催化 CH3OH 的高选择性和高效性，产量高达 694.7 µmol/g。这项研究可能为开发通过吸附大气中的二氧化碳来生产 CH3OH 的多维光催化剂带来新的思路。

Alkalized MQDs /Bi2S3 Porous Structure For Efficient Photocatalytic CO2 Reduction

Finding effective and specific catalytic materials for the transformation of carbon dioxide into fuel is indisputably a significant challenge. In this study, 3D porous sphere structure MXene quantum dot/Bi2S3 (MBS) composites were prepared using electrostatic self-assemblage of protonated Bismuth sulphide nanoparticles (Bi2S3 NSs) with Ti3C2(OH)2 QDs (MQDs-OH). The optimized MBS material demonstrates an excellent narrow band gap (Eg=1.24 V (vs. NHE)) and high selectivity and efficiency in catalyzing CH3OH, delivering impressive yields of up to 694.7 µmol/g. This study may lead to a new approach to the development of multidimensional photocatalysts for CH3OH production by adsorption of atmospheric CO2.
