The present study describes the synthesis, characterization, and evaluation of cobalt(ii) phthalocyanine embedded bismuth oxyhalide (CoPc@Bi24O31Br10) for the photoreduction of CO2 into methanol selectively using triethylamine (TEA) as a sacrificial donor under visible light illumination. The highest yield of methanol was found to be 3485.3 μmol per g of the photocatalyst with a methanol formation rate of 145.2 μmol h-1 g-1. The developed photocatalyst was found to be quite stable and showed comparable results for five recycling runs without any significant loss in efficiency. Importantly, no significant leaching of the complex was observed even after the fifth run.
本研究描述了嵌入酞菁钴（II）的卤氧化铋（CoPc@Bi24O31Br10）的合成、表征及评估，该材料用于在可见光照射下以三乙胺（TEA）作为牺牲供体将二氧化碳选择性光还原为甲醇。发现甲醇的最高产率为每克光催化剂3485.3微摩尔，甲醇生成速率为145.2微摩尔·小时-1·克-1。所开发的光催化剂相当稳定，在五次循环运行中显示出可比的结果，且效率没有任何显著损失。重要的是，即使在第五次运行后也未观察到配合物的显著浸出。
