The photocatalyst-enzyme coupled system for artificial photosynthesis process is one of the most promising methods of solar energy conversion for the synthesis of organic chemicals or fuel. Here we report the synthesis of a novel graphene-based visible light active photocatalyst which covalently bonded the chromophore, such as multianthraquinone substituted porphyrin with the chemically converted graphene as a photocatalyst of the artificial photosynthesis system for an efficient photosynthetic production of formic acid from CO(2). The results not only show a benchmark example of the graphene-based material used as a photocatalyst in general artificial photosynthesis but also the benchmark example of the selective production system of solar chemicals/solar fuel directly from CO(2).
用于人工光合作用过程的光催化剂-酶偶联系统是最有前途的太阳能转换方法之一，可用于合成有机化学品或燃料。在这里，我们报告了一种新型基于石墨烯的可见光活性光催化剂的合成，该光催化剂将生色团（如多蒽醌取代的卟啉）与化学转化石墨烯共价键合，作为人工光合作用系统的光催化剂，以高效地从 CO(2)合成甲酸。研究结果不仅展示了一般人工光合作用中使用基于石墨烯的材料作为光催化剂的基准范例，而且还展示了直接从 CO(2)选择性生产太阳能化学品/太阳能燃料的基准范例。
