英文摘要: An increasingly level of one of the important greenhouse gas, CO2, in the atmosphere from anthropogenic human activities has several adverse consequences and thus, chemical transformation of carbon dioxide into useful, renewable and environmentally friendly products is becoming an important research problem. In the present investigation, we have developed photocatalyst of graphene oxide modified with cobalt metallated aminoporphyrin (GO-Co-ATPP) for conversion of CO2 to formic acid under visible light. The efficiency of nanohybrid photosynthetic conversion of formic acid from carbon-dioxide is 96.49 μmol for 2 h. We have used XRD, SEM, HR-TEM, AFM, thermogravimetric analysis, BET measurement to establish the structural and physical properties along with infrared spectroscopy and Raman spectroscopy for chemical properties of GO-Co-ATPP. The photocatalyst was significantly effective for NADH photoregeneration with cumulative 48.53% over time and photoelectrochemical measurement showed photocurrent properties. These results strongly suggest that the GOCo-ATPP photocatalyst materials may open new vistas in conversion of CO2 into useful and environmentally friendly products as well as energy applications. © 2018 Elsevier Ltd.
