To tackle the issue of global warming, one of the options being considered is to convert CO2 into fuels using renewable energies, such as photochemical conversion of CO2, which could displace fossil use and therefore achieve net emission reduction. [1] However, the current approaches of photocatalytic CO2 conversion suffer from one or multiple of the following drawbacks: 1) the efficiency is far too low for practical large-scale applications; 2) the reaction conditions require elevated temperature or extreme pressure; 3) the need to use precious metal as the catalyst. [2] Overall, the considerable challenge faced by current methods is the development of efficient catalysts based on cheap and earth-abundant elements rather than expensive precious metals, as well as mild reaction conditions to operate. Both of which will contribute to the scalability of the conversion process in order to make any reasonable contribution to the CO2 emission reduction.
