Photocatalytic reduction of CO 2 into methanol and ethanol over conducting polymers modified Bi 2 WO 6 microspheres under visible light

A Review of Direct Z‐Scheme Photocatalysts

“…Nevertheless, compared with other technologies, photocatalytic CO 2 reduction for solar fuel production is still an enormous challenge because of its low solar‐energy‐conversion efficiency, which is primarily attributed to the rapid electron–hole recombination rate on the semiconductor . Thus, it is necessary to develop advanced photocatalysts with good electron–hole separation efficiency . Recent studies have indicated that building direct Z‐scheme photocatalysts is one of the best strategies to prepare highly efficient photocatalysts for CO 2 reduction.…”

Selective photocatalytic reduction of CO2 by H2O/H2 to CH4 and CH3OH over Cu-promoted In2O3/TiO2 nanocatalyst

“…Accordingly, the development of an efficient photocatalytic system for reduction of CO 2 to fuels like methane and methanol provides a topic of great interest, a promising way to clean, low-cost and sustainable fuel production. A number of researchers have been focused on photocatalytic CO 2 reduction by H 2 O to fuels [6][7][8][9].…”

“…. Reactions in Eqs (8)(9)(10). divulged production of CO, CH 3 OH and CH 4 through utilization of H + ions and electrons.Therefore, it could be seen, that CO 2 was firstly converted to CO by reduction reaction, whereas CO should pass through various steps to be ultimately converted to CH 3 OH and CH 4 .…”
