(a) TEM image showing the loading of N-TiO2 nanoparticles onto g-C3N4 nanosheets, and (b) proposed scheme involved in photocatalytic CO2 conversion (taken with permission from [62]). (c) TEM image showing the 2-D nanostructure of TiO2 nanosheets coupled with g-C3N4 nanosheets, and (d) schematic view of the interfacial charge transfer within TNS-CNN with the proposed photocatalytic CO2 conversion mechanism (taken with permission from [63]).
