| Description: |
The atmospheric concentration of CO2 as the dominant greenhouse gas continues to rise and has become a global environmental issue. Photocatalytic CO2 reduction into solar fuels has been regarded as an ideal solution to reduce CO2 emissions and to use solar energy. Graphitic carbon nitride (g-C3N4) is one of the most promising visible-light-driven photocatalysts for CO2 reduction. Unfortunately, the CO2 reduction performance of g-C3N4 based photocatalyst is normally limited by the inferior charge separation ability and limited CO2 adsorption capacity. In this study, two cooperative strategies, that is, combined host nanostructural design and surface guest grafting, are adopted to overcome the aforementioned drawbacks.
