description | Sustainable conversion of CO<sub>2</sub> to fuels using solar energy is highly attractive for fuel production. This work focuses on the synthesis of porous graphitic carbon nitride nanobelt catalyst (PN-g-C<sub>3</sub>N<sub>4</sub>) and its capability of photocatalytic CO<sub>2</sub> reduction. The surface area increased from 6.5 m<sup>2</sup>·g<sup>−1</sup> (graphitic carbon nitride, g-C<sub>3</sub>N<sub>4</sub>) to 32.94 m<sup>2</sup>·g<sup>−1</sup> (PN-g-C<sub>3</sub>N<sub>4</sub>). C≡N groups and vacant N<sub>2C</sub> were introduced on the surface. PN-g-C<sub>3</sub>N<sub>4</sub> possessed higher absorbability of visible light and excellent photocatalytic activity, which was 5.7 and 6.3 times of g-C<sub>3</sub>N<sub>4</sub> under visible light and simulated sunlight illumination, respectively. The enhanced photocatalytic activity may be owing to the porous nanobelt structure, enhanced absorbability of visible light, and surface vacant N-sites. It is expected that PN-g-C<sub>3</sub>N<sub>4</sub> would be a promising candidate for CO<sub>2</sub> photocatalytic conversion. |
