Noble metal-free porphyrin covalent organic framework layer for CO<sub>2</sub> photoreduction to CO
The presence of greenhouse CO<sub>2</sub> gas in the atmosphere causes serious environmental issues. Consequently, the development of photocatalysts for reducing CO<sub>2</sub> is essential for mimicking artificial photosynthesis. In this study, we prepared a 5,15-di(4-aminophenty)-10,20-diphentyporphyrin copper (CuDAPP)-1,3,5-triformylphloroglucinol (TP)-covalent organic framework (COF) layer on a glass sheet <i>via</i> a layer-by-layer (LBL) method. The 2D CuDAPP-TP-COF layer was used as a photocatalyst for CO<sub>2</sub> reduction, and it demonstrated excellent photocatalytic activity under gas-solid conditions without sacrificial reagents, noble metals, or photosensitisers. The CO production yield was 282.6 μmol g<sup>-1</sup> under visible-light irradiation for 6 h, outperforming the raw material CuDAPP and a mixture of CuDAPP and TP, indicating a high application potential of the 2D porphyrin COF layer material in photocatalytic CO<sub>2</sub> reduction.
