Photoelectrochemical (PEC) CO<sub>2</sub> reduction is hindered by sluggish kinetics, poor selectivity, and competing hydrogen evolution.
Description
Herein, a g-C<sub>3</sub>N<sub>4</sub>/Ag-melamine coordination polymer (AgM-CP) heterostructure is developed to enhance CO<sub>2</sub> conversion performance. Incorporation of Ag modulates the electronic structure, improves light absorption, and promotes selective syngas production without forming liquid byproducts.
The catalyst achieves a total current density of 52 mA cm<sup>–2</sup>, with ca. 15 mA cm<sup>–2</sup> attributed to CO<sub>2</sub> reduction at −1.48 V vs RHE. Under illumination, a maximum CO generation rate of (269.0 ± 13.4) μmolcm<sup>–2</sup>h<sup>–1</sup> is achieved, with a higher CO/H<sub>2</sub> ratio at −0.88 V, which declines at more negative potentials. The <i>I</i>–<i>V</i> curve for g-AM collected under chopped illumination exhibits a moderate photocurrent density of 0.07 mA cm<sup>–2</sup> at −0.88 V vs RHE.

Reduction of Ag<sup>+</sup> partially consumes electrons, slightly lowering Faradaic efficiency. The g-AM exhibits impressive applied bias photon-to-current efficiency of ca. (1.75 ± 0.1) % at −1.08 V vs RHE. Interfacial wettability and local CO<sub>2</sub>/H<sub>2</sub>O concentrations govern activity; Tafel analysis shows first electron transfer limits, while low charge-transfer resistance enhances CO production at lower bias.
