Utilizing artificial photosynthesis to activate the CO2 reduction reaction and convert it into useful chemicals could drive carbon recycling toward neutrality, effectively addressing global environmental and energy challenges in the long run. Carbon nitride is commonly used as a photocatalytic material, and the introduction of metallic element in the modification process increases the cost of the catalyst. Herein, Cu atoms are uniformly anchored on the surface of sulfur-containing carbon nitride through a convenient phytate acid-bridged approach, resulting in the novel composite catalyst of copper phytate and sulfur-containing carbon nitride (CuPA/SCN). The catalytic performance of CuPA/SCN has been greatly improved, with a CH3OH evolution rate of 11.87 μmol·g–1·h–1, which is nearly 10 times higher than that of SCN. Meanwhile, its excellent selectivity reaches up to 99.38%. Relevant tests and theoretical calculations reveal that CuPA can extract the electrons enriched at the S site and act as conductors. The surface electrons of carbon nitride are rearranged and enriched at S sites, transferred by Cu atoms, thereby promoting the continuous separation of photogenerated electrons and holes. The synergistic effect between CuPA and SCN prolongs charge recombination process, effectively improving the catalytic performance of the samples. This work enriches the complex catalysts of sulfur-containing carbon nitride for the catalytic conversion of carbon dioxide.

With the development of industry, agriculture, and aquaculture, excessive ammonia nitrogen mainly involving ionic ammonia (NH4+) and molecular ammonia (NH3) has inevitable access to the aquatic environment, posing a severe threat to water safety. Photocatalytic technology shows great advantages for ammonia nitrogen removal, such as its efficiency, reusability, low cost, and environmental friendliness. In this study, CP (g-C3N4/CoP) composite materials, which exhibited high-efficiency ammonia nitrogen removal, were synthesized through a simple self-assembly method. For the optimal CP-10 (10% CoP) samples, the removal rate of ammonia nitrogen reached up to 94.8% within 80 min under visible light illumination. In addition, the nitrogen selectivity S(N2) is about 60% for all oxidative products. The high performance of the CP-10 photocatalysts can be ascribed to the effective separation and transmission of electron–hole pairs caused by their heterogeneous structure. This research has significance for the application of photocatalysis for the remediation of ammonia nitrogen wastewater.
