“…Based on the above experimental results and previously reported works, we propose the possible photocatalytic mechanism of carbon dioxide transformation. − As shown in Figure , the excellent catalytic activity and selectivity can be attributed to the collaborative impact of sulfur atoms and the CuPA complex. On the one hand, the S atoms rearrange the surface charges of the samples and make it easier to gather photogenerated electrons.…”

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.

“…Among them, in situ FTIR and Raman are widely used. [160,[224][225][226][227][228][229] For in-stance, in the process of H 2 S treatment, in situ ATR-FTIR can identify the signals related to sulfur-containing oxides. However, the detection of S n 2− is difficult due to the negligible S-S bond signal in ATR-FTIR.…”

Hydrogen is one of the most important energy alternatives to conventional fossil‐based fuel. Solar energy based photocatalytic hydrogen evolution (PHE) is a salient approach to produce hydrogen fuel but its efficiency is generally limited by the sluggish and energy‐unfavorable oxidation reaction. Meanwhile, waste treatment has become a worldwide problem and clean treatment is highly demanded to avoid the vast greenhouse emission currently. Inspiringly, PHE can be effectively coupled with the favorable photooxidation of many wastes, which kills two birds with one stone. In this review, the recent progress in PHE coupled with waste treatment is presented, where typical solid, liquid, and gas wastes have been briefly discussed. Focusing on the understanding of complicated reaction mechanism and the revelation of oxidation products, the cutting‐edge techniques for photophysics and surface chemistry characterization have been analyzed, which are imperative to facilitate the following investigation. Finally, the developing trend and existing issues in current research are also discussed in detail so that a holistic blueprint of PHE coupled with waste treatment can be portrayed to accelerate their application in a realistic world.
