Single atom Fe-dispersed graphitic carbon nitride (g-C3N4) as a highly efficient peroxymonosulfate photocatalytic activator for sulfamethoxazole degradation

Gang Zhao et al.

Summary: A highly efficient single atom Fe-dispersed catalyst with Fe-N-4 coordination structure was synthesized for peroxymonosulfate (PMS) activation and sulfamethoxazole (SMX) degradation. The catalyst showed excellent performance in PMS activation and SMX removal, with a high turnover efficiency and good stability. Identification of reaction active species and proposed degradation mechanism for SMX provide valuable insights for sulfate radical-based advanced oxidation processes.

Synergistic effect of Ru-N4 sites and Cu-N3 sites in carbon nitride for highly selective photocatalytic reduction of CO2 to methane

Lei Zeng et al.

Summary: In this work, ruthenium and copper single atoms were successfully incorporated into polymeric carbon nitride through a preassembly-coprecipitation-pyrolysis process. The resulting photocatalyst exhibited high selectivity for methane production during the photocatalytic reduction of CO2 under visible-light irradiation. The presence of Ru-N4 and Cu-N3 sites in the catalyst's structure facilitates the electron-hole pair separation and CO2 hydrogenation, leading to enhanced CH4 production.

Advantageous roles of phosphate decorated octahedral CeO2 {111}/g-C3N4 in boosting photocatalytic CO2 reduction: Charge transfer bridge and Lewis basic site

Wanqin Li et al.

Summary: The P-CeO2/g-C3N4 photocatalyst coupling phosphate modified octahedral CeO2 {111} surface with gC(3)N(4) showed superior CO2 reduction activity due to efficient charge transfer and increased oxygen-containing functional groups on the surface. The interfacial electrons donated from g-C3N4 to CeO2 through the PO43- bridge led to Z-scheme formation, facilitating rapid photo-generated charge transfer and CO2 activation. This synergistic interaction of charge-transfer channel and abundant active sites makes P-CeO2/g-C3N4 a potential photocatalyst for CO2 reduction.

Thermal coupled photocatalysis over Pt/g-C3N4 for selectively reducing CO2 to CH4 via cooperation of the electronic metal-support interaction effect and the oxidation state of Pt

Ning Sun et al.

Summary: Pt nanoparticle-loaded g-C3N4 was prepared for selectively reducing CO2 to CH4 with H2O by thermal coupled photocatalysis.

In situ Irradiated XPS Investigation on S-Scheme TiO2@ZnIn2S4 Photocatalyst for Efficient Photocatalytic CO2 Reduction

Libo Wang et al.

Summary: Efficient hierarchical photocatalysts, such as the S-scheme core-shell TiO2@ZnIn2S4 heterojunction, have gained attention for photocatalytic CO2 reduction. The improved performance is attributed to the inhibited recombination of photogenerated charge carriers induced by the S-scheme heterojunction, as well as the large specific surface areas and abundant active sites. In situ irradiated X-ray photoelectron spectroscopy, work function calculation, and electron paramagnetic resonance measurements confirm the S-scheme photogenerated charge transfer mechanism.
