This work demonstrated that Enteromorpha biochar with introduced iron (SFB900-3) could activate peroxymonosulfate (PMS) efficiently for NTP remediation. It removed 83.9%–95.1% of NTP in 60 min under a wide pH range from 3.15 to 8.95. Density functional theory (DFT) calculations revealed the synergistic relationship between internal Fe single atoms and introduced Fe compounds—Fe3C. The adsorption capacity of SFB900-3 for persulfate improved from −0.953 eV to −4.214 eV, and the Bader charge analysis showed that Fe atoms as active sites (0.658 e) enhanced the adsorption capacity more than carbon (0.050 e). Moreover, the energy barrier for PMS dissociation reduced from 0.072 eV to −5.372 eV due to the longer length of O–O bond under the synergistic effect of Fe single atom and Fe3C which increased from 1.467 Å to 3.890 Å. The quenching experiment confirmed that 1O2 was the main active substance in NTP degradation and its contribution rate was 88.2%, which was further verified by EPR detection. The effect factor experiments proved that the SFB900-3/PMS system had stable and efficient activity for NTP removal, which remained at 73.6% removal rate after three rounds of tests. This work provided novel guidance for constructing efficient and stable biochar-based materials for organic pollutant remediation. Graphical Abstract

A series of nickel-doped copper tungstate/oxygen-rich TiO 2 heterojunction-constructed composites of xNi-CuWO 4 /OTiO 2 were successfully prepared to demonstrate the enhancement of the visible-light photoactivity through promoting the photogenerated charge carrier separation efficiency. Of all these composites, 0.2Ni-CuWO 4 /OTiO 2 exhibits excellent and stable visible light photoactivity for the photooxidative coupling of benzylamine to the corresponding N-benzyl-1-phenymethanimine (BPMI) in air atmosphere. The conversion of benzylamine and the selectivity to BPMI reach 97% and 99%, respectively. The catalyst shows good cyclability with the conversion of benzylamine decreasing just by 22% after being repeated six times with the well-maintained selectivity of BPMI. The composite also exhibits excellent photo-bactericidal ability, which greatly inhibits the reproducing of both the Gram-positive bacteria (e.g., S. epidermidis) and Gram-negative bacteria (e.g., E. coli).

“…[166,167] The effect of polymerization can be explained in two ways: on one side, the higher the degree of polymerization, the better the crystallinity of the resultant product, which consequently extends the delocalization of the π-electron, reducing the band gap and promotes charge carriers smoother movement. [168,169] Such phenomena are highly beneficial for photocatalytic applications. On the other side, reducing the extent of polymerization results in an increase in the number of defective sites such as NH 2 , which are considered the true active sites where photocatalytic reactions occur.…”

A Comprehensive Review on Graphitic Carbon Nitride for Carbon Dioxide Photoreduction

2022

View full text Add to dashboard Cite

Inspired by natural photosynthesis, harnessing the wide range of natural solar energy and utilizing appropriate semiconductor‐based catalysts to convert carbon dioxide into beneficial energy species, for example, CO, CH4, HCOOH, and CH3COH have been shown to be a sustainable and more environmentally friendly approach. Graphitic carbon nitride (g‐C3N4) has been regarded as a highly effective photocatalyst for the CO2 reduction reaction, owing to its cost‐effectiveness, high thermal and chemical stability, visible light absorption capability, and low toxicity. However, weaker electrical conductivity, fast recombination rate, smaller visible light absorption window, and reduced surface area make this catalytic material unsuitable for commercial photocatalytic applications. Therefore, certain procedures, including elemental doping, structural modulation, functional group adjustment of g‐C3N4, the addition of metal complex motif, and others, may be used to improve its photocatalytic activity towards effective CO2 reduction. This review has investigated the scientific community's perspectives on synthetic pathways and material optimization approaches used to increase the selectivity and efficiency of the g‐C3N4‐based hybrid structures, as well as their benefits and drawbacks on photocatalytic CO2 reduction. Finally, the review concludes a comparative discussion and presents a promising picture of the future scope of the improvements.
