Single-atom Nb anchored on graphitic carbon nitride for boosting electron transfer towards improved photocatalytic performance

Investigation of the structural, electronic, mechanical, and optical properties of NaXCl3 (X = Be, Mg) using density functional theory

“…In perovskite compounds, the X site is typically occupied by either oxide or halide ions. [1][2][3] Perovskites are a category of compounds known for their distinct crystal structure and remarkable physical and chemical properties. 4,5 These materials have attracted signicant attention from researchers due to their exible structure and exceptional electromagnetic, elastic, thermal, and electrical behaviors.…”

Preparation of Oxygen-Doping Nongraphitic Carbon Nitride via Efficiency Exfoliation for the Application of Photocatalytic Degradation

“…The small amount of C–O bonds present in the original LCN is due to oxygen in air during the calcination process. It is obvious seen that the content of C–O bonds in E-OLCN is significantly higher than that of LCN, indicating that there are more C–O bonds in E-OLCN. , This may lead to a shift in the center of the peaks; however, the characteristic peak of E-OLCN at about 531.4 eV still represents C–O bond according to the literature . For XPS spectra of C 1s in Figure c, the peaks at 288.9 and 288.1 eV correspond to C–O and NC–N, respectively, and there is a significant increase in C–O for E-OLCN compared to LCN, which is consistent with the results for O 1s, but a slight decrease in NC–N.…”

“…21,38 This may lead to a shift in the center of the peaks; however, the characteristic peak of E-OLCN at about 531.4 eV still represents C−O bond according to the literature. 39 For XPS spectra of C 1s in Figure 3c, the peaks at 288.9 and 288. In order to obtain more evidence of the effect of the O doping of E-OLCN, EPR was performed to detect the spin states of unpaired electrons, as shown in Figure 3e.…”

Strengthened H2O adsorption and photogenerated carrier separation: surface C-coupled hydroxylation of g-C3N4 photocatalysts for efficient H2 production

“…13,14 However, the H 2 evolution rate of pristine g-C 3 N 4 is constrained due to intrinsic restrictions of the visible-light response range and the low separation rate of carriers. [15][16][17] For enhancing the H 2 evolution rate, many modication ways are explored, such as ion doping, [18][19][20] structural tailoring, 21 and defect engineering 22,23 successfully. It was reported that most pristine g-C 3 N 4 modication studies are concerned with the heterojunction engineering of g-C 3 N 4 photocatalytic systems for H 2 production.…”
