Summary: The ideal photocatalyst for photocatalytic water splitting should have strong light absorption, fast charge separation/transfer ability, and abundant active sites. Heteroatom doping offers a promising approach for optimizing photocatalytic activity. In this study, boron (B) and sulfur (S) dopants were simultaneously introduced into graphitic carbon nitride (g-C3N4) nanotubes using a supramolecular self-assembly strategy. The developed B and S co-doped g-C3N4 nanotubes exhibited outstanding photocatalytic performance, achieving a conversion rate of H2O to H-2 of 9.321 mmol g(-1)h(-1), with an external quantum efficiency of 5.3% under irradiation at λ = 420 nm. The introduction of B dopants facilitated H2O adsorption and interatomic electron transfer, while S dopants promoted the oxidation ability of g-C3N4 and inhibited recombination. Furthermore, the simultaneous introduction of B and S optimized the electronic and energy level structures of g-C3N4 for efficient charge transfer, ultimately maximizing photocatalytic performance.

Summary: This study proposes a correction algorithm based on analyzing steam condensation locations to solve the problem of large errors in calculating the heat transfer of air-cooling condenser (ACC) in Fluent. By building an accurate geometric model of the ACC and simplifying the heat-sinking tube bundle using radiator boundary conditions, Fluent software was used to calculate the heat transfer of the ACC under winter operating conditions. The calculated results were then corrected using the proposed algorithm, reducing the errors from 4.20% to 36.98% to 0.01% to 1.79%. The correction algorithm improves the accuracy by considering the steam condensation positions and can be applied to indirect air-cooling generator sets for anti-freezing guidance.

Summary: Plastic pollution is a serious environmental problem, and the inert nature of plastic makes it difficult to degrade. In this study, supercritical CO2 (Sc-CO2) assisted by NaOH/HCl solution was used to degrade polystyrene (PS) plastic under mild conditions. The factors affecting PS degradation efficiency were found to be reaction temperature, reaction time, and NaOH/HCl concentration. The use of Sc-CO2 created a homogeneous environment, promoting the degradation of PS. Furthermore, the addition of NaOH/HCl solution improved the solubility of PS in Sc-CO2 and reduced the activation energy of the reaction, leading to enhanced degradation efficiency. Overall, degrading PS in Sc-CO2 with the assistance of a base/acid solution is feasible and provides a reference for the future disposal of waste plastics.
