Novel S-Scheme Loofah Biochar/Mos2/G-C3n4 Heterojunctions with Efficient Photogenerated Carrier Separation and Transfer Capability: Effect, Mechanism and Application

Опубликована: Янв. 1, 2025

The construction of S-scheme heterojunctions has drawn widespread attention within the photocatalysis field due to their capacity for efficient separation photogenerated carriers, leading excellent photo-oxidation-reduction performance. Herein, a novel loofah biochar/MoS2/g-C3N4 (LB/MS/CN) heterojunction was successfully constructed by ultrasonication in 50% ethyl alcohol and heat treatment N2 atmosphere. Degradation experiments showed that 5% LB/MS/CN ternary photocatalyst had optimal photocatalytic efficiency (96.4%) degradation rhodamine B (RhB), reaction rate (k) this (0.05420 min-1) 5.4 times unmodified CN (0.01001 min-1). Ultraviolet-visible diffuse reflectance spectra, Mott-Schottky, free radical trapping suggested carriers were transferred through structure. Consequently, co-catalytic action LB synergistic impact structure between MS led reduced carrier recombination rate. Furthermore, outstanding stability maintain RhB performance under various environmental conditions (H2PO4-, NO3-, SO42-, HCO3-, NaCl, HA, real water), showing good promise practical applications. Thus, work provides possible strategy purifying wastewater visible light.

This study investigates the synthesis and evaluation of ZnO/g-C3N4 composites as efficient green catalysts for advanced oxidation processes (AOPs) targeting treatment contaminated water. The were synthesized using a ternary deep eutectic solvent physically–chemically characterized in detail, confirming their structural integrity successful synthesis. Photocatalytic, photo-Fenton- electro-Fenton-like experiments conducted Rhodamine B model contaminant to evaluate catalytic performance, reuse stability material. demonstrated excellent photocatalytic activity under LED light (395 nm), achieving pollutant removal around 59% 90 min. combined effect designed catalyst Fenton-like process, photo-Fenton-like significantly improved this close 95% 60 min due synergistic effects irradiation H2O2 activation. Finally, action process exhibited superior efficiency, 90% within 45 kinetic constants four times higher than those anodic alone. In addition, studies confirmed several cycles with high efficiencies, demonstrating viability long-term scalable water applications. These findings highlight potential through DES sustainable cost-effective alternative remediation technologies.
