Activation of peroxymonosulfate by single atom Co-N-C catalysts for high-efficient removal of chloroquine phosphate via non-radical pathways: Electron-transfer mechanism

Effective degradation of COVID-19 related drugs by biochar-supported red mud catalyst activated persulfate process: Mechanism and pathway

“…It was found that RM-BC/PS system could achieve high removal rates for these drugs within a relatively shorter reaction time. In addition, ACV is more resistant to degrade than HCQ and CQ ( Bensalah et al, 2020 ; Hu et al, 2014 ; Peng et al, 2022 ), which is consistent with this study. Comparison of RM-BC with other RM-biochar or RM-related catalysts on drug degradation was shown in Table S2 .…”

Construction of a Z-scheme g-C3N4/NBGO/BiVO4 heterostructure with visible-light driven photocatalytic degradation of tetracycline: efficiency, reaction pathway and mechanism

“…In recent years, semiconductor photocatalysis degradation technology has gained widespread interest as a green and environmentally friendly way to degrade organic pollutants in water. 12–15 Graphitic nitrogen carbide (g-C 3 N 4 , CN) is a typical n-type visible light photocatalyst that has gained extensive interest in photocatalysis due to its narrow band gap, wide visible light response, high thermochemical stability, outstanding photoelectrochemical properties, low cost, and ease of large-scale preparation. 2,16–18 However, the efficiency of a single semiconductor was restricted due to the rapid photogenerated electron (e − )–hole (h + ) recombination rate and the low visible light response efficiency.…”

3D/2D Heterojunction Fabricated from RuS2 Nanospheres Encapsulated in Polymeric Carbon Nitride Nanosheets for Selective Photocatalytic CO2 Reduction to CO

“…The EIS Nyquist plot of 5%-RuS 2 /PCN shows a smaller radius, indicating that it has a lower interface resistance and higher transfer capacity than PCN. 40,41 Moreover, based on the obtained equivalent circuit from EIS Nyquist plots (Figure S4), the charge transfer resistance (R ct ) value of 5%-RuS 2 /PCN (785.7 Ω) is much lower than that of PCN (4558 Ω), indicating that its charge transfer rate has increased. By further fitting the cyclic voltammetry (CV) curves at different scan rates (Figure S3), Figure 3e shows that the double-layer capacitance (C dl ) of 5%-RuS 2 /PCN (0.173 mF cm −2 ) reaches 3.6 times as large as that of PCN (0.048 mF cm −2 ), which indicates that the former has a higher electrochemically active surface area (ECSA) than that of the latter owing to the linear positive relativity between C dl and ECSA.…”
