Kinetics of the acid orange 7 degradation in the photocatalytic system of UV/H2O2/TS-1

Photocatalytic Performance and Degradation Pathway of Rhodamine B with TS-1/C3N4 Composite under Visible Light

“…Although the specific surface areas of the materials vary greatly (Figure 5a), they show sufficient adsorption capacity of RhB before irradiation. Under visible light irradiation, RhB concentration decreases by only 20% within 60 min without catalyst (curve III in Figure 7a), which is attributed to the degradation in the presence of visible light and H 2 O 2 [50]. H 2 O 2 is a kind of reactant to produce the active species (e.g., ·OH) under irradiation, and ·OH can accelerate the oxidation of organic compounds [51].…”

Photocatalytic degradation of ofloxacin antibiotic wastewater using TS-1/C3N4 composite photocatalyst: Reaction performance optimisation and estimation of wastewater component synergistic effect by artificial neural network and genetic algorithm

“…Therefore, a comprehensive study including the enhancement of photocatalytic activity, optimization of operational parameters and prediction of synergistic effects of wastewater components was carried out in this work. Firstly, titanium silicon molecular sieve (TS-1) was used to synthesize TS-1 loaded C 3 N 4 (TS-1/C 3 N 4 ) composite because of its response to ultraviolet light, large specific surface area and strong adsorption capability [26]. The effect of experimental parameters (TS-1 loading, catalyst dose and luminous power density (LPD)) and wastewater constituents (such as cations, metal ions and anions) on RE was systematically investigated.…”
