Nongraphitic Carbon Nitride Melem Oligomer Nanosheets for Photocatalytic Degradation of Organic Pollutants

“…In recent years, energy shortages and environmental pollution have become the focus of world attention. − Photocatalysis is a conceptually simple and environmentally sustainable method that has attracted considerable interest from researchers in the treatment of organic pollutants in H 2 O because of its use of light as a renewable energy source. − Semiconductor photocatalysis is an effective method to remove organic pollutants from H 2 O. , Graphite carbon nitride (g-C 3 N 4 ) is a promising metal-free, visible-light-responsive photocatalyst that has attracted more and more attention in the field of photocatalytic hydrogen evolution and pollutant removal because of its unique optical, electronic, and good structural stability. − However, the high recombination rate, low specific surface area, and low electrical conductivity of charge carriers limit the activity of g-C 3 N 4 synthesized by traditional methods. , In order to overcome the inherent limitations of intrinsic carbon nitride materials, many studies have focused on the modification and improvement of the photocatalytic performance of highly polymerized melon (g-C 3 N 4 ) generated at about 550 °C, − while neglecting the rich diversity of other polymerized carbon nitride materials. In particular, there is a lack of knowledge about the melem oligomeric phase obtained at pyrolysis temperatures below 500 °C.…”

A novel full solar light spectrum responsive antimicrobial agent of WS2 quantum dots for photocatalytic wound healing therapy

“…Recently, most photocatalytic agents have been used against bacteria by reacting with overexpressed H 2 O 2 in the BME to produce large amounts of ˙OH. 33 To further investigate the full-spectrum responsive catalytic behavior of WS 2 QDs, we examined whether the WS 2 QDs could facilitate the splitting of H 2 O 2 into ˙OH and deplete GSH under full spectrum irradiation to improve the antibacterial activity for synergistic wound therapy and healing. Firstly, the POD-like catalysis of the prepared WS 2 QDs was investigated under different reaction conditions by using TMB as a ˙OH probe.…”

Mo-Based Heterogeneous Interface and Sulfur Vacancy Synergistic Effect Enhances the Fenton-like Catalytic Performance for Organic Pollutant Degradation

“…The H 2 O 2 concentration was determined using a titanium potassium oxalate method with a UV–vis spectrophotometer (Saimerfei Evolution 201 UV–vis). , In a typical method, a certain amount of solution to be tested was added to the colorimetric tube, and 500 μL of 3 mol/L H 2 SO 4 solution and 500 μL of 0.05 mol/L potassium titanate solution were subsequently added. After aloowing it to stand for 8 min, the absorbance of the solution was measured at 385 nm using a UV–vis spectrophotometer.…”
