Using oxygen reduction for the photocatalytic production of hydrogen peroxide (H2O2) has been considered a green and sustainable route. In present study, to achieve high efficiency, graphitic carbon nitride (g-C3N4) was obtained using thermal polymerization from bi-component precursor then assembled with cellulose nanofibers. It found that small quantity nanofibers generates fibers upon pyrolys...

Transition metal phosphides have been recognized as efficient co-catalysts to boost the activity of semiconductor photocatalysts. However, a rigorous and quantitative understanding is still be developed about how transition influence photoexcited electron dynamics. Here, we present nanosecond time-resolved transient absorption spectroscopy (TAS) study dynamics in carbon nitrides (g-C3N4) before...

Graphitic carbon nitride (g-C3N4) is a metal-free heterogeneous catalyst that has attracted attention because of its good chemical stability, cost-effectiveness, and environmental friendliness. In the work presented herein, F,O,S-codoped was synthesized by heating mixture melamine cyanurate trifluoromethanesulfonic acid at 550 °C for 50 min. The obtained product characterized transmission elect...

Carbon quantum dots (CDs) are a fascinating class of carbon nanomaterials (less than 10 nm in size) with unique optical, electrical, and physicochemical properties. In addition to these properties, CQDs exhibit the desired advantages aqueous stability, low toxicity, high surface area, economic feasibility, chemical inertness, highly tunable photoluminescence behaviour. Recently, graphitic nitri...

Dispersion of 2D carbon nitride (C3N4) nanosheets into a nickel phosphorous (NiP) matrix was successfully achieved by ultrasonication during the electroless plating of NiP from an acidic bath. The morphology and thickness, elemental analysis, phases, roughness, and wettability for as-plated and heat-treated nanocomposite were determined by scanning electron microscopy, energy-dispersive X-ray s...

Ultrathin metal-free g-C3N4 nanosheets with intrinsic room temperature ferromagnetism were synthesized by heating urea in an airtight container at different temperatures. Results indicate that the samples' saturation magnetization increases with the carbon defect concentration, revealing its carbon defect related ferromagnetism. Moreover, we further confirmed the defect induced ferromagnetic na...

A series of carbon dots (CDs) modified g-C3N4 (xCDs/g-C3N4; x = 0.5, 1.0, and 1.5 mL CDs solution) was synthesized via the microwave-assisted hydrothermal synthesis method for photooxidation bisphenol-A (BPA) under visible light irradiation.
