g-C3N4/Carbon spheres composite for efficient photoreduction and simultaneous removal of chromium

Structural and chemical approaches to enhance the photo/electrocatalytic performance of carbon/g-C3N4 composite materials

“…Taking CS as the modification agent to tune g-C 3 N 4 is an available and low-cost strategy comparing to those routes with the above mentioned carbon materials. 68 In addition, the affluent surface hydroxyl group arising from the CS particles can enhance the electrostatic adsorption of target molecules and promote their binding the active site of CS/g-C 3 N 4 . With the assistance of those surface groups arise from CS, the hydrophilicity and dispersion of CS/ g-C 3 N 4 materials in the reaction system can also be improved.…”

Engineering of novel g-C3N4 photocatalyst using arc-discharge synthesized sphere-like carbon nanoparticles for enhanced photocatalytic activity

“…Some of the works focusing on sphere-like CNMs based on g-C 3 N 4 materials used in heterogenous photocatalysis are discussed here. Martinez J.P.C and group [13], have prepared g-C 3 N 4 / Carbon Sphere composite though hydrothermal synthesis having a visible region band gap for removal of Chromium [Cr (VI)] from water. After 4 hrs of light irradiation, 82% (100 ppm conc.)…”
