Cobalt-doped graphitic carbon nitride with enhanced peroxidase-like activity for wastewater treatment

Abstract

The peroxidase-like activity of graphitic carbon nitride (g-C3N4) is dramatically increased by a small cobalt doping. The cobalt-doped g-C3N4 was used for wastewater treatment, exhibiting much higher degradation rate than that of pure g-C3N4.

Nanozyme applications in biology and medicine: an overview

“…Also, ferro-carbon may accelerate cell cycle and proliferation, which may be mediated by the free iron (Fe), released from lysosomal degradation and involves the alteration of Fe on the expression of the protein regulators of the cell cycle [47]. Also, some of the medical applications including Transplant monitoring in a study for therapy of diabetes via transplant pancreas and monitoring by iron oxide nanoparticles for tissue transplantation [48]. Targeted cell death of tumour cells through controlled heating of the damaged tissue via Engineering the magnetic nanoparticles for Hyperthermia is based on magnetic nanoparticle [49].…”

In situ synthesis of molybdenum carbide/N-doped carbon hybrids as an efficient hydrogen-evolution electrocatalyst

“…Electrochemical experiments were performed by a threeelectrode system with catalysts modied GCE as the working electrode, a graphite rod as the counter electrode and a saturated Ag/AgCl as the reference electrode at 25 C ) and n was the moles of the metal atom on the electrode based on the loading mass and molecular weight of the coated catalysts. The electrochemically active surface areas (ECSA) of the electrocatalysts were calculated by the doublelayer capacitor with the reported electrochemical method.…”

“…During the rst annealing at 400 C, the pyrolysis of urea could result in g-C 3 N 4 material, which had a stacked 2D lamellar structure similar to graphite. 25,26 And during the second annealing, the pyrolysis g-C 3 N 4 and formed molybdenum oxide from the rst annealing led to the formation of graphitic carbon, because Mo species could promote the catalytic growth of carbon from the decomposed intermediates of g-C 3 N 4 .…”
