In-situ formed N-doped bamboo-like carbon nanotubes encapsulated with Fe nanoparticles supported by biochar as highly efficient catalyst for activation of persulfate (PS) toward degradation of organic pollutants

In this study, N-doped bamboo-like carbon nanotubes encapsulated with Fe nanoparticles (Fe NPs) on the surface of soybean dregs-derived biochar ([email protected] − BC) was synthesized via a low-cost and facile strategy. The unique composites behaved as efficient catalysts for the degradation of various organic pollutants by the activation of persulfate (PS). Under the conditions of [PS] = 5 mM, [RhB] = 20 mg/L, [[email protected]] = 1.0 g/L, pH...
