title: Enhanced photo-Fenton-like process over Z-scheme CoFe2O4/g-C3N4Heterostructures under natural indoor light.
abstract: Low-cost catalysts with high activity and stability toward producing strongly oxidative species are extremely desirable, but their development still remains a big challenge. Here, we report a novel strategy for the synthesis of a magnetic CoFe2O4/C3N4hybrid via a simple self-assembly method. The CoFe2O4/C3N4was utilized as a photo-Fenton-like catalyst for degradation of organic dyes in the presence of H2O2under natural indoor light irradiation, a green and energy-saving approach for environmental cleaning. It was found the CoFe2O4/C3N4hybrid with a CoFe2O4: g-C3N4mass ratio of 2:1 can completely degrade Rhodamine B nearly 100 % within 210 min under room-light irradiation. The effects of the amount of H2O2(0.01-0.5 M), initial dye concentration (5-20 mg/L), solution pH (3.08-10.09), fulvic acid concentration (5-50 mg/L), different dyes and catalyst stability on the organic dye degradation were investigated. The introduction of CoFe2O4on g-C3N4produced an enhanced separation efficiency of photogenerated electron - hole pairs by a Z-scheme mechanism between the interfaces of g-C3N4and CoFe2O4, leading to an excellent activity as compared with either g-C3N4or CoFe2O4and their mixture. This study demonstrates an efficient way to construct the low-cost magnetic CoFe2O4/C3N4heterojunction as a typical Z-scheme system in environmental remediation.
