Abstract
The novel ternary Fe 3 N/Fe 2 O 3 /C 3 N 4 photocatalyst was prepared by thermal pyrolysis of potassium ferricyanide in melamine. The structural, morphological and physico-chemical properties of the photocatalyst were characterized by a multi-technique approach. Photocatalytic experiments supported that 0.04 g of the photocatalyst was able to totally remove 5 ppm of rhodamine B (RhB) solution under acidic condition with the rate constant of 0.1 min −1 in less than 30 min. According to spin-trapping ESR analysis, • OH radicals play a key role in the RhB photodegradation implying Z-scheme mechanism is applicable to our system. Moreover, the evolution rate of CO and CH 4 over the photocatalyst was 8.03 and 1.6 μmol g −1 h −1 , respectively, which was much higher than the reference photocatalysts under the same conditions. The enhanced photocatalytic performance of this system is attributed to the unique ternary heterojunction between the interfaces of g-C 3 N 4 , Fe 3 N and Fe 2 O 3 , which effectively suppressed the charge carriers recombination. • A novel ternary Fe 3 N/Fe 2 O 3 /C 3 N 4 photocatalyst was prepared from cheap raw materials. • The interfacial Fe 3 N regions act as electron mediator and bandgap modifier. • The mechanism of RhB photodegradation was well discussed based on EPR experiments. • The ternary Fe 3 N/Fe 2 O 3 /C 3 N 4 photocatalyst showed efficient photocatalytic CH 4 evolution performance.
