Description
Summary:A prominent issue is developing low-cost photocatalysts for water splitting hydrogen evolution. This work used a one-step microwave irradiation technique to make a copper ferrite incorporated graphitic carbon nitride (CuFe 2 O 4 /g-C 3 N 4 ) nanocomposite for use as a visible-light reactive photocatalyst. XRD, SEM, TEM, Raman, UV, PL, and BET were used to analyze the structural, morphological, optical and elemental composition of the composite photocatalysts. CuFe 2 O 4 was successfully incorporated in a g-C 3 N 4 matrix in this composite, resulting in a CuFe 2 O 4 /g-C 3 N 4 heterostructure that is substantially more efficient in photocatalytic H 2 generation by water splitting under visible light. The photocatalytic activity of CuFe 2 O 4 /g-C 3 N 4 composites is influenced by the CuFe 2 O 4 loading mass. The 15-CuFe 2 O 4 /g-C 3 N 4 composite, which includes 15% CuFe 2 O 4 , has a greater photocatalytic activity than the massive g-C 3 N 4 , with such a hydrogen evolution rate of 545 molh −1  g –1 , which really is 9.1-fold that of the massive g-C 3 N 4 . This paper proposes a new way for improving semiconductor-based heterostructures for solar fuel generation efficiency.
