Construction of core-shell g-C3N4@ZnIn2S4 hierarchical hollow heterostructure for enhanced photocatalytic activity under visible light irradiation

Facile preparation of a Co3O4/Mn0.5Cd0.5S heterojunction with highly efficient photocatalytic H2 production

“…The photoinduced e − and h + separation properties of the catalyst were represented by PL, TRPL, photocurrent and EIS. 19,43 It can be seen from the i – t diagram of the photocurrent (Fig. 6a) that the photocurrent response of COMCS- x is stronger than that of MCS, and Co 3 O 4 has no photoresponse.…”

“…Metal sulfides are widely used for photocatalytic hydrogen precipitation because of their narrow band gap and applicable energy band structure. 14 Among them, polysulfide photocatalytic materials are of wide interest due to their superb visible light response capability and tunable energy band structure, such as Zn x Cd 1− x S, 15 Cu x Cd 1− x S, 16 Mn x Cd 1− x S, 17 (CdS) x (ZnTe) 1− x , 18 ZnIn 2 S 4 , 19 etc. Mn x Cd 1− x S has been widely applied for hydrogen production by photocatalytic decomposition of water on account of its characteristics of changing the energy band structure by changing the x -value, and it shows excellent electron transfer efficiency and considerable light absorption ability and was first reported in 2010.…”

Synthesis of g-C3N4@ZnIn2S4 Heterostructures with Extremely High Photocatalytic Hydrogen Production and Reusability

“…The Fourier Transform Infrared spectroscopy (FTIR) spectra of g-C 3 N 4 nanostructures and g-C 3 N 4 @ZnIn 2 S 4 heterostructures with 0.01 g g-C 3 N 4 nanostructures are depicted in Figure 4c. In these FTIR spectra, a distinct peak at 811 cm −1 originates from the characteristic breathing vibration of the triazine ring in g-C 3 N 4 [37,44]. Additionally, absorption bands within the 1200-1640 cm −1 range signify the stretching vibration modes of the C, N-heterocyclic groups present in g-C 3 N 4 [45,46].…”
