A Z-scheme 2D/0D ZnIn₂S₄/ZnO heterostructure for efficient photocatalytic degradation of tetracycline: energy band engineering and morphology modulation

Abstract

Semiconductor-based photocatalysis is of great practical significance to degrade persistent organic pollutants (POPs). However, it is still in challenges and always in pursuit to construct a photocatalyst system with efficient...

Accelerated sonochemical fabrication of MIn2S4 (M = Zn, Mg, Ni, Co) for ultra-high photocatalytic hydrogen peroxide production

“…As shown in Fig. 2 (f) and 2(h), the HRTEM image clearly shows that the lattice fringes have spacings of 0.41 nm and 0.32 nm, matching well with the results of the (0 0 6) and (1 0 2) planes of ZnIn 2 S 4 , respectively [10] , [35] . In sonochemical synthesis, the localized high temperature and pressure resulting from the collapse of acoustic bubbles accelerate the dissolution of precursors.…”

“…Well-resolved peaks appear at 21.2°, 27.6°, 30.5°, 47.4°, 52.2°, and 55.5°, being agree with the (0 0 6), (1 0 2), (1 0 4), (1 1 0), (1 1 6), and (0 2 2) that of ZnIn 2 S 4 , respectively (#JCPDS Card No. 65-2023) [35] . Fig.…”
