Dr. Xiaoyan Published article on Journal of Colloid and Interface Science with the title of "Hierarchical Sb2S3/ZnIn2S4 core-shell heterostructure for highly efficient photocatalytic hydrogen production and pollutant degradation"
Abstract: In this work, a novel hierarchical 1D/2D core/shell Sb2S3-ZnIn2S4 (SB-ZIS) heterostructure with highly efficient photocatalytic activities for both hydrogen production from water and organic pollutant degradation was designed and fabricated via a simple one-step hydrothermal method. The photocatalytic H2 production rate of optimal SB-ZIS-2 sample was about 12.24 times as large as that of pure ZnIn2S4. The apparent quantum efficiency (AQE) at 420 nm was up to 3.8%. In addition, the highest rate constant for TCH removal was 20.3 and 2.89 times larger than those of pure Sb2S3 and Znln2S4, respectively. The possible reaction routes of TCH and the photocatalytic reaction mechanism of SB-ZIS sample were also discussed in detail. This work will provide some useful information for the development of dual-functional Sb2S3-based type I core-shell heterostructure with an efficient photocatalytic activity for solving environmental pollution and producing clean hydrogen energy.
