Ag modified ZnS for photocatalytic water pollutants degradation: Influence of metal loading and preparation method

“…Heterogeneous photocatalysis is a promising approach to protect the aquatic environment due to its ability to remove organic pollutants in water [1]. In the past two decades, many semiconducting oxides and sulfides, such as TiO 2 , ZnO, WO 3 , SrTiO 3 , ZrO 2 , ZnS, CdS, CuS were applied as photocatalysts for environmental control technology and also for a wide range of chemical reactions [2][3][4][5][6]. Among them, ZnS is an important II-VI group semiconductor existing in two main crystalline phases: -phase (hexagonal wurtzite structure) and -phase (cubic sphalerite structure) [7].…”

One-Step Low Temperature Hydrothermal Synthesis of Flexible TiO2/PVDF@MoS2 Core-Shell Heterostructured Fibers for Visible-Light-Driven Photocatalysis and Self-Cleaning

“…Therefore, the key for preparation of a highly active and recyclable TiO 2 -based photocatalyst is to find a strategy for inhibiting photo-generated electron-hole recombination, narrowing the band gap and easy recovery and recycle. To this end, many strategies have been developed, one of which is the composition of narrow band gap semiconductors to TiO 2 to form a heterogeneous structure [4,5,6]. On the one hand, the composition of narrow band gap semiconductors can improve the photocatalytic activity of TiO 2 -based photocatalysts by expanding their light capture window to the visible range [7].…”
