Increasing H₂production on Zn_xIn_yS_zunder visible lightviacomposition modulation and CoS catalysis

Abstract

Zinc indium sulfides (ZnxIn2Sx+3, x = 1-5) are known to initiate H2 production under visible light, among which ZnIn2S4 is the most active with triethanolamine (TEOA) as sacrifice. In this...

Dispersing agglomerated Zn4In2S7 on g-C3N4 nanosheets to form a 2D/2D S-scheme heterojunction for highly selective photocatalytic cleavage of lignin models

“…14 Among these, ZnIn 2 S 4 has found extensive use in photocatalysis research, 15 while Zn 4 In 2 S 7 modifies the stoichiometry of ZnIn 2 S 4 to tailor the band gap, resulting in improved lignin depolymerization capabilities. 16 Nevertheless, the photocorrosion of sulfides is a difficult problem to overcome. 17 As the proportion of Zn 2+ increases, the layered structure of Zn 4 In 2 S 7 becomes denser, mainly attributed to the smaller ionic radius of Zn 2+ in comparison with In 3+ .…”
