In this study, a novel g-CN-based ternary heterojunction was rationally designed and constructed by the growth of ZnInS nanosheets and CdS nanoparticles onto the g-CN nanosheets using a facile two-step oil-bath method. Through optimizing the proportion of ZnInS and CdS component, g-CN nanosheets coupled with ZnInS nanosheets and CdS nanoparticles (denoted as CdS/ZnInS/g-CN) exhibited obviously higher photocatalytic properties for RhB removal than the single-component and dual-component systems. Among the as-obtained ternary photocatalysts, it was found that the ternary CdS/ZnInS/g-CN-0.2 photocatalyst displayed the optimum photocatalytic property (96%) within a short time (30 min), which was almost 27.42 and 1.17 times higher than that of pure g-CN and binary ZnInS/g-CN-0.7 composite. The excellent activity of the ternary CdS/ZnInS/g-CN heterostructure is assigned to the synergetic effects of CdS nanoparticles, ZnInS nanosheets and g-CN nanosheets, which not only broaden the visible-light absorption range, but also improve the charge mobility and separation rate, thus boosting the visible-light-driven photocatalytic property of g-CN.

Exploiting innovative sensing mechanisms and their rational implementation for selective and sensitive detection has recently become one of the mainstream research directions of photoelectrochemical (PEC) bioanalysis. In contrast to existing conventional strategies, this study presents a new liposome-mediated method via combining ZnInS nanosheets (ZIS NSs) with SnS to form a ZIS NSs/SnS type-I heterojunction on fluorine-doped tin oxide (FTO) electrodes for highly sensitive PEC immunoassays. Specifically, alkaline phosphatase (ALP)-encapsulated liposomes were confined within 96-well plates by sandwich immunorecognition and subsequently subjected to lysis treatment.
