Ultrathin layered MoS₂ nanosheets with rich active sites for enhanced visible light photocatalytic activity

Abstract

Edge-rich active sites of ultrathin layered molybdenum disulphide (MoS2) nanosheets were synthesized by a hydrothermal method.

RETRACTED ARTICLE: Cost effective liquid phase exfoliation of MoS2 nanosheets and photocatalytic activity for wastewater treatment enforced by visible light

“…The degradation of the methylene blue is due to the photocatalytic activity via efficient charge separation in MoS 2 nanosheets having high mobility of charge carriers[35][36][37][38][39][40][41][42]44 . A qualitative comparison of our work with other reported work has been mentioned inTable 1[45][46][47][48][49] .…”

Revealing the role of the 1T phase on the adsorption of organic dyes on MoS2 nanosheets

“…12,13 The 1T-MoS 2 phase was found to be a superior catalyst due to the high carrier mobility, higher hydrophilicity and abundant active sites, not only at the edges of the nanosheets but also within the basal plane of the 1T phase. [14][15][16] Recent studies have shown that the 1T and 2H phases coexist in single layers of hybridized MoS 2 (ref. [17][18][19] with 1T-phase concentration up to 70%.…”

Active Site Engineering on Two-Dimensional-Layered Transition Metal Dichalcogenides for Electrochemical Energy Applications: A Mini-Review

“…The E 1 2g /A 1 g peaks of defect-rich MoS 2 and bulk MoS 2 are at ∼380.7/406.1 and∼383.0/408.5 cm −1 , respectively. Compared to bulk MoS 2 , the Raman peaks of defect-rich MoS 2 blue-shift, possibly owing to the vacancies in its structure [49]. Furthermore, the broader and weaker Raman peaks of the defect-rich MoS 2 than bulk MoS 2 imply its weak crystalline and abundant defects in its basal plane [50][51][52].…”
