Needle‐Leaf‐Like Cu₂Mo₆S₈ Films for Highly Efficient Visible‐Light Photocatalysis

Abstract

Ternary sulfide Cu2Mo6S8 films with needle‐leaf‐like structures are grown on copper plates via a facile two‐step route. The needle‐leaf‐like Cu2Mo6S8 structures are directly converted from pregrown Cu(OH)2 nanowires on copper plates via a hydrothermal process. Interestingly, under visible light the hierarchically structured Cu2Mo6S8 films exhibit significantly improved photocatalytic performance in the degradation of methylene blue dye when compared to Cu(OH)2 nanowires. This result is attributed to the larger surface area from the dendritic Cu2Mo6S8 structures and the inherently faster charge transport rate of Cu2Mo6S8 as compared to Cu(OH)2.

Refractory‐Metal‐Based Chalcogenides for Energy

“…[ 104 ] This type of ternary metal chalcogenides is a member of the important family called as Chevrel phase and provides promising property such as superconductivity. Up to now, Chevrel phases were employed as cathode material for rechargeable Mg batteries, [ 105 ] electrocatalysts in H 2 evolution reaction, [ 106 ] visible‐light photocatalyst, [ 107 ] etc.…”

Preparation of Ga0.25Zn4.67S5.08 Microsphere by Ultrasonic Spray Pyrolysis and Its Photocatalytic Disinfection Performance under Visible Light

“…Therefore, it is imperative to develop a new type of high-efficiency photocatalyst to make up for the shortcomings of traditional materials. Recent series of studies have shown that ternary sulfides such as Cu 3 SbS 3 [15], ZnIn 2 S 4 [16], Cu 2 Mo 6 S 8 [17], and CuS x Se 1-x [18] are highly attractive due to their low cost, excellent electrical properties, and nonlinear optical properties. Particularly, their physicochemical properties can be facile regulated by adjusting the composition of each element, making them stand out among many new photocatalysts [19].…”
