Boosting Visible-Light Photocatalytic Hydrogen Evolution with an Efficient CuInS2/ZnIn2S4 2D/2D Heterojunction

“…Pure CuInS 2 exhibits strong visible-light absorption in a wide range. The absorption edge of pure CuInS 2 is at about 890 nm and the band gap value of CuInS 2 is calculated to be about 1.40 eV (see Figures S1 and S2), which is close to that in previous studies. , As can be seen from Figure , the absorption edges of all CuInS 2 /ZnIn 2 S 4 composite samples are extended to about 800 nm. With the increase content of CuInS 2 , the visible-light absorption of CuInS 2 /ZnIn 2 S 4 composites is gradually enhanced.…”

Sustainable Nanoplasmon‐Enhanced Photoredox Reactions: Synthesis, Characterization, and Applications

“…Plasmonic copper sulfide has also showcased its potential towards photo degradation of several organic dyes such as Rhodamine B, Congo red, methylene blue, methyl orange, etc. [ 181–183 ] Cu 7 S 4 /graphene oxide composites were used for photo catalytic degradation of Rhodamine B dye using real sunlight, the plausible mechanism for which is shown in Figure 18 . [ 181 ] The efficient electron‐transfer ability of graphene oxide in conjunction with the broadband solar absorption of Cu 7 S 4 nanoparticles contribute to the photodegradation activity under sunlight.…”

Highly Active Agro-Waste-Extracted Cellulose-Supported CuInS2 Nanocomposite for Visible-Light-Induced Photocatalysis

“…8−10 Further, CuInS 2 thin films had been widely used as absorber layers to utilize visible light in photovoltaic cell, but very few reports are available on CuInS 2 as a visible-light-responding photocatalyst for degradation of organic dyes. 11,12…”

“…8−10 Further, CuInS 2 thin films had been widely used as absorber layers to utilize visible light in photovoltaic cell, but very few reports are available on CuInS 2 as a visible-light-responding photocatalyst for degradation of organic dyes. 11,12 Photocatalytic activity of bare CuInS 2 is poor due to fast charge carrier recombination. To improve the photocatalytic performance, various efforts have been made in the past, such as nanostructure synthesis with morphology control, elemental doping, and facet engineering, 13 which aid in light harvesting and charge movement.…”

“…Enhancement in electrochemical performance is visible when CIS is applied in lithium-ion batteries . CIS, ZnO/CIS core–shell nanoarrays, and graphene/graphene oxide/CIS nanofilms have been used for the electrochemical water splitting. − Further, CuInS 2 thin films had been widely used as absorber layers to utilize visible light in photovoltaic cell, but very few reports are available on CuInS 2 as a visible-light-responding photocatalyst for degradation of organic dyes. , …”
