Novel gamma-irradiated chitosan-doped reduced graphene-CuInS₂ composites as counter electrodes for dye-sensitized solar cells

Abstract

To address the issues associated with traditional counter electrodes, a novel gamma-irradiated chitosan-doped reduced graphene-CuInS2 composite (Chi@RGO-CIS) was used as the counter electrode (CE).

An electrochemical sensor for flubendiamide insecticide analysis based on chitosan/reduced graphene oxide

“…[39][40][41] The combination of graphene and chitosan can provide significant benefits in terms of high adhesion, good stability, excellent absorption capacity, and significant electrochemical detection performance. 42,43 In this context, Islam et al synthesized CHI-graphene oxide films by dissolving CHI in 1% acetic acid and mixing an aqueous solution of CHI with GO suspension. 44 CHI and GO nanocomposites were formed from the addition of both components in aqueous media.…”

Synthesis and photothermal performance of non-stoichiometric molybdenum oxide (MoO3−x) prepared by gamma radiation

“…16 The same approach was applied to obtain metal oxide nanostructures as superparamagnetic cobalt ferrite 17 and Cu/Cu 2 O. 18 Other interesting reduction processes mediated by γ-radiation were the reduction of oxidized graphene, 19,20 p-doping of WS 2 , 21 synthesis of Prussian blue supported on polyvinylpyrrolidone, 14 silver nanoclusters, 22 and chitosan-doped reduced graphene-CuInS 2 as electrodes for dye-sensitized solar cells, 23 and for the modification of biomaterials. 24 The key point for the successful use of γ-rays as a reducing agent in a synthesis process is choosing the appropriate solvents, and the interfaces with the solid.…”

One-pot synthesis of iron oxide - Gamma irradiated chitosan modified SBA-15 mesoporous silica for effective methylene blue dye removal

“…The majority of structure-directing substances are pricy synthetic compounds with significant environmental effect. As a result, several studies have been done to develop substitute materials, with chitosan [ [17] , [18] , [19] , [20] , [21] ] being one among them. Chitosan is a naturally occurring biopolymer that is found in the exoskeletons of animals including shrimp, crabs, insects, and fungus [ 22 ].…”
