Polymers and transition-metal oxides have gained great interest as a photocatalyst in environmental remediation. They could be modified with each other in order to improve their activity. Here, a sunlight-responsive hierarchically structured ternary composite of nickel oxide, polyaniline, and reduced graphene oxide (NiO@PANI/RGO) has been synthesized and employed as a catalyst for dye [methylene blue (MB)] degradation. PANI/GO synthesized by interfacial polymerization acts as a matrix for the growth of NiO using a microemulsion solvothermal method, ensuing an in situ reduction of graphene oxide during the formation of a hierarchical NiO@PANI/RGO composite. Morphological studies of the as-synthesized NiO@PANI/RGO composite reveal fine NiO (10 nm) nanoparticles intercalated between the uniformly grown PANI spines (50–60 nm) over the RGO surface. The optical band gap of ∼1.9 eV calculated from the UV–vis spectrum illustrates the extended light absorption range for the NiO@PANI/RGO photocatalyst. The efficiency of 98% MB degradation within 11 min with the degradation rate constant 0.086 min –1 for NiO@PANI/RGO has surpassed any other report on metal oxide/graphene-based ternary composites. Overall, this work could pave the way for the fabrication of futuristic hierarchical structured ternary nanocomposites as an efficient photocatalyst and facilitate their application in the environmental protection issues.

A dodecylbenzene sulfonic acid (DBSA) doped-polyaniline (PANI) coated conductive viscose fiber (VCF) was prepared by chemical oxidation polymerization in an ethanol/water solution. Fourier transform infrared spectra (FTIR) and XPS proved that an interaction between PANI and VCF formed in the PANI/VCF composites. The mild treatment did not result in the oxidation and degradation of VCF detected by thermal gravimetric analysis (TGA) and mechanical testing. Moreover, the influence of the reaction conditions including reaction time, aniline monomer (ANI) concentration, ammonium persulfate (APS) concentration and DBSA concentration on the morphology and the conductivity of the PANI/VCF composites were investigated in detail. The orthogonal experiments were designed to determine the optimal reaction conditions as follows: ethanol/water ratio (30/70), reaction time (18 h), ANI concentration (0.1 mol L À1 ), APS concentration (0.125 mol L À1 ) and DBSA concentration (0.1 mol L À1 ).When the PANI/VCF composite was washed 40 times in water, the conductivity still remained at 2.5 Â 10 À2 S cm À1 , and this value was stable for more washing.

“…Moreover, incorporating magnetic nanoparticles into the binary composites of PANI/TiO 2 ensures that the photocatalyst can easily handle magnetic separation [84] and provides an effective approach for achieving a more efficient charge separation, resulting in increased photocatalytic activity [85,86]. Taking all these points into consideration, Xiong [35]. Moreover, it has been indicated that interactions between individual components in these ternary composites result in an enhancement of their electrical conductivities and photocatalytic activities, which is an especially important purpose of PANI coating.…”

Photocatalysts provide a sustainable method of treating organic pollutants in wastewater and converting greenhouse gases. Many studies have been published on this topic in recent years, which signifies the great interest and attention that this topic inspires in the community, as well as in scientists. Composite photocatalysts based on conducting polymers and metal oxides have emerged as novel and promising photoactive materials. It has been demonstrated that conducting polymers can substantially improve the photocatalytic efficiency of metal oxides owing to their superior photocatalytic activities, high conductivities, and unique electrochemical and optical properties. Consequently, conducting polymer/metal oxide composites exhibit a high photoresponse and possess a higher surface area allowing for visible light absorption, low recombination of charge carriers, and high photocatalytic performance. Herein, we provide an overview of recent advances in the development of conducting polymer/metal oxide composite photocatalysts for organic pollutant degradation and CO2 conversion through photocatalytic processes.
