“…Recently, PANI and magnetic iron oxide composite photocatalysts have been considered as good candidates for the adsorption and photodegradation of organic dyes in the treatment of wastewater due to their high charge transport properties and superparamagnetism at room temperature [ 108 , 109 ]. For instance, Alves et al reported a PANI/magnetic iron oxide composite for MB removal [ 26 ].…”

“…Importantly, due to the super-paramagnetic behavior, the PANI/magnetic iron oxide composite can be easily collected by applying a magnetic field and, therefore, can be reused in numerous cycles. Using a similar approach, Kharazi et al introduced the novel binary composite of copper spinel ferrite (CuFe 2 O 4 ) and PANI as an adsorbent and photocatalyst for the treatment of MO in wastewater [ 108 ]. With the presence of pre-synthesized CuFe 2 O 4 nanoparticles, the nanocomposite has a mesoporous structure with a BET surface area of 20.3668 m 2 /g, which showed excellent adsorption of the dye (capacity of 345.9 mg/g) and excellent magnetic properties.…”

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.

“…The PANI coupled with ferrite nanoparticles forms p-n heterojunctions, due to the perfect matching between valence and conduction bands that can enhance the electrical and gas sensing characteristics (Megha et al, 2017;Wang et al, 2020). The interface between PANI/ferrite nanoparticles leads to get desired applications, thus the addition of ferrite to the PANI led to an increase in thermal stability (Kharazi et al, 2019). Many researchers have been working in this area, though an in-depth study about the effect of the composition of ferrites on the electrical and gas sensing properties of PANI/ferrites nanocomposites is still deficient (Kaur et al, 2020).…”

Purpose This paper aims to study the various developments taking place in the field of gas sensors made from polyaniline (PANI) nanocomposites, which leads to the development of high-performance electrical and gas sensing materials operating at room temperature. Design/methodology/approach PANI/ferrite nanocomposites exhibit good electrical properties with lower dielectric losses. There are numerous reports on PANI and ferrite nanomaterial-based gas sensors which have good sensing response, feasible to operate at room temperature, requires less power and cost-effective. Findings This paper provides an overview of electrical and gas sensing properties of PANI/ferrite nanocomposites having improved selectivity, long-term stability and other sensing performance of sensors at room temperature. Originality/value The main purpose of this review paper is to focus on PANI/ferrite nanocomposite-based gas sensors operating at room temperature.
