This study focused around the adsorption of numerous gases which include N, CO2 , and CH4 over the ready material and reported selective adsorption of CO2 , compared with N and CH4 , and relatively high capture capacity for the synthesized adsorbent for CO2 uptake. The nature of adsorption was reported to be physisorption or weak chemisorption. Removal of ammonia gas by PANITiO2 as photocatalyst was reported by [82] below visible light and below UV radiation. They reported that the removal efficiency decreased because the reaction time elevated. In addition, CO2 reduction to alcohol by polyaniline film was reported by [83]; their proposed reaction mechanisms are presented in Figure four. Removal of a variety of volatile organic compounds (VOCs) by several forms of polyaniline was reported by [84]. They reported that the primary mechanisms that are at play within the removal of VOCs will be the interactions between PANI backbone and the unsaturated hydrocarbons, which resulted in greater removal of unsaturated (C=C) bonds present within the target analytes. As for the saturated hydrocarbon-based VOCs, the primary interactions are weak hydrogen bonding and weak Van der walls forces amongst PANI along with the saturated molecules owing for the lack of readily available electrons. General, the kind of PANI (EB or ES), surface region, morphology, as well as the sort of doping agent (dopant) can significantly affect the VOC ANI interactions and also the removal functionality. Adsorption of a flue gas NO2 by polyaniline lay nanocomposite was reported by [85]. They reportedly prepared polyaniline composites with three distinct clays–namely, PF-05105679 medchemexpress attapulgite (ATP), vermiculite (VEM), and diatomite (DIM), and (-)-Irofulven custom synthesis concluded that the PANI TP composite revealed the higher adsorption capacity for NO2 removal. Surface morphologies of some PANI-based adsorbents are presented in Figure five.Polymers 2021, 13,PANI interactions and also the removal functionality. Adsorption of a flue gas NO2 by polyaniline lay nanocomposite was reported by [85]. They reportedly prepared polyaniline composites with three unique clays–namely, attapulgite (ATP), vermiculite (VEM), and diatomite (DIM), and concluded that the PANI TP composite revealed the high 10 adsorption capacity for NO2 removal.
