Abstract
Abstract
The prevalence of indoor air pollution, primarily stemming from human activities, has led to increasing concerns regarding elevated CO2 concentrations in indoor environments. Prolonged exposure to such environments has been linked to reduced productivity, headaches, nausea, and more severe health risks, such as Sick Building Syndrome. Consequently, the development of efficient methods to reduce CO2 concentrations in indoor air is of utmost importance. This review offers a comprehensive analysis of cutting-edge indoor CO2 capture technologies, delving into the adsorption performance of solvents produced via various techniques. Our findings highlight the emergence of innovative materials that significantly enhance the indoor adsorption process; nevertheless, further investigation into reaction kinetics and stability remains imperative for continued progress. Among the methods assessed, Thermal Swing Adsorption and Wet Impregnation demonstrate superior suitability for indoor CO2 capture applications. Importantly, this review also emphasizes the potential of novel ventilation strategies, incorporating both internal ventilation and CO2 capture devices, to not only reduce indoor CO2 concentrations but also promote energy efficiency in buildings.
