“…Apart from potential health impacts of VOCs, they are also involved in photochemical reactions leading to the formation of oxidants, which have serious deleterious effects on human health, agricultural crops, trees, natural vegetation, buildings, materials, etc. (Lin et al 2013;Prabhat Kumar et al 2011;Zou et al 2006). Chlorobenzene is a colorless and flammable aromatic compound with molecular formula C 6 H 5 Cl.…”

“…There are various technologies, which have been currently used for the treatment or elimination of VOCs. Physicochemical and biological treatment methods are available for the removal of VOCs by recovery method or destruction method (Berenjian et al 2012;Das et al 2004;Font et al 2011;Huang et al 2016;Prabhat Kumar et al 2011;Reddy et al 2011). Biological treatment techniques are designed on the capability of microorganisms to degrade the organic pollutants under aerobic conditions through oxidative and reductive reactions to water vapor, carbon dioxide, inorganic products and organic biomass.…”

“…Drawback with absorption technique generates wastewater which needs further treatment, high initial investment, difficult in design, start-up time constraints, requires a precise maintenance of the system, and is not suitable method for lower concentrations of VOCs (Khan and Kr. Ghoshal 2000;Prabhat Kumar et al 2011). The traditional methods used for VOCs treatment such as adsorption on activated charcoal, biofiltration and normal treatment methods are challenged by many factors such as energy requirements, expenses for scaling up large-scale applications, inefficient to degrade most of these organic compounds, generation of toxic organic by-products, reusability problem, generation of waste and waste disposal problem (Eltouny 2009;Huang et al 2016).…”

Volatile organic compounds (VOCs) are one of the major pollutants present in the petrochemical industrial effluents. These VOCs have high vapor pressure, which makes it to be dispersed into the atmosphere easily. Chlorobenzene is one such VOC, which has an ability to cause adverse impacts on human health by damaging the central nervous systems. The available treatment methods are unable to effectively treat such VOCs in environment. Photocatalytic degradation is the effective and economical methods, which are being used for the treatment of such pollutants. ZnO is one of the widely accepted photocatalyst, but it has a limitation of wide band-gap energy utilization. This paper mainly investigates the preparation of metal-doped ZnO nanoparticles using solgel technique and its application for the degradation of chlorobenzene in an aqueous media under different light sources. Among the modified ZnO nanoparticles prepared (Ag/ZnO, Cd/ZnO and Pb/ZnO), Pb/ZnO was found to be very effective in the degradation of chlorobenzene and achieved up to 100% within a short duration (< 120 min). The Pb/ZnO was also used as a photocatalyst in a vertical continuous photoreactor for the photodegradation of chlorobenzene using LED light.

This paper briefly describes the meaning and impact of ESG, and what kind of effect and role it has had on the world and enterprises. After that, this thesis takes Li Auto Company as an instance to analyze the performance of this company in terms of environment, society and regulation. Use the data and measures of Li Auto in terms of environment, society and regulation to analyze the performance of Li Autos ESG. There is also an analysis based on the comparison of Li Autos 2021 and 2022 reports and the ESG performance of other renewable car companies in the same industry. In the research, it is found that the performance of Li Auto Company in terms of ESG is relatively upstream among its peers, based on Li Autos ESG report and ESG-risk rating. This paper will deepen people's understanding of the ESG development of Li Auto Company. Furthermore, the ESG research on Li Auto will serve as a recommendation and reference for the development of ESG for Li Auto and other car companies.
