Life cycle assessment can be used to evaluate the environmental issues involved in the entire product production process (including raw material acquisition, production, transportation, use/maintenance and final disposal). It is an important support tool for screening and developing an efficient, low-cost and environmentally friendly product. In this study, based on the life cycle method, an environmental impact assessment of the resource consumption and pollutant emission data was carried out for the mesoporous K-Ag/Co3O4 catalyst life cycle. The results show that the proportion of resource consumption to produce 1 kg of mesoporous K-Ag/Co3O4 is 0.132. Environmental impact types mainly contain fossil depletion, climate change, human health and particulate matter formation; The substances produced by mesoporous K-Ag/Co3O4 catalyst life cycle have the greatest impact on human health, including carcinogens, resp. inorganics and human toxicity. These substances are mainly gas pollutants, CO2 emission is the largest, followed by SO2 and CH4. Whether it is health impact, environmental impact or resource depletion, electricity consumption is the main factor. Thus, it is necessary to improve the production process and use low-power equipment to reduce the environmental impact of the entire life cycle. The use of mesoporous K-Ag/Co3O4 catalyst has purified a large amount of formaldehyde and has a good environmental effect.
