Problems solved by technology

However, the photocatalytic oxidation removal of VOCs still faces challenges such as low light energy utilization rate and poor catalytic effect. At the same time, although thermal catalysis can input the energy required for VOCs degradation through external heating, the process consumes high energy and costs a lot. It is not conducive to the green development and application of this technology

Description

technical field [0001] The invention relates to the technical field of nanometer and photothermal catalysis, in particular to an in-situ photothermal preparation of spinel-structured Cu 1.5 mn 1.5 o 4 Methods of catalysts and their applications. Background technique [0002] Volatile organic compounds (Volatile organic compounds, VOCs) emissions from human production activities such as global industrial production and motor vehicle driving are increasing year by year. As the main air pollutants, VOCs are not only neurotoxic, carcinogenic and teratogenic, but also the most important precursors of fine particulate matter and photochemical smog, causing serious harm to the natural environment and human health. Therefore, the research on the catalytic oxidation technology of VOCs has attracted more and more attention from scientific researchers. Photocatalytic technology is considered as a promising environmental purification technology due to its mild reaction conditions. ...
