Environmental aspects of using artificial photosynthesis technology for environmental decarbonization

Abstract

The increasing levels of carbon dioxide (CO₂) in the atmosphere have been recognized as a major contributor to global climate change. As a result, there is a pressing need to develop sustainable and eco-friendly methods for mitigating CO₂ emissions. CO₂ recycling has emerged as a promising solution, aiming to convert CO₂ into valuable products while reducing its impact on the environment. This work uses the CO₂ recycling approach, which involves the conversion of CO₂ emissions into useful organic compounds. An experiment with artificial photosynthesis is carried out with the help of a special installation, where CO₂ undergoes photochemical reactions that contribute to the formation of organic compounds. Photocatalytic conversion of CO₂ is environmentally friendly as it uses light energy and renewable raw materials to produce valuable chemicals without producing harmful by-products or waste. It has been established that TiO₂ in the form of anatase and rutile is the most common CO₂ photocatalyst. As a result of the experiment, the main output products were methanol, acetate aldehyde and acetone. The use of ultraviolet radiation and an electric field significantly affected the synthesis of organic substances and their quantity. It can be used in various industries such as fuel, chemical and pharmaceutical industries. In particular, methanol, acetate aldehyde and acetone are promising substances for the use and production of biofuels.
