Abstract

As an important greenhouse gas, the increase in emissions of carbon dioxide (CO₂) has become one of the main drivers of global climate change. This paper systematically discusses the source, adsorption treatment method and conversion technology of CO₂. First of all, the sources of CO₂ are divided into two categories: natural processes and human activities. Among them, CO₂ generated by human activities is the main cause of environmental problems such as global warming. Subsequently, the article introduces the adsorption method as an important means of CO₂ treatment, covering the adsorption principle, common adsorbent types, adsorption process and adsorption regeneration methods. Finally, this paper focuses on the conversion technology of CO₂, including thermal catalytic conversion, photocatalytic conversion and electrocatalytic conversion. Each method has unique advantages and challenges, and provides different ideas and solutions for the effective conversion and utilization of CO₂.
