Abstract

The issue of climate change caused by excessive carbon dioxide (CO₂) emissions has garnered widespread attention. This paper reviews the current major technologies for CO₂ treatment, including carbon capture and storage (CCS) and CO₂ utilization. CCS technology effectively reduces atmospheric CO₂ concentrations by injecting captured CO₂ underground for long-term storage, thereby mitigating climate change. Additionally, improvements in technology can enhance oil recovery rates. CO₂ utilization transforms CO₂ into high-value chemicals such as methane and carbon monoxide (CO) through thermal catalysis, photocatalysis, and electrocatalysis. Despite challenges such as low energy efficiency and high costs, these technologies show significant potential in reducing carbon emissions and promoting carbon recycling.
