光催化还原CO_(2)制甲烷催化剂专利技术研究进展

Review on Patent Technology of Catalyst for Photocatalytic Reduction of CO_(2) to Methane

CO_(2)甲烷化是实现碳中和的重要途径。光催化还原CO_(2)制甲烷的关键在于寻找高效的催化剂,尽可能提高CO_(2)的转化率和甲烷的选择性。文章主要根据国内外光催化CO_(2)甲烷化催化剂的专利申请,从国内外申请趋势、主要申请人分布、核心专利、各催化剂技术分支的发展状况等方面明晰了光催化CO_(2)甲烷化的研究进展。同时,指出当前光催化CO_(2)甲烷化催化剂存在的不足、研究热点和应对策略,并对未来的发展趋势进行展望。

CO_(2)methanation is an important way to achieve carbon neutrality.The key to photocatalytic reduction of CO_(2)to methane is to f ind an eff icient catalyst to improve the conversion rate of CO_(2)and the selectivity of methane as much as possible.Based on the patent applications of photocatalytic CO_(2)methanation catalysts at home and abroad,this paper clarif ies the research progress of photocatalytic CO_(2)methanation in terms of domestic and foreign application trends,distribution of main applicants,core patents,and development status of each catalyst technology branch.At the same time,the shortcomings,research hotspots and coping strategies of the current photocatalytic CO_(2)methanation catalysts are pointed out,and the future development trend is prospected.
