摘要：
In this paper, a high specific surface area lamellar heterogeneous composite catalyst (MCN) was synthesized for the cycloaddition reaction of CO2 2 and epoxides. MCN is doped aluminum with high catalytic activity in Bi2S3 2 S 3 and g-C3N4 3 N 4 with photocatalytic activity, and it was prepared by a facile one-step calcination method. This catalyst achieved 88 % and 97 % conversion and selectivity for the cycloaddition reaction of epichlorohydrin and CO2 2 with no change in yield after five cycles. In addition, the two compositions of Bi2S3 2 S 3 and g-C3N4 3 N 4 in MCN resulted in enhanced light absorption of the catalyst, thus providing some photothermal performance. This paper provides an idea for the design of bifunctional catalysts with Lewis acid-base.
