摘要

In this work, an ultrathin 2D/2D g-C3N4/Ti3C2 heterojunction was synthesized by direct calcination of a mixture of urea and multilayer Ti3C2 for photocatalytic degradation of tetracycline. Among them, urea is the precursor for the generation of g-C3N4 and generates gas to peel the multilayer Ti3C2 into fewer layers while reacting, solving the problem of low yield for the preparation of fewer layers of Ti3C2. The experimental results of tetracycline degradation under visible light showed that pure g-C3N4 (UCN) exhibited weak photoactivity; however, its photocatalytic performance was enhanced when Ti3C2 was coupled with g-C3N4. The best sample (5TC) could degrade 90.1% of tetracycline within 30 min. After four cycles of stability test, the photocatalytic performance did not change significantly, indicating that the prepared 2D/2D g-C3N4/Ti3C2 heterojunction possesses strong photocatalytic performance along with good stability.
