Highly efficient photocatalytic synthesis of disulfides by a self-assembled CsPbBr3/Ti3C2Tx MXene heterojunction

Herein, CsPbBr 3 /Ti 3 C 2 T x MXene nanocomposites have been shown to catalyze the transformation of thiols into symmetrical and asymmetrical disulfides with high efficiency (29 700 μmol g −1 h −1 ), achieving moderate to excellent yields.
