Development of new and green strategy for C(sp 3 )-N bond cleavage is very interesting. Herein, we report the work for photocatalytic cleavage of C(sp 3 )-N bond of trialkylamines, in concurrent with formation of dialkylamines and olefins. It was found that rationally designed 2-dimensional Bi 2 WO 6 @ 1-dimensional LaPO 4 heterostructure (2D-Bi 2 WO 6 @1D-LaPO 4 ) was very efficient for the reaction due to high light collection efficiency and unique catalytic properties of 2D-Bi 2 WO 6 @ 1D-LaPO 4  and the strategy can be used for different trialkylamines, including triethylamine, tri-n-propylamine, and ethyl-di-isopropylamine. The mechanistic investigation indicated that the catalyst with heterostructure was not only favorable for charge carrier separation but also render excited electrons with high reduction capacity. This work opens a way for C(sp 3 )-N bond cleavage of trialkylamines.
