Dual regulation of hierarchical porosity and heterogeneous interfaces in Cu-BTC/Bi2MoO6 for thermally-driven and UV-light activated selective acetone sensing

A novel defective-Cu-BTC@Bi 2 MoO 6 (d-CuM@BMO) heterostructure was successfully fabricated through an etching-and-growth strategy, showing excellent selective and sensitive acetone sensing performances under the photoactivation of UV light.
