Two‐dimensional (2D) tungsten diselenide (WSe 2 )‐based porous three‐dimensional (3D) architecture is fabricated utilizing highly porous 3D alumina structures. The architecture is produced by combining a sol–gel process for fabricating porous 3D alumina and chemical vapor deposition (CVD) for the formation of WSe 2 . The gas‐sensing performance of the porous 3D structure overcomes the limitations displayed by the gas response of a 2D WSe 2 ‐based gas sensor. This 2D nanomaterials‐based porous 3D architecture is a promising approach for improving the gas response of sensing devices.
