Atomic-Layered Tungsten Diselenide-Based Porous 3D Architecturing for Highly Sensitive Chemical Sensors

초록

Two-dimensional (2D) tungsten diselenide (WSe2)-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 WSe2. The gas-sensing performance of the porous 3D structure overcomes the limitations displayed by the gas response of a 2D WSe2-based gas sensor. This 2D nanomaterials-based porous 3D architecture is a promising approach for improving the gas response of sensing devices.
