Ordered porous RGO/SnO₂ thin films for ultrasensitive humidity detection

Abstract

In this work, ordered porous thin films of reduced graphene oxide and tin oxide (rGO/SnO2) were synthesized by a polystyrene sphere monolayer colloidal crystal template method, and their gas-sensing properties...

Fast response flexible humidity sensors based on Ti3C2Tx MXene-heterostructures for multifunctional applications

“…As a representative semiconductor metal oxide, tin dioxide (SnO 2 ) has been recognized as an excellent sensitive material for humidity and gas detection due to its high sensitivity and electrochemical stability. 34–36 Furthermore, zero-dimensional nanoparticles with a large absorption coefficient and tunable bandgap are ideal nanomaterials for constructing heterostructures to enhance the sensing performance. 37…”

Fabry–Pérot Cavity Based on Metal–Organic Framework/Graphene Oxide Heterostructure Membranes for Humidity Sensing

“…The monitoring and controlling of humidity are greatly important because it is the basis for many applications, including the automated industry, agricultural production, precision instrument manufacturing, healthcare, and food industries. , Recently, humidity sensors have attracted extensive attention in the fields of breath detection and noncontact switches . Humidity sensors can realize noncontact detection of changes in the surrounding humidity environment, thereby avoiding the spread of bacteria in dangerous environments .…”
