Hydrogen Sensing with Villous Zinc Oxalate
Journal Title: Nanomedicine & Nanotechnology Open Access - Year 2018, Vol 3, Issue 1
Abstract
Villous zinc oxalate (ZnC2O4) was synthesized using the sol–gel and laser method demonstrated in a previous paper, and the hydrogen-sensing properties of villous ZnC2O4 were investigated. The mixing ratio of reduced graphene oxide (RGO) to ZnO to form ZnC2O4 is predictive of its hydrogen-sensing capabilities. The microstructure evolution of villous structures was characterized by X-ray diffraction and field emission scanning electron microscopy techniques. Gas-sensing experiments tested response, recovery, and selectivity. The villous structure of ZnC2O4 can sense hydrogen at room temperature and an optimum operable temperature of 150°C at a specific C/Zn ratio. The strong hydrogen response is attributed to the villous structure and high C/Zn ratio of the 1:1 RGO to ZnO mixing ratio.
