Selectivity control of Ni-doped copper oxide at high operating temperatures

Abstract

Gas sensors are of major importance in today's industrial, chemical, agricultural, energy and household fields, and their development for general consumer use is an area of growing interest. This study explores the development and hydrogen sensing performance of CuO nanostructures synthesized via a cost-effective chemical solution method. The nanostructures, composed of copper oxide granules uniformly coated with nickel nanoparticles, were deposited on a glass substrate and thermally treated using rapid thermal annealing (RTA) to minimize defects.
