Effect of rapid thermal annealing in furnace of nanocrystallite Cu1-xZnxOy films on hydrogen gas response

Abstract

Hydrogen (H2) is expected to be “the fuel of the future” and can be used in the future power devices, H2 engine cars, solid oxide fuel cells [1]. But hydrogen gas forms explosive mixtures with air if it is 4–74% concentrated and with chlorine if it is 5–95% concentrated. Thus, it is necessary to detect hydrogen leakage in the environment. In this work, nanocrystallite Cu1-xZnxOy films were synthesized from chemical solution (SCS) of copper sulfate, zinc sulfate, sodium thiosulfate and rapid thermal annealed (RTA) in furnace at different temperatures and durations. Morphological and structural studies were performed in our previous work.
