摘要

•pn Junction type nanocomposite sensors of SWCNT/ZnO for hydrogen sensing.•The composite responded to ppm levels of H2 andexhibited the highest response at RT.•The mechanism of enhanced H2 response in the composite sensor at RT was elaborated.•Our results pave the way to build a portable and low-powered device for H2 breath test.
