Abstract

HighlightsMetal oxide and carbon hybrids (MOx/C) were micropatterned very rapidly and energy efficiently by direct laser writing.Metal-organic framework was the ideal precursor for fabricating homogeneous MOx/C hybrids due to regularly spaced metal ions and organic ligands.The fabricated sensor not only demonstrated broad-range gas sensing capability for ethanol gas (170-3,400 ppm) but also exhibited exceptional sensitivity, rapid response and recovery, selectivity, linearity, and thermal stability.
