Although they are not as favorable other influential gas sensors, metal-oxide semiconductor-based chemiresistors ensure minimal surface reactivity, restricting their selectivity, response, and reaction kinetics, particularly when functioning at room temperature (RT). A hybrid design, which includes metal-oxide/carbon nanostructures passivation with specific filtration layers, can address the concerns of reactivity. We present a novel hierarchical nanostructured zinc oxide (ZnO), decorated...
