MOF Thin Film‐Coated Metal Oxide Nanowire Array: Significantly Improved Chemiresistor Sensor Performance

Abstract

A strategy for combining metal oxides and metal-organic frameworks is proposed to design new materials for sensing volatile organic compounds, for the first time. The prepared ZnO@ZIF-CoZn core-sheath nanowire arrays show greatly enhanced performance not only on its selectivity but also on its response, recovery behavior, and working temperature.
