Chemiresistive gas sensors have been widely applied to monitor analytes of environmental, food and health importance. Among the plethora materials that can be used for designing chemiresistive sensors, ZnO is one most explored sensing, as this material has a low-cost, non-toxic easily obtained through standard chemical synthesis. Adding this, form heterostructures capable improve sensor performance regarding sensitivity, selectivity stability. Moreover, also contribute lower operating temperature since synergistic effects amplify signal. In review, we survey recent advances on different types ZnO-based focusing how morphology structure these influence response. Challenges future perspectives are discussed.
