“…It has been reported that combining inorganic and organic materials in the form of composite or nanocomposite can enhance performance and generate unique characteristics for gas sensing devices [ 23 ]. In light of this, metal oxides are favorable candidates due to their intrinsic electronic properties, in addition to also being used in the field of anti-bacterial, structural, and electrical applications [ [29] , [30] , [31] , [32] ]. ZnO is an inorganic metal oxide that has specific characteristics, such as: wide bandgap, excellent mechanical strength, good chemical stability, nontoxicity, high conductivity, large exciton binding energy, and in powdered form has a high surface area which favors increased throughput that demonstrates good applicability in gas sensing devices [ [33] , [34] , [35] , [36] ].…”
