“…According to the gas-sensing mechanism (Fig. 8), when the sensors based on ZnSnO 3 microspheres were exposed to air ambient, oxygen molecules adsorbed on the surface of ZnSnO 3 microspheres would capture electrons from the conduction band to form O 2 -, O -or O 2- [24], which increases the barrier height for electrons to transport and thus ZnSnO 3 microspheres will show a higher resistance [25]. The reaction processes can be explained in Eqs.…”

“…Hollow spheres can be obtained by different methods, including hard [19][20][21][22][23][24] and soft [25][26][27][28] template-assisted synthesis, oriented attachment, Kirkendall effect, and Ostwald ripening [29][30][31][32]. Some successful techniques for producing ZnO solid spheres include assembly of nanoparticles [33,34], nanorods [35], nanosheets [36] or nanoplates [36,37] via physical [38][39][40] and solution-based approaches [41][42][43][44] in the presence of noxious [45,46] or less toxic even "green" [47,48] additives.…”
