Nanosensors Engineering: Ii. Superficial Functionalization Of Sno₂ Nanowire For Sensing Performance Improvement

Paper presents results of study aimed the tin dioxide nanowire gas sensing performance improvement via in situ functionalization with NiO. Developed nanostructures have demonstrated improved by order gas sensitivity toward H2 and CO and drastic increase of selectivity to H2 against CO. Obtained results are discussed from the point of view of NiO/Sno₂ heterojunction formation and its influence on electrical transport through nanowire and nanowire interaction with target gases.
