Design of Selective Gas Sensors Using Additive-Loaded In(2)O(3) Hollow Spheres Prepared by Combinatorial Hydrothermal Reactions

A combinatorial hydrothermal reaction has been used to prepare pure and additive (Sb, Cu, Nb, Pd, and Ni)-loaded In(2)O(3) hollow spheres for gas sensor applications. The operation of Pd- and Cu-loaded In(2)O(3) sensors at 371 °C leads to selective H(2)S detection. Selective detection of CO and NH(3...

Sumario:A combinatorial hydrothermal reaction has been used to prepare pure and additive (Sb, Cu, Nb, Pd, and Ni)-loaded In(2)O(3) hollow spheres for gas sensor applications. The operation of Pd- and Cu-loaded In(2)O(3) sensors at 371 °C leads to selective H(2)S detection. Selective detection of CO and NH(3) was achieved by the Ni-In(2)O(3) sensor at sensing temperatures of 371 and 440 °C, respectively. The gas responses of six different sensors to NH(3), H(2)S, H(2), CO and CH(4) produced unique gas sensing patterns that can be used for the artificial recognition of these gases.
