Gas sensing properties of NiO/mesoporous SnO2

NiO/mesoporous SnO
2
was deposited by incipient wetness impregnation of the SnO
2
powder prepared by hydrothermal synthesis route templated by Brij® 35. The sensing properties were acquired and the dependence on the operating temperature of the sensitive material was pointed out. Sensitive selectivity towards H
2
S detection was highlighted at 350 °C.
