摘要:
A method for manufacturing an NO2 gas sensor for detection at room temperature comprises: manufacturing a metal electrode on a surface of a flexible substrate; manufacturing an SWCNTs/SnO2 sensitive film; and bonding the SWCNTs/SnO2 sensitive film with a portion of the surface of the flexible substrate with the metal electrode, so as to form the NO2 gas sensor for detection at room temperature. The present disclosure solves the problems of the poor adhesion between the sensitive material and the flexible substrate, and a non-uniform distribution, and achieves the purposes of secure bonding between the sensitive material and the flexible substrate, and uniform distribution.

The present disclosure provides a method for manufacturing ordered nanowires array of NiO doped with Pt in situ, comprising: growing a Ni layer on a high-temperature resistant and insulated substrate; applying a photoresist on the Ni layer, pattering a pattern region of the ordered nanowires array by applying electron beam etching on the photoresist, growing Ni on the pattern region of the ordered nanowires array, peeling off the photoresist by acetone and etching the surface of the Ni layer by ion beam etching so as to etch off the Ni layer grown on the surface of the substrate and to leave the Ni on the pattern region of the ordered nanowires array to form the ordered Ni nanowires array; dipping the ordered Ni nanowires array into a solution of H2PtCl6 so as to displace Pt on the Ni nanowires array by a displacement reaction; and oxidizing the Ni nanowires array attached with Pt in an oxidation oven to obtain the ordered nanowires array of NiO doped with Pt. The present invention is simple and practical and the sensitivity and reliability of the doped sensor on the gas of CO and H2 are greatly improved.
