Title: Highly Stable Transparent Conductive Electrodes Based on Silver–Platinum Alloy-walled Hollow Nanowires for Optoelectronic Devices

Abstract

In industrial manufacturing, alloying can contribute to the passivation of active metals and markedly improve their corrosion resistance. This inspires us to solve the current critical problem of Ag nanowires (Ag NWs) that have poor stability against chemical and electrochemical corrosion. These problems have seriously limited the applications of Ag NWs in optoelectronic devices where they are used for transparent conductive electrodes. Here, a kind of transparent conductive electrode based on Ag@Pt alloy-walled hollow nanowires (Ag@Pt AHNWs) is successfully fabricated by introducing 12 mol% Pt into long Ag NWs to form Ag@Pt alloy. The as-synthesized electrodes exhibit better optical transmittance (82% at the wavelengthof 550 nm) under high electrical conductivity (28.73 O/sq), high thermal stability up to 400 oC for 11 h, remarkable mechanical flexibility (remaining stable after 5000 cycles bending), as well as high resistance against chemical and electrochemical corrosion. The Ag@Pt AHNWs electrodes are further applied in primary bifunctional polyaniline electrochemical device, and the device shows promising flexibility, noticeable multicolor performances and the high specific capacitance due to the remarkable mechanical flexibility and electrochemical stability of Ag@Pt AHNWs. This work will provide an optional approach for the preparation of other metal nanomaterials electrode with high stability.
