Abstract

SnS2 nanoplates are used as sacrificial templates to facilitate the in situ growth of intermetallic compound Pt3Sn nanoparticles. The Pt3Sn/SnS2 heterostructures show promise for selective NO2 sensing due to the favored gas adsorption and gas-solid charge transfer on Pt3Sn, combined with the optimized film conductance and formation of ohmic-type Pt3Sn/SnS2 heterointerfaces.

摘要

二硫化锡纳米片用作牺牲模板，以促进金属间化合物Pt3Sn纳米颗粒的原位生长。由于Pt3Sn上有利的气体吸附和气固电荷转移，结合优化的薄膜电导率和欧姆型Pt3Sn/SnS2异质界面的形成，Pt3Sn/SnS2异质结构在选择性NO2传感方面显示出前景。
