Abstract
Various noble metals such as Au, Ag, Pd, Pt, Ru, and Rh are used for decorating resistive gas sensors because of their high catalytic activity and electronic effects, which boost the overall sensing characteristics of resistive sensors. However, bimetallic decorations such as AuPt, AuPd, PtPd, and AuAg are often preferred to boost the sensing capabilities because bimetallic combinations exert synergistic effects that enhance the catalytic features compared with that of their single-metal-decorated counterparts. In this review, we discuss the roles of different bimetallic couples in the sensing capacity of resistive sensors with specific emphasis on the underlying sensing mechanism. We believe that this review will be highly beneficial for researchers working in the field of gas sensors.
