PdTe Nanowires as an Efficient Multifunctional Catalyst for CO and O Electroreduction. (2025)

Discovering a multifunctional electrocatalyst that can achieve the selective electrochemical reduction of a variety of small molecules (such as CO and O, etc.) is a highly promising process. However, most reported Pd-based nanomaterials can only convert one kind of small molecule. In this study, we have constructed PdTe intermetallic nanowires (PdTe NWs) with numerous low-coordinated atoms, which can serve as an efficient and multifunctional catalyst for CO reduction reaction (CORR) and oxygen reduction reaction (ORR). For CORR, PdTe NWs can achieve CO Faraday efficiency (FE) of 96.2% at the potential of -0.8 V versus RHE. For ORR, PdTe NWs have selectivity for HO of over 90%. Moreover, at 0.2 V versus RHE, the HO production rate of PdTe NWs can achieve 1624.2 mmol g  h, which is approxima
