Abstract
Abstract Electrochemical nitrate conversion to ammonia driven by sustainable green electricity is regarded as a promising supplement to the traditional Haber–Bosch process. However, it is still restricted by the low NH 3 yield rate and Faradaic efficiency. Here, we propose a continuous intermediates spillover strategy by constructing dual single‐atom alloy to boost ammonia yield rate and Faradaic efficiency. The intermediates continuously spill over back and forth on the atomically dispersed Mo and Fe sites in Pd lattice, which adaptively experiences low energy barrier for each elementary step in nitrate conversion. As a result, the synthesized dual single‐atom alloy metallene delivered an NH 3 yield rate of…
