Abstract:
The electrocatalytic nitrate reduction reaction (eNO3RR) relies on multi-tasking functionality to overcome the difficulty of electron/mass transfer, but a catalyst of a single metal element could not achieve this. Spontaneous oxidative reconstruction endows a catalyst with multitasking capabilities, enhancing the performance of the eNO3RR. The spontaneously reconstructed S-FeOOH exhibits outstanding eNO3RR performance (FE = 93.7% and yield = 80.2% of NH3), providing new design principles for high-performance nitrate reduction catalysts.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
