Metastable materials are considered promising electrocatalysts for clean energy conversions by virtue of their structural flexibility and tunable electronic properties. However, the exploration synthesis metastable via traditional equilibrium methods face challenges because requirements high precise control. In this regard, rapid method (RSM), with efficiency ultra-fast heating/cooling rates, enables production under non-equilibrium conditions. relationship between RSM properties remains largely unexplored. review, we systematically examine unique benefits various techniques mechanisms governing formation materials. Based on these insights, establish a framework, linking electrocatalytic performance Finally, outline future directions emerging field highlight importance high-throughput approaches autonomous screening optimal electrocatalysts. This review aims to provide an in-depth understanding electrocatalysts, opening up new avenues both fundamental research practical applications in electrocatalysis.

The electrocatalytic reduction reaction of nitrate (NO3RR) is anticipated to convert nitrogen-containing pollutants into valuable ammonia products. Copper-based catalysts have received great attention because their good performance in the NO3RR due strong binding energy with *NO3 intermediates. However, poor H2O dissociation ability Cu unable provide H• time for hydrogenation NOx, thus hindering electroreduction NO3-. Herein, we designed a shell-core nanocube electrocatalyst Cu2O@Ni(OH)2-x (x represents molar ratio Ni/Cu) using liquid phase combined etching and precipitation method NO3RR. Due synergistic effect between activation excellent Ni(OH)2, Cu2O@Ni(OH)2-3.3% shows an impressive yield rate (557.9 μmol h-1 cm-2) Faradaic efficiency (97.4%) at -0.35 V vs. RHE. Operando Raman Auger electron spectroscopy observe Cu2O during process. Density functional theory calculations paramagnetic resonance analysis reveals that Ni(OH)2 can lower barrier dissociation, thereby promoting generation accelerating *NO This research provides efficient Cu-based catalyst reducing NO3- may motivate development effective electrocatalysts further experimentation.
