By utilizing Metal-organic framework (MOF) materials as a base, constructing electrocatalysts with heterogeneous structures offers advantages for catalyzing water splitting. In this study, hollow nanocatalyst, Ir-MIL-88A@NiFe-LDHs, was prepared by growing layered double hydroxides (LDHs) shell on MIL-88A substrate. The catalyst shows excellent oxygen evolution reaction (OER) performance in 1.0 M KOH solution, requiring only 217 mV overpotential to achieve current density of 10 mA cm

Abstract Electrochemical nitrate reduction reaction (NO 3 − RR) has promising prospects for green synthesis of ammonia and environmental remediation. However, the performance catalysts at high current density usually suffers from energy barrier ) to nitrite 2 competitive hydrogen evolution. Herein, we proposed a two‐step relay mechanism through spontaneous redox followed electrochemical by introducing low‐valence Fe species into Ni P nanosheets significantly enhance NO RR industrial density. The existence bypasses step with produce O , regulates electronic structure reduce NH thirdly prohibits evolution consuming excess active recover species. triple regulations via during reactions guarantee Fe‐Ni P@NF yield 120.1 mg h −1 cm −2 Faraday efficiency more than 90% over wide potential window long‐term stability 130 ~1000 mA . This work provides new strategy realize design electrocatalysts densities.

Hydrogen is one of the most promising green energy alternatives due to its high gravimetric density, zero-carbon emissions, and other advantages. In this work, a CoFeBP micro-flower (MF) electrocatalyst fabricated as an advanced water-splitting by hydrothermal approach for hydrogen production with highly efficient evolution reaction (HER) oxygen (OER). The fabrication process MF systematically optimized thorough investigations on various synthesis post-annealing parameters. best electrode demonstrates HER/OER overpotentials 20 mV 219 at mA/cm2. MFs also exhibit low 2-electrode (2-E) cell voltage 1.60 V 50 mA/cm2, which comparable benchmark electrodes Pt/C RuO2. demonstrate excellent 2-E stability over 100 h operation under harsh industrial operational conditions 60 °C in 6 M KOH current density 1000 flower-like morphology can offer largely increased electrochemical active surface area (ECSA), systematic lead improved crystallinity MFs.
