[HTML][HTML] Electronic structure modulation with ultrafine Fe3O4 nanoparticles on 2D Ni-based metal-organic framework layers for enhanced oxygen evolution reaction
Abstract Two-dimensional (2D) metal organic frameworks (MOFs) are emerging as low-cost
oxygen evolution reaction (OER) electrocatalysts, however, suffering aggregation and poor
operation stability. Herein, ultrafine Fe 3 O 4 nanoparticles (diameter: 6±2 nm) are
homogeneously immobilized on 2D Ni based MOFs (Ni-BDC, thickness: 5±1 nm) to improve
the OER stability. Electronic structure modulation for enhanced catalytic activity is studied via
adjusting the amount of Fe 3 O 4 nanoparticles on Ni-BDC. The optimal Fe 3 O 4/Ni-BDC …
