Dual-Functional Electrocatalyst Derived from Iron-Porphyrin-Encapsulated Metal–Organic Frameworks
Source abstract
Abstract
Active, stable electrocatalysts based on non-precious metals for the oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) are critical for the development of cost-effective, efficient renewable energy technologies. Here, Fe/Fe 3 C-embedded nitrogen-doped carbon was fabricated via pyrolysis of iron-porphyrin-encapsulated mesoporous metal–organic frameworks [PCN-333 (Fe), where “PCN” stands for “porous coordination network”] at 700 °C. The various characterization techniques confirmed that Fe- and Fe 3 C-containing Fe–N–C material (FeP-P333-700) was successfully prepared by pyrolysis of porphyrin-encapsulated PCN-333 (Fe). FeP-P333-700 exhibited superior electrocatalytic performance for the ORR and HER owing to the synergistic effect of Fe/Fe 3 C and Fe–N–C active sites.
