Abstract
- Environmentally friendly and efficient transition metal phosphide (TMP) electrocatalysts for oxygen evolution reaction (OER) are developed to meet the growing demand for clean energy. Here we report a novel and environmentally friendly strategy for the preparation of MOF-derived bimetallic phosphide embedded in the carbonaceous matrix (FeNiP/C). With 3-dimensional hollow barrel shape and high specific surface, FeNiP/C-900 performs excellent OER catalytic performance, reaching a current density of 10 mA cm−2 at an overpotential of 229 mV with a low Tafel slope of 74.5 mV dec−1. Meantime, we explore the thermal conversion mechanism of P-containing MOF and the compositional changes during heat treatment.
