Abstract

Summary: Energy crisis has become an urgent problem in the world. Hydrogen is a continuous and clean energy, but traditional electrocatalytic materials for water splitting have the shortcomings including high cost and low hydrogen production efficiency. Herein, we prepare a biomass carbon‐based electrocatalyst doped with iron and nitrogen. The overpotential of so‐obtained CA (abbreviation of "carbon from amaranth") @Fe(1:3)‐800 is only 265 mV at 10 mA cm −2 for oxygen evolution reaction (OER), as well as the Tafel slope is 76.7 mV dec −1, which are much superior to the results of CA‐800 (the overpotential is 514 mV and the Tafel slope is 160.2 mV dec −1 ). It shows the positive influences of dual‐doping with iron and nitrogen in biomass carbon. Our work opens up a low‐cost and green avenue for fabricating high‐performance electrocatalyst in hydrogen production field. Abstract : A biomass carbon derived from amaranth and K3[Fe(CN)6] to realize dual‐doping with iron and nitrogen, showing a high‐performance electrocatalysis property with the water splitting voltage of 1.53 V.
