Abstract:
The efficient and durable catalysts toward electrochemical water-splitting plays significant role in clean and renewable energy storage applications. Herein, we design the Prussian blue analogues precursor by self-assembled strategy and converted it to (Fe-Co)Se2 composite by post-selenization method. Benefiting of unique porous morphology, high electrochemically active surface area and fast electron transfer ability, the excellent oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance of (Fe-Co)Se2 catalyst were obtained. It was revealed that only require overpotentials of 251 mV to arrive a current density of 10 mA cm-2 in OER system, and 90 mV was accomplished at a current density of 10 mA cm-2 toward the HER activity, along with low Tafel slope of 47.6 and 58.7 mV dec-1 was achieved for OER and HER, respectively. The (Fe-Co)Se2 catalysts with high electrochemical activity at the same time long-time durability may encourage more practical catalytic applications for renewable energy technologies.
