title: Nanosized LiNi1-xFexPO4 embedded in a mesoporous carbon matrix for high-performance electrochemical water splitting.
abstract: Splitting water to produce oxygen is the key technique in the development of various energy conversion processes including metal-air batteries, fuel cells and water splitting. Herein, for the first time, we report a mesoporous LiNi1-xFexPO4@C (0 ≤ x ≤ 1) nano-structure as a highly effective catalyst for electrochemical oxygen evolution reaction (OER) through a spray dry method. In particular, the LiNi1-xFexPO4@C (3 : 1) shows superior activity to those state-of-the-art noble metal catalysts (e.g., RuO2 and IrO2), which only needs an overpotential of 311 mV to afford a current density of 10 mA cm(-2) and maintains its high catalytic activity after 1000 cycles.
