| description | The strong binding energy of Pt with oxygen intermediates results in its low OER efficiency at the anode. Herein, Pt-doped CoFeP (Pt-CoFeP) material has been synthesized using CoFe-PBA as precursor through facile etching and phosphating processes. Interestingly, Pt-CoFeP with hollow cage framework exhibits large surface area after etching, which plays a domain-limiting role for the high dispersion of platinum atoms and facilitates the oxygen evolution reaction (OER). The target sample Pt-CoFeP only needs low overpotentials of 311.7 and 343.1 mV to deliver the current density of 10 and 50 mA cm-2, which is superior to commercial RuO2. The excellent activity can be attributed to large specific surface area in hollow framework and highly dispersed platinum atoms. And its great durability is evaluated through chronoamperometry measurement for 12 hours. This work provides a potential method to design electrocatalysts with complex structure loaded with highly dispersed Pt particles derived from Prussian blue analogues (PBAs) for water splitting. |
