Development of highly active and stable electrocatalysts for overall water splitting is important future renewable energy systems. In this study, porous Mn-doped FeP/Co3 (PO4 )2 (PMFCP) nanosheets on carbon cloth are utilized as a efficient 3 D self-supported binder-free integrated electrode the oxygen evolution hydrogen reactions (OER HER) over wide pH range. Specifically, overpotentials 27, 117, 85 mV required PMFCP to attain 10 mA cm-2 HER in 0.5 m H2 SO4 , 1.0 phosphatebuffered saline (PBS), KOH, respectively. addition excellent performance electrocatalysis, were also OER. Thus, can serve anodes cathodes (OWS). The OWS working voltages found be 1.75, 1.82, 1.61 V acid, neutral, alkaline electrolytes, Chronopotentiometric tests show that maintain its pH-universal activity more than 30 000 s. This work provides new insights into developing high-performance improvement electrochemical by introduction Mn dopant nano-holes offers opportunities development effective electrodes other energy-related applications.
