Highly efficient and stable MoP-RGO nanoparticles as electrocatalysts for hydrogen evolution

摘要: Abstract Electrochemical splitting of water to obtain hydrogen plays a vital role in high energy density devices, especially for fuel cells. In this work, reduced graphene oxide supported molybdenum phosphide nanoparticles (MoP-RGO) were prepared via facile solvothermal reaction followed by high-temperature phosphating treatment. The electrochemical measurement results indicate that the MoP-RGO nanocomposite obtained at 900 °C exhibits excellent electrocatalytic activity evolution (HER) with overpotentials 117 mV and 150 mV current 10 mA cm −2 acid alkaline media, respectively. Furthermore, instability catalyst basic medium was systemically investigated. This work provides strategy synthesis cost-effective carbon metal as HER electrocatalyst.
