Phosphorus-doped MoS^sub 2^ hollow microflakes for enhanced electrocatalytic hydrogen evolution

During this process, the phosphorus atom is engineered into hollow molybdenum disulfide (MoS2) in virtue of a facile and simple hydrothermal synthesis. The hollow flake-like phosphorus-doped MoS2 (MoSP) materials are reported firstly for the electrolytic hydrogen production. The MoSP exhibits stronger excellent electrocatalytic activity than pure MoS2 with a lower onset potential about 31 mV and a smaller Tafel slope about 45 mV per decade due to the enhanced electrical conductivity. Also, the MoSP catalyst shows a good stability. The better electrocatalytic activity is relative with the special flake-like structure and the synergy of S and P double anions relying on the doping of low-electronegative P atoms.
