The assembly of diverse active materials significantly enhances the efficiency electrocatalytic hydrogen evolution reaction (HER). Herein, we prepare a three-phase composite structure electrocatalyst on carbonized wood, in which molybdenum carbide and phosphide are attached to sulfide nanosheets (MoS2-MoP-Mo2C@CW) through hydrothermal method combination with high-temperature calcination for pH-universal HER. MoS2 possesses abundant unsaturated coordination edge sites, thus facilitating adsorption desorption intermediate (H*). synergistic effect between MoS2, MoP featuring favorable electronic conductivity, Mo2C holding strong H* catalytic activity Moreover, wood hierarchical porous aligned microchannels accelerates mass transport during As result, molybdenum-based self-supported electrode exhibits outstanding HER performance low overpotentials 46, 84, 65 mV achieve current density 10 mA cm-2 corresponding Tafel slopes 57, 111 mV, 63 dec-1 alkaline, neutral, acidic environments, respectively. MoS2-MoP-Mo2C@CW also shows long-term durability 200 h over broad pH range at cm-2. This work provides an effective strategy development multiphase wood-based electrocatalysts
