NOVELTY - In-situ synthesizing of iron-cobalt complex represented by (I) composite material comprises (1) mixing iron source, cobalt source and graphene oxide solution, formulating into a solution, adding phytic acid to the solution and mixing evenly to obtain a reaction solution, (2) subjecting reaction solution to high-temperature hydrothermal reaction, centrifuging and drying in sequence to obtain a precursor and (3) calcining the precursor to obtain composite material. USE - The in-situ synthesizing of iron-cobalt complex represented by (I) composite material is useful for electrocatalytic hydrogen evolution reaction (claimed). ADVANTAGE - The material is more safe than red phosphorus, white phosphorus and other materials; increases the contact area between the FeP active center and the CoP active center and water, and to make the electrocatalytic hydrogen evolution reaction more active. DETAILED DESCRIPTION - In-situ synthesizing of iron-cobalt complex represented by Fe xCo 1-xP-RGO composite material comprises (1) mixing iron source, cobalt source and graphene oxide solution, formulating into a solution, adding phytic acid to the solution and mixing evenly to obtain a reaction solution, (2) subjecting reaction solution to high-temperature hydrothermal reaction, centrifuging and drying in sequence to obtain a precursor and (3) calcining the precursor to obtain composite material An INDEPENDENT CLAIM is also included for iron-cobalt complex represented by Fe xCo 1-xP-RGO composite material.
