本发明公开了新能源材料技术及电化学催化领域的一种超高性能析氢电解水催化剂的制备方法及应用，将含有金属元素的染料与二氧化钛进行敏化反应，加入石墨烯充分混合，再经高温热解制备出负载超分散金属纳米颗粒N/S共掺杂的碳材料作为析氢电解水的电催化剂，金属纳米粒子粒径为2 nm。在酸性和碱性条件下展示出极其优异的析氢性能，几乎可以和商业Pt/C相媲美，当电流密度为10 mA cm‑2时，在酸性和碱性条件下分别表现出74 mV和13 mV的超低过电势。将该电催化剂应用于电解水，电流密度为10 mA cm‑2时，电位仅为1.52 V，具有优异的电解水能力。本发明的制备工艺简单，成本低廉，催化性能优异，可重复性好，具有很好的理论和实际应用价值。
