Preparation method of composite hydrolysis hydrogen production material and product obtained by preparation method

The invention discloses a preparation method of a composite hydrolysis hydrogen production material and an obtained product, and the preparation method comprises the following steps: adding graphite oxide into ultrapure water, then adding Co (NO3) 2.6 H2O and NiCl2. 6H2O, and dissolving; adding triethanolamine, uniformly stirring, carrying out ultrasonic treatment, and heating at 80-100 DEG C for 12-15 hours; after cooling, centrifuging and washing the obtained precipitate; drying at 60 DEG C for 6-8 hours; heating to 300-400 DEG C in a nitrogen flow, preserving heat for the first time, then continuously heating to 500-550 DEG C, preserving heat for the second time, and cooling to obtain CoNi-coated CoOx; naBH4 and CoNi coated CoOx are directly mixed in an air environment. The catalyst is good in catalytic effect, and the obtained composite hydrolysis hydrogen production material is good in hydrogen production dynamic performance. 本发明公开了一种复合水解制氢材料的制备方法及其所得产品，包括以下步骤：在超纯水中加入氧化石墨，再加入Co(NO3)2·6H2O和NiCl2·6H2O，溶解；加
