The invention discloses an MOFs composite hydrogen storage material based on 3D printing and a preparation method and application of the MOFs composite hydrogen storage material in marine hydrogen storage, and the preparation method of the MOFs composite hydrogen storage material comprises the steps that expanded graphite and activated carbon are evenly mixed, formed, ball-milled and sieved to prepare a carbon-based material mixture with the even particle size; adding the carbon-based material mixture into an MOFs precursor solution for crystallization and purification to obtain a carbon-based material (at) MOFs; then uniformly mixing the carbon-based material coated MOFs with a solvent and polyvinyl alcohol to form printing slurry, and preparing the MOFs composite hydrogen storage material through 3D printing of the printing slurry; the pore channel structure of MOFs is changed through 3D printing, the hydrogen storage performance of the MOFs is improved, the structural strength and the heat conduction performance of the MOFs are enhanced, and therefore the hydrogen storage material and system matched with the ship hydrogen fuel power system are researched and developed.

    本发明公开一种基于3D打印的MOFs复合储氢材料及其制备方法及其在船用储氢的应用,其中MOFs复合储氢材料的制备包括将膨胀石墨与活化炭经均匀混合、成型、球磨和过筛,制备出粒度均匀的碳基材料混合物后,将所述碳基材料混合物加入至MOFs前驱体溶液中进行晶化、提纯,得到碳基材料@MOFs;随后将所述碳基材料@MOFs与溶剂、聚乙烯醇均匀混合,形成打印浆料,通过3D打印所述打印浆料制备MOFs复合储氢材料;本发明采取由3D打印改变MOFs的孔道结构,提高其储氢性能、增强结构强度和导热性能,由此研发与船舶氢燃料动力系统适配的储氢材料与系统。
