The invention relates to a preparation method of a porous graphene-zeolite molecular sieve catalyst support. The method comprises the following steps: (1) carrying out hydrothermal reaction on a mixture composed of activated zeolite molecular sieve particles and a graphene suspension in a hydrothermal reaction kettle; and (2) carrying out filtration and drying on the hydrothermal reaction mixture, thereby obtaining the porous graphene-zeolite molecular sieve catalyst support. The preparation method can ensure the porosity of the zeolite molecular sieve, thereby enhancing the gas adsorption and separation effects on gas in chemical reaction, and further being beneficial to the high-efficiency proceeding of the catalytic reaction. 本发明涉及种多孔石墨烯-沸石分子筛催化剂载体的制备方法，包括如下步骤：(1)将已活化的沸石分子筛颗粒与石墨烯悬浮液的混合物在水热反应釜中进行水热反应；(2)对水热反应后的混合物进行过滤、干燥，即得多孔石墨烯-沸石分子筛催化剂载体。本发明的制备方法，可保证沸石分子筛的孔隙率，这能提升化学反应中气体吸附和分离孔隙的效果，进而有利于催化反应的高效进行。
