Abstract: Environment-friendly reinforced foam for underground hydrogen storage and a preparation method thereof. The reinforced foam includes hydrogen and a liquid phase, where the liquid phase is an aqueous solution of a foaming agent, a foam stabilizer, a pH regulator and a particle cosolvent; and the foam stabilizer is a compounded system composed of 0-dimensional nanomaterial and 1-dimensional nanomaterial at a mass ratio of 2-5:1. In the reinforced foam of the present disclosure, the 0-dimensional and the 1-dimensional nanomaterials are compounded to form a nano-armor layer, which improves the stability of foam and the interfacial viscoelasticity of a liquid film by synergistic reinforcement, and inhibits the viscous fingering, escape and leakage of hydrogen in a reservoir, thereby not only being beneficial to improving the mobility of hydrogen, but also increasing the safety of hydrogen underground storage.
