1. A method of hydrogen generation from NaBH₄, comprising:

hydrolyzing NaBH₄in the presence of a ZrO₂/CaSiO₃/g-C₃N₄nanocomposite material;

wherein the NaBH₄reacts with water to form H₂gas in the presence of the ZrO₂/CaSiO₃/g-C₃N₄nanocomposite material as a catalyst;

wherein the ZrO₂/CaSiO₃/g-C₃N₄nanocomposite material comprises spherical metal oxide nanoparticles comprising a ZrO₂phase and a CaSiO₃phase dispersed on a matrix of g-C₃N₄nanosheets,

wherein the spherical metal oxide nanoparticles have an average particle diameter in a range from 3 to 18 nm, and

wherein the hydrolyzing proceeds with a hydrogen generation rate of greater than or equal to 200 mL·min⁻¹·g⁻¹.
