ZIF-67 as one kind of zeolitic imidazolate frameworks was synthesized by a conventional precipitation method, and the mother liquor was concentrated and crystallized to recover cobalt-based compounds. For AB hydrolysis, two kinds of Co3O4 catalyst precursors (i.e., Co3O4-S and Co3O4-L) were prepared from the ZIF-67 and recovered compounds via calcination treatment, respectively. The morphology and phase composition of the samples were characterized by field-emission scanning electron microscopy and X-ray diffraction, respectively. Effects of AB and catalyst concentration and reaction temperature on the hydrogen generation rates and kinetics were investigated. The results show that Co3O4-S has a porous and polyhedral structure, and Co3O4-L is composed of nanoparticles. In addition, increasing AB and catalyst concentration can enhance the hydrogen generation rates. The maximum hydrogen production rates do not decline in the presence of Co3O4-S, but decrease to 78% of the initial level in the presence of Co3O4-L after recycling for four times.
