Briefly, 2-MIMand zinc nitrate hexahydrate were separately dissolved in water respectively . After complete dissolution, the zinc nitrate solution was then poured into the 2-MIM solution, and stirred the mixed solution. The white suspension was centrifuged for 10 min, and the precipitant was washed with water for 3 times. The white slurry after centrifugation was vacuum dried in lyophilizer and stored for further use. The procedure to synthesize ZIF-67 nanoparticles was according to previous work with slightly modification. Briefly, 2-MIM and cobalt chloride hexahydrate were dissolved in water respectively. A cobalt chloride contained solution was then poured into a 2-MIM contained solution. The indigo solution was stirred vigorously and collected with centrifugation. The pellet was washed with water and dried for usage. The hollow cobalt oxide nanoparticles was produced from calcination of ZIF-67.金屬有機框架木質素Metal-organic frameworkslignin
