| 内容記述 | Hollw alumina precursor was prepared by the enzyme-inspired precipitation onto o/w emulsion using urease. Decomposition of urea by urease increased the pH of the solution to hydrolyze aluminum sulfate. The advantages of the enzymatic reaction are that the apparent precipitation rate could be controlled by the enzyme concentration of urease, and that the precipitation could take place without the destruction of emulsion. Hollow particles were obtained at enzyme concentrations ranging between 10 and 50 mg/l. The destruction of the emulsion occurred at enzyme concentrations < 10mg/l while nucleation took place spontaneously in the soluution at enzyme concentrations > 50mg/l. Hollow powders with the phase of pseudo-boeh-mite, maintained their apparent shape after transformation into α-alumina at 1300℃. | |||||||||||||
