Zhang, Y. & Li, X. (2019). Preparation of Al2O3 hollow microsphere via calcining carbon template and its adsorption application. Chemical Physics Letters, 731 136589-1-136589-6.


Carbon microsphere was synthesized from glucose via hydrothermal method, and then alumina hollow microsphere was prepared using carbon template. At reaction time of 6 h, the carbon sphere displayed uniform diameter of 800 nm. After removal of carbon core during calcination, it obtained 600 nm of γ-Al2O3 hollow sphere with shell thickness of 80 nm and surface area of 186 m2/g. For adsorption of methylene blue, material exhibited adsorption capacity of 26.5 ± 1.2 mg/g, fitting well with Langmuir isotherm. It is demonstrated that calcining carbon template was an effective and facile approach to obtain hollow sphere material.
