| Abstract: |
| In order to promote the development of the entire Camellia oleifera industrial chain, pulverized Camellia oleifera shell was employed as templates, and flake calcium carbonate was grown on the debris of Camellia oleifera shell via impregnation/adsorption with Ca2+ and in situ precipitation technique. Then, Camellia oleifera shell carbon loaded calcium oxide was obtained under the condition of high temperature calcination. Next, it was etched partially by nitric acid, and porous calcium Camellia oleifera shell carbon composites were prepared. SEM, XRD and BET characterizations were employed to analyze the prepared materials and samples in process. Meanwhile, their adsorption abilities for methylene blue (MB) were also studied. The results showed that porous calcium Camellia oleifera shell carbon composites had a loosened and porous structure with a high BET surface area of 118 m2/g, and it exhibited decent adsorption ability for MB, and the adsorption ability of the sample calcined at 900℃ was the best. In summary, it can provide novel ideas for the development of high-performance Camellia oleifera shell carbon materials. |
