In this paper. expanded graphite was prepared by chemical oxidation system with hydrogen peroxide as oxidant and concentrated sulfuric acid as intercalation agent. Expanded graphite was obtained by microwave expansion. The effects of the amount of hydrogen peroxide and concentrated sulfuric acid on the morphology and specific surface area of expanded graphite were systematically studied. https://www.parisnaturalfoodes.shop/product-category/100-hundo-cacao-bar/
