Preparation of photocatalytic titanium dioxide/graphene oxide material from a mixture of coconut shells and potato peels 1010879 2024 G.Z. Kyzas, A.C. Mitropoulos, D.N. Bikiaris, D.A. Lampropoulou, E. Evgenidou The present invention relates to the preparation process of a photocatalytic titanium dioxide/graphene oxide material from a mixture of coconut shells and potato peels. The specific methodology is based on the initial synthesis of graphene oxide from the mixture of coconut shells and potato peels, and the subsequent synthesis of the GO/TiO₂ composite materials. The process yields a final graphene oxide product of high purity (93%) from zero-cost raw materials (coconut shells and potato peels). Thus, the present synthesis enhances the sustainable approach
Production of high-purity graphene oxide from organge peels 1010802 2024 G.Z. Kyzas, D.A. Lampropoulou, D.N. Bikiaris, A.C. Mitropoulos The present invention relates to the preparation process of high-purity graphene oxide from orange peels. The specific methodology is based on the conversion of biomass into graphitic material and, subsequently, into graphene oxide. This process yields a final graphene oxide product of high purity (95%) from zero-cost raw materials. Thus, highly energy-intensive intermediate synthesis steps are bypassed, and the sustainable approach is enhanced.
Acitvated carbon from table sugar 1010189 2022 E. Liakos, G.Z. Kyzas, D.A. Giannakoudakis, A.C. Mitropoulos The present invention relates to a method for the preparation of activated carbon from sugar (sucrose) for use as an adsorbent material. The product exhibits a high specific surface area (BET) of approximately 1756 m²/g. The total production cost does not exceed 2.3€/kg for the composition briefly mentioned in the abstract (H₃PO₄/Sugar, 1/1).
Production of high-purity graphene from lignite 1010267 2022 G.Z. Kyzas, A.C. Mitropoulos The present invention relates to the preparation process of high-purity graphene from lignite. The specific methodology is based on the conversion of lignite into humic acid and, subsequently, into graphene oxide, prior to the synthesis of the final product. This process yields a final graphene product of high purity (77%) from zero-cost lignite, with intermediate products also exhibiting high yields (humic acid at 45% and graphene oxide at 88%). Thus, the present synthesis bypasses highly energy-intensive intermediate steps typically involved in the conventional conversion of lignite to graphene (lignite – carbon – activated carbon – graphite – graphite oxide – graphene oxide – graphene).
Green activated carbon from potato peels and application as adsorbent material for oil-spill cleaning 1009388 2018 G.Z. Kyzas, A.C. Mitropoulos The present invention relates to the preparation process of activated carbon from agri-food residues (potato peels) for application as an adsorbent material in oil-spill cleanup. The product exhibits a high (a) specific surface area (BET) of approximately 1670 m²/g, (b) organic phase adsorption capacity of approximately 10 g/g (g of organic phase per g of material), and (c) swelling capacity of approximately 90%. The total production cost does not exceed 5€/kg.
