Popis: A strategy for synthesizing the ordered mesoporous hybrid silica-carbon materials with moderate pore volume and surface area are developed from the dry leaves powder of Tectonagrandis (TG) as carbon precursor by direct carbon loading method. Pre-activated carbon (PAC) has been generated from the dry leaves powder of TG by sulphuric acid assisted partial chemical activation method. The carbon content in silica matrix of the material is fixed up to 50 weight percentages with respect to silica which renders a novel and highly ordered hybrid Si/C mesoporous material by this direct carbon loading strategy. The physical-chemical analyses are supported that the synthesized hybrid Si/C materials are completely different from carbon coated hybrid Si/C materials. Among the synthesized materials, high surface area containing Si/C material has been chosen for dye adsorption which exhibits an excellent dye adsorption behavior with Methylene Blue (MB) dye up to 97% in short span of time.
