dc.description.abstractManganese oxide material shave been studied extensive lydue to their potential applications in a wide variaty of areas. This leads to a searchfor novel methods, which are more efficient and environmentally friently with desired properties to synthesize these materials. This paper reports the novel synthesis of layered manganese oxide with birnessite-type structure using ceramic method. The effect of synthetic parameters such as reductant types, mol rasio of precursor, reaction temperatura and reaction time were studied to optimize the product. As-synthesized products were characterized using X-ray diffraction to determine their structure, phases and crystallinity, while SEM wasusedto determine their morphology. Other characterization includes Gas Sorption Analyzer (GSA) forsurface area and FT-IR foracidity. There sultsindicated that both reductants (Glucose and fructose) led to the formation of birnessite with different purityde pending the condition of reaction. For glucose as reducing agent, the optimum conditions with desired properties were as follows; KMnO4 :glukosa (3 : 1), calcination temperatura of 700°C for 7 hours. The birnessite obtained has the following properties such as flat appereance, particleize of 0.3-2 μm, and surface area of 2,6515 m2/gram. On the other hand, fructose produced the optimum condition with mol rasio of KMnO4 :fruktosa (3 : 1), calcination temperature of 500°C and reaction time of 5 hours with the following properties of birnessite: particlesize of 2,5 – 5 μm, surface area of 2,5781 m2/gram, and acidicsites, Lewis site at 1460 cm-1 and Bronstedsite at 1640 cm-1.en_US
