Özet
The structural properties of iron orthoborate samples prepared by different synthetic approaches were comparatively investigated. The structural properties of the product were characterized by powder XRD, FT-IR, UV-Vis-NIR and SEM methods and the thermal stability was analyzed by the TGA/DTA technique. The room temperature magnetic properties of the product were investigated using the vibrating sample magnetometer technique. Fe2(SO4)3·H2O was used as iron source and H3BO3 and B2O3 were used as boron sources. High temperature solid state synthesis method was used and the experiments were performed at Fe:B = 1:2, 1:3 and 1:4 mole ratios. High purity (99 %) iron orthoborate (Fe3BO6) was obtained from iron(III) sulfate and boric acid at 1:3 ratio. The product was observed to crystallize into orthorhombic crystal structure (Norbergite type) and cell parameters were determined as a = 10.046(2) Å, b = 8.532(2) Å and c = 4.467(1) Å values from ICDD data base. The use of Fe3BO6 in the catalytic reaction for the oxidation of benzyl alcohol under solvent-free conditions was tested without employing any oxidant. Benzaldehyde, dibenzyl ether and benzyl benzoate were observed to be the three main products.
