Co-Al hydrotalcite containing Cl^– anion has been synthesized by co precipitation method and characterized by powder X-ray diffraction, scanning electron microscopy, FT-IR and thermo gravimetric analyses confirm a hydrotalcite-like structure and catalyse the oxidation of benzyl alcohol to benzoic acid in solvent free condition using TBHP as an oxidizing agent and hydrotalcite can be used recycle 3 times without lost its activity.
