Al2O3 material with cribrate tubular structure was prepared by absorbent cotton as moldboard through immersion method and was clipped chemically by HBr acid solution of different concentration. The catalyst Al2O3-AlBrx with controlled activity, adjustable specific surface area and different feature was prepared successfully, and was characterized by scanning electronic microscope and X-ray diffraction. Results show that the catalyst good copy the macroscopic and microscopic structure of cotton fiber and shows the characteristics of obvious biological morphology. Under lighting condition, we found that Al2O3-AlBrx-3 is available for the oxidation of alcohol to corresponding aldehyde, ketone or acid with higher conversion and selectivity using air as an oxidant and proposed a plausible mechanism. Al2O3-AlBrx-3 was recyclable using three times still maintaining high catalytic activity.
