摘要

In this paper, we demonstrated a simple approach for preparing alpha-Fe2O3 hollow spheres by mixing ferric nitrate aqueous and glucose in 180 degrees C. The glucose was found to act as a soft template in the process of alpha-Fe2O3 hollow spheres formation. Ag/alpha-Fe2O3 hollow nanocomposite was obtained under UV irradiation without additional reducing agents or initiators. Synthesized Ag/alpha-Fe2O3 hollow composites exhibited remarkable catalytic performance toward H2O2 reduction. The electrocatalytic activity mechanism of Ag/alpha-Fe2O3/GCE were discussed toward the reduction of H2O2 in this paper.
