摘要：
Photocatalytic properties of iron hydroxide (FeOOH) particles prepared by a hydrothermal method were estimated under visible-light irradiation. Hydrothermal treatment in the presence of ethanol induced alpha-FeOOH (goethite) formation even under an acidic condition, while the presence of chloride ion led to preferential formation of beta-FeOOH (akaganeite). alpha-FeOOH particles with largest specific surface area showed the highest photocatalytic activity among commercial and prepared FeOOH samples and exhibited total decomposition of acetaldehyde even under visible-light irradiation. The progress of photocatalytic reaction may be due to multi-electron reduction of oxygen over FeOOH particles. (c) 2010 Elsevier B.V. All rights reserved.
