摘要: The photocatalytic O-2 evolution from water oxidation was investigated over a series of WO3 materials treated with hydrogen at different temperatures. activity 200 degrees C can be enhanced to 2.3 times that pristine WO3. surface layer is partially reduced during the treatment, forming kind HxWO3-WO3 composite material. HxWO3 phase possesses high electrical conductivity and plays as reduction cocatalyst for in process. Formation suitable amount could facilitate transfer electrons, leading efficient charge separation resulting enhancement under visible light irradiation. Fabrication semiconductor conductor nanocomposite. might useful strategy development water-splitting photocatalysts. (C) 2013 Elsevier Inc. All rights reserved.
