摘要：

Calcination of oxovanadylphthalocyanine at 500-1000 degrees C under an argon atmosphere was performed. Elemental analyses, XRD and TEM measurements revealed that the calcined materials are composed of nano-sized vanadium nitride and carbon clusters. ESR spectral examinations suggested that the calcined materials have a photo-responsive charge separation feature. The decomposition of methylene blue and trimethylhydroquinone in the presence of the material calcined at 900 degrees C was accelerated by visible light irradiation. H, evolution was detected from a mixture of the calcined material and water under the visible light irradiation. (c) 2006 Elsevier Ltd. All rights reserved.
