摘要：

Nanocomposite of graphitic carbon nitride (g-C3N4) with optimum concentration of multiwall carbon nanotubes (MWCNTs) is shown to render 100% improvement in its photocatalytic activity for visible-light induced water splitting. Our study reveals that in addition to the charge transfer effects, morphological changes in g-C3N4 introduced by mild MWCNT reinforcement play a vital role in the photocatalytic activity. We present results of structural and opto-electronic characterizations in support of these inferences. Copyright (C) 2012, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
