Comment on 'Mechanisms for Photooxidation Reactions of Water and Organic Compounds on Carbon-Doped Titanium Dioxide,as Studied by Photocurrent Measurements'

摘要

The title paper by Nakato et al.appearing in a recent issue of this journal studied the mechanisms of photooxidation reactions of water and organic compounds on carbon-doped TiO2 mainly by a method of photocurrent measurements.The paper contains useful experimental data and discussions and is an important contribution to the literature.Unfortunately,however,because the authors overlook many important affecting factors of the photocurrent as it was used for mechanism assessment,I believe that most of their conclusions must be met with some skepticism.
