Response to Comment on 'Photocatalytic Oxidation Mechanism of As(III) on TiO_2: Unique Role of As(lll) as a Charge Recombinant Species'

摘要

We write in response to the comments from Leng et al. on our paper concerning the role of arsenite as a charge recombinant species in TiO_2 photocatalytic oxidation process.2 They raised three majors issues and our replies are as follows: First, concerning the TDR spectroscopy measurements, they questioned if the laser light intensity was the same. We must state the transient absorption intensity was measured under the same experimental condition. In general, the sample dispersion property may affect the number of absorbed photons in the diffuse reflectance spectroscopy.
