Abstract
Water-soluble pollutants, especially oil-production related pollutants, are nowadays a major form of public-health-threatening environmental hazard. In this work, we report a new design of Ni based photoelectrocatalyst for the degradation of polyacrylamide (PAM), this particularly malignant by product of oil recovery can be decomposed into harmless product using the proposed method. Specifically, a full spectrum Sn3O4 nanosheet/Ni foam heterostructure photoelectrocatalyst has been developed. The Ni foam not only supports, as a substrate, the Sn3O4 nan-catalyst, but can also interact with the catalyst extending the absorption spectrum into the NIR range. Our heterostructure has exhibited an excellent photoelectrocatalytic activity, resulted from an enhanced efficiency of light harvesting, as well as the more stabilized photogenerated charge pairs, and a higher rate of charge transfer at the interface of hetero-material.
