Uniformed polyaniline supported MoS_2 nanorod: a photocatalytic hydrogen evolution and anti-bacteria material

摘要

In this work, low-cost conductive polymer polyaniline (PANI) was confirmed to be a proper substrate of MoS_2, and formed MoS_2/PANI nanorod. The dense and uniform vertical alignment of MoS_2 on PANI substrate, with large amount of active edges exposed and the improvement of electron transfer efficiency, contributes to the excellent photocatalytic activity under visible light. This MoS_2/PANI composite exhibits high photocatalytic performance in the degradation of E. coli and hydrogen evolution under visible light. The high visible-light photocatalytic activity of the MoS_2/PANI composite is ascribed to the increase of surface active centers exposure and charge separation property of PANI.
