Photocatalytic Cr(VI) reduction and organic-pollutant degradation in a stable 2D coordination polymer

A novel 2D coordination polymer shows highly photocatalytic activities under UV light, which can reduce Cr(VI) to Cr(III) and decompose organic dyes effectively. Competition of photo-excited electron between Cr(VI) and organic dyes inhibited BUC-21's photocatalytic activities in their matrix.
