Blue-shift in Bi-impregnated mesoporous silicas

In this NJC Hot Article, Thomas Maschmeyer and his colleagues (University of Sydney and University of New South Wales, Australia) report on the incorporation of bismuth in TUD-1-type mesoporous silicas. These materials were prepared with different Bi loadings and the silicas were fully characterized. The most interesting finding is the unprecedented blue shift observed in the diffuse reflectance that is attributed to different species of Bi.
