Degradation of 4-nitrophenol and UV–vis absorption spectra. (a) Schematic representation of degradation of 4-nitrophenol from pale yellow into colourless solution in the presence of MBF-Au0 heterogeneous catalyst; (b) UV–vis absorption spectra during the reduction of 4-nitrophenolate ion by Au NPs bound to MBF over a time period of 10 min.
