Reduction of MB with sodium borohydride and PA66/Au NP hydrid materials. (a) UV-Vis absorbance spectra of MB reduced by NaBH4 and catalysed with PA66/Au NP microspheres in the wavelength range of 400 to 800 nm. (b) Plots of the relative absorbance of MB absorption peak at 664 nm as a function of the reaction time.
