Catalytic CO Oxidation over Au Nanoparticles Loaded Nanoporous Nickel Phosphate Composite

Figure 4

UV-vis spectra of VSB-5 and Au/VSB-5 composite (a). The difference spectra of Au/VSB-5 composite before (b) and after (c) the catalytic reaction with the background correction on that of VSB-5 after the Kubelka-Munk function analyses. The peaks were fitted by using Gaussian function.
