This work has as objective to synthesize different HPA for its use in the mentioned reaction. The main difference respect to previous investigations is that the HPA solution impregnate, by equilibrium impregnating, uses like solvent ethanol for the impregnating of pure silica (S) or functionalized silica (FS), but as well, adds H2O2 to S and water to FS, following to the HPA impregnation. Figure 1a show DRS spectra of different V-HPA
