The paper reports the results of a preparation of photocatalysts based on niobium pentaoxide (Nb2O5). These materials have been obtained by calcination of a Nb2O5 precursor with alkali metal hydroxides (Li,Na, K). The obtainedmaterials have been characterized by several methods, i.e., XRD, DR-UV-vis, and FTIR/DRS. The photocatalytic decomposition of phenol as amodel contaminant has been investigated in the presence of all the prepared photocatalytic materials under UV-light irradiation. Of all investigated samples, Na/Nb2O5 has the highest activity.
