Surprisingly, samples containing vanadium show neither adsorption nor photo-oxidation activity towards the studied dye even after heat-treatment (data not shown). According to HR-TEM images, the glassy matrix in those samples is high, giving an indication that ARQ197 most of the photoactive crystals are obscured under the glass matrix.
