The nanomaterial was characterized by TEM, SEM, FT\u2010IR, diffuse reflectance, fluorescence, NMR, DLS, XRD and XPS. These analyses confirm the covalent linking of AQ\u2212COOH with the NH<jats:sub>2<\/jats:sub> functionality in the nanomaterial and, more importantly, the photocatalyst retains its photophysical properties once bound. The heterogeneous photocatalyst was successfully employed in the aerobic hydroxylation of arylboronic acids to phenols under sustainable reaction conditions. Phenols were obtained in high yields (up to 100\u2009%) with low catalyst loading (3.5\u2005mol\u2009%), reaching TOF values of 3.7\u2005h<jats:sup>\u22121<\/jats:sup>. Using 2\u2010propanol as solvent at room temperature, the visible light photocatalysis produced H<jats:sub>2<\/jats:sub>O<jats:sub>2<\/jats:sub> as a key intermediate to promote the aerobic hydroxylation of arylboronic acids. The heterogeneous photocatalyst was reused at least 5 times, without modification of the nanomaterial structure and morphology. This simple heterogeneous system showed great catalytic activity under sustainable reaction
