Photocatalytic activity enhancement with 4-cyanophenylacetylene-modified Cu2O cubes and rhombic dodecahedra and use in arylboronic acid hydroxylation

Inert Cu 2 O cubes become highly active toward dye photodegradation after 4-cyanophenylacetylene functionalization as shown from the emergence of a 4-CNA-derived band in the Cu 2 O band gap. Functionalization also boosts photocatalytic arylboronic acid hydroxylation.
