Surface 4-trifluoromethylphenylacetylene (4-TFMA) functionalization enables inert Cu2O cubes to exhibit a good photocatalytic activity. The modified rhombic dodecahedra also showed enhanced photocatalytic activity, but decorated octahedra actually delivered activity suppression. Scavenging experimen...
