Amino group promoted photocatalytic hydrogen evolution activity observed in two copper()-based layered complexes
Two copper( ii )-based layered complexes with or without the amino group, [Cu(HL) 2 (NH 2 -BDC)] n ( 1 ) and [Cu(HL) 2 (BDC)] n ( 2 ) (HL = 4′-(4-hydroxyphenyl)-4,2′:6′,4′′-terpyridine, NH 2 -H 2 BDC = 2-amino-1,4-benzenedicarboxylic acid and H 2 BDC = 1,4-benzenedicarboxylic acid), were solvotherma...

The amino group effect of the photocatalyst on the catalytic activity of water splitting was investigated under visible light irradiation. The hydrogen production rate of the amino group modified layered complex is almost double that without the amino group. |
