摘要：

A new porphyrin-polyoxometalate hybrid nanoparticle was synthesized by the ionic assembly between trans-diaquo[5,10,15,20-tetrakis(4-pyridinium)porphyrinato]tin(110 cation (SnP) and phosphomolybdate anion (POMo) in aqueous solution. UV-vis spectroscopic investigation on SnP-POMo nanoparticles supports that J-aggregation mainly occurs in SnP-POMo rather than H-aggregation. The influences of temperature or pH to the formation of SnP-POMo nanoparticle were examined. DLS measurements revealed that the average hydrodynamic diameter of SnP-POMo in water is ca. 245 nm with narrow distributions in size. The photocatalytic hydrogen production from water by the SnP-POMo sensitization exhibited higher activity than that of SnP under visible light irradiation. (C) 2015 Elsevier B.V.
