Photoelectrochemical properties of transparent multilayer films via electrostatic alternating assembly of titanate nanotubes and methylpyridinium porphyrin cobalt
Source abstract
Abstract
Transparent multilayer films of titanate nanotubes (TNTs) and meso-tetrakis (N-methylpyridinium-4-yl) porphyrin cobalt (CoTMPyP) (TNTs/CoTMPyP)n were fabricated by the layer-by-layer self-assembly based on TNTs and CoTMPyP in the aqueous solution. The CoTMPyP molecules as an organic “spacer” and a sensitizer were confirmed to play important roles in the performance improvement of TNTs by comparing with the TNTs multilayer films fabricated with poly(diallyldimethylammonium chloride) (PDDA) as the interlayer. The optical absorption and photocurrent output of the resulting (TNTs/CoTMPyP)n films increased consecutively with the number of the TNTs/CoTMPyP bilayer. The optical and thermal stabilities of the (TNTs/CoTMPyP)12 films were evaluated under UV light irradiation and heat treatment, respectively. The results showed that the UV light irradiation and heat treatment had obvious influences on the photoelectrochemical performance of the resulting films.
