Light-induced hydrogen evolution in oxidising media promoted by catalytic sites encapsulated by phospholipid membranes
Abstract
Encapsulation of the well known photochemical system consisting of electron donor [ethylenediaminetetra-acetic acid (EDTA)], photosensitizer [Ru(bpy)32+(bpy = 2,2′-bipyridine)], electron acceptor [Rh(bpy)33+], and catalytic sites (Pt particles, produced by reduction of K2PtCl4) in a DPPC (dipalmitoyl-D,L-α-phosphatidylcholine) membrane allows light-induced H2 evolution in the presence of an oxidant [K3Fe(CN)6] in the bulk solution.
