Abstract

Dextran and carboxylated dextran biopolymer coating of a range of cobalt, iron and manganese oxide nanoparticles and also reusable biopolymer beads coated with metal oxide nanoparticles are prepared, analysed and evaluated as a means of preserving high surface area co-catalysts for aqueous photocatalytic water oxidations. Stabilization of the nanoparticles is found to inhibit aggregation and allow efficient water oxidations to take place relative to commercial uncoated cobalt oxide nanoparticles. Possible reasons for the relative rates of oxygen production found within the range of functional biopolymer–nanomaterials tested are discussed.
