Title: | Visible-light sensitization of boron-doped nanocrystalline diamond through non-covalent surface modification | Authors: | Krysova, Hana Vlckova-Zivcova, Zuzana Barton, Jan Petrak, Vaclav NESLADEK, Milos Cigler, Petr Kavan, Ladislav |
Issue Date: | 2015 | Publisher: | ROYAL SOC CHEMISTRY | Source: | PHYSICAL CHEMISTRY CHEMICAL PHYSICS, 17 (2), p. 1165-1172 | Abstract: | A novel simple and versatile synthetic strategy is developed for the surface modification of boron-doped diamond. In a two-step procedure, polyethyleneimine is adsorbed on the hydrogenated diamond surface and subsequently modified with a model light-harvesting donor-pi-bridge-acceptor molecule (coded P1). The sensitized diamond exhibits stable cathodic photocurrents under visible-light illumination in aqueous electrolyte solution with dimethylviologen serving as an electron mediator. In spite of the simplicity of the surface sensitization protocol, the photoelectrochemical performance is similar to or better than that of other sensitized diamond electrodes which were reported in previous studies (2008-2014). | Notes: | [Krysova, Hana; Vlckova-Zivcova, Zuzana; Kavan, Ladislav] Acad Sci Czech Republic, Vvi, J Heyrovsky Inst Phys Chem, CR-18223 Prague 8, Czech Republic.
