Preparation and characterization of H1–e rhodium films
Preparation and characterization of H1–e rhodium films
Mesoposous films of rhodium were prepared by electrochemical deposition from rhodium (III) chloride dissolved in the H1 lyotropic liquid crystalline phase of octaethyleneglycol monohexadecyl ether (C16EO8) or Brij® 56. Characterization of the electrochemically deposited films using SEM, TEM, small angle X-ray diffraction and cyclic voltammetry show that they are smooth, strongly adherent, with a high surface area (32 m2 g?1) and containing a regular hexagonal array of cylindrical pores with a pore centre to pore centre separation of around 6 nm. Preliminary studies show that the films can be used to carry out the electrochemical reduction of nitrate in basic solution.

Abstract
Mesoposous films of rhodium were prepared by electrochemical deposition from rhodium (III) chloride dissolved in the H1 lyotropic liquid crystalline phase of octaethyleneglycol monohexadecyl ether (C16EO8) or Brij® 56. Characterization of the electrochemically deposited films using SEM, TEM, small angle X-ray diffraction and cyclic voltammetry show that they are smooth, strongly adherent, with a high surface area (32 m2 g?1) and containing a regular hexagonal array of cylindrical pores with a pore centre to pore centre separation of around 6 nm. Preliminary studies show that the films can be used to carry out the electrochemical reduction of nitrate in basic solution.
