Versuchsvorschrift

Antimony oxalate solution was prepared by mixing antimony (III) acetate as obtained from Aldrich with a 1 M solution of oxalic acid in deionized water and heating the mixture to 60° C. A concentrated solution of ammonium hydroxide in deionized water was added dropwise to the antimony containing mixture until the solution became homogeneous. At this point, the solution was diluted as-required with oxalic acid solution or deionized water to desired metal concentration. The prepared antimony oxalate solution (3.3% antimony, 290.9 μL) was mixed with deionized water (1149.1 μL) and the resultant diluted solution (120 μL) was added to the supported rhodium-indium product of the first impregnation step and agitated by vibration for 30 minutes at room temperature. The obtained trimetallic material was dried at 120° C. for 2 hours and then calcined in air at 450° C. for 4 hours.
