Abstract In the current work gold catalysts supported on both commercial oxides and oxides synthesized by the sol-gel method were used for the one-pot alcohol amination of myrtenol. In general, utilization of metal oxides synthesized by the sol-gel method as the gold catalyst support enhanced the knowledge regarding key parameters determining catalytic behavior. Synthesized alumina was characterized by stronger acid sites favoring primary amine accumulation on the catalyst surface, as compared to the commercial oxide. Utilization of mixed metal oxides synthesized by the sol-gel method resulted in the non-additive behavior of different oxides enhancing the catalytic activity. Introduction of ceria into alumina modified the support basicity resulting in more efficient alcohol activation.

Different Characteristics

In this study, powders of BaCe0.54Zr0.36Y0.1O2.95 (BCZY) were synthesized by a sol-gel method assisted with three different groups of chelating agents. The chelating agents used were citric acid, tartaric acid, glycolic acid from carboxylic group, tryelthylenetetraamine (TETA) from polyamino group, nitriloaacetic acid (NTA) and ethylenediaaminetetraacetic acid (EDTA) from polyamino carboxylic group. The samples were dried at 325 °C and calcined at a series of temperatures. The solution and resulting powder properties were studied using Fourier transform Infrared (FTIR) spectroscopy. FTIR spectra showed all the samples exhibit different characteristics of absorption bands after being treated at various temperatures. Such behavior indicates that the chelation process took place before the formation of metal oxide. The chelating agent from polyamino group that consists of N-donor atoms, which is TETA showed no characteristics peak of carbonates was detected after the sample was calcined at 1100 °C. Therefore, TETA gave a significant role in reducing calcination temperature for synthesizing cerate-zirconate powder.
