Abstract
A series of transition metal oxides or mixed oxides supported nano-Au catalysts were prepared for the selective oxidation of glycerol to glyceric acid using 3% H2O2. It was found that the composition and structure of supports significantly influenced the catalytic performance of catalysts. The mesoporous trimetal mixed oxide (CuNiAlO) supported nano-Au catalysts were more active in comparison with the others. In the present catalytic system, the highest glycerol conversion was 90.5%, while the selectivity of glyceric acid could reach 72%. Moreover, the catalytic performance remained after 11 times of reaction.
Highlights
Environmental pollution and energy crisis are two major problems in the current world, so the synthesis of biodiesel from natural oils and fats has attracted much attention in recent years
glyceric acid (GLYAC) is an important substance in biochemical research, which can be used in the fields of muscle physiology, pharmaceutical, organic synthesis, etc
It is of high scientific significance and practical value to study the selective oxidation of GLY to produce GLYAC in depth
Summary
Environmental pollution and energy crisis are two major problems in the current world, so the synthesis of biodiesel from natural oils and fats has attracted much attention in recent years. The present production methods of GLYAC are far from satisfactory to meet the requirements of the market, and the price of GLYAC is very high [2,6] It is of high scientific significance and practical value to study the selective oxidation of GLY to produce GLYAC in depth. Were designed for the selective oxidation of GLY [3,4,6,7,8,9,10,11,12,13,14,15,16,17,18] Such catalysts were expensive, they showed irreplaceable high catalytic performance. The roles of composition and structure of support, the and structure of support, the reaction conditions in the catalytic performance of catalysts were reaction conditions discussed in detail. in the catalytic performance of catalysts were discussed in detail
