| Abstract | ||||
| IN THIS work pure Ni from different precursors and mixed Ni/Cu, … Ni/Co nano metals were prepared from their chlorides supported on silica from rice straw (RSS) or cation exchange resin (RNa+). The prepared catalysts were characterized by using XRD and TEM. The catalytic activity was tested in H2O2 decomposition. The results revealed that the obtained metals were in nano size. The results of decomposition of hydrogen peroxide showed that the activity of nano nickel catalyst prepared from chloride was more than that from sulfate and nitrate. The most active catalyst among all the prepared samples was Co-Ni/RSS. | ||||
