以MCM-41介孔分子筛为载体制备了纳米氧化铑，并采用XRD、TEM等手段对其进行了表征。H2-TPR和EXAFS。结果表明，水热合成条件对氧化铑颗粒的粒径、位置和结构有很大影响。Rh K边EXAFS研究表明，RhOx的纳米颗粒，尺寸为
Nanoparticles of rhodium oxides were prepared in the MCM-41 mesoporous molecular sieve and were characterized by XRD, TEM. H2-TPR and EXAFS. It was found that the particle size, location and structure of the rhodium oxide particles were greatly influenced by the hydrothermal synthesis conditions. The Rh K-edge EXAFS study revealed that the nanoparticles of RhOx, with the size
