摘要：

Three hydroxyapatite (HAP) supported rhodium catalysts (i.e., Rh/HAP-PEG-200, Rh/HAP-EDTA-200, and Rh/HAP-EDTA-100) were prepared by loading Rh(NO3)3 onto HAP supports prepared hydrothermally at 200 or 100 degrees C in the presence of PEG or EDTA additive, followed by calcination at 500 degrees C. For comparison, an additional Rh/HAP-normal catalyst was prepared using a conventional HAP support prepared by precipitation. Different preparation methods/conditions were found to influence the physicochemical properties (e.g., micro-morphology, basicity, concentration of surface hydroxyls, oxygen-desorption property) of HAP supports and/or Rh/HAP catalysts. The activities of these catalysts in N2O decomposition follow the sequence of Rh/HAP-PEG-200 > Rh/HAP-EDTA-200 approximate to Rh/HAP-normal > Rh/EDTA-100. The correlation among preparation methods/conditions, physicochemical properties, and catalytic performance of Rh/HAP catalysts was investigated in detail. (C) 2016 Elsevier B.V.
