| Abstract: | The crystals in the hydrogen reduction catalyst for gas phase hydrogenation of aldehydes was analyzed qualitatively by using powder X-ray diffraction analysis method, and the crystalline size of the Copper particles were determined quantitatively by Scherer's method.The phase identification results of crystals in the catalyst are Graphite,Zincite and Copper.The dimension of Cu(111) crystal plane is approximately 10.3 nm calculated by profile fitting of chemometrics.The analytical data can satisfy the requirements of research and development of the catalyst for gas phase hydrogenation of aldehydes. |
