| Abstract | Silica dispersed copper nanomaterials with high dispersion and unusual thermal stability were prepared by a simple precipitation-gel method, and their physicochemical properties have been characterized by a variety of techniques including FTIR, XRD, XPS, TG-DSC, SEM, TEM, H2-TPR, and N2 adsorption. Both Cu(OH)2 nanoparticles and amorphous copper phyllosilicate are confirmed to present in the dried samples, whereas CuO nanoparticles and undecomposed copper phyllosilicate are determined in the calcined samples. Cu(OH)2 nanoparticles are prone to assemble to wire-like structure during sample preparation, and their structure can be well preserved after calcination and silica dispersed CuO nanowires were obtained. The preparation procedure of precipitation gel is favorable for the formation of copper phyllosilicate, which is rather stable and played a profound effect on both the structure and thermal stability of the samples. In addition, the high dispersion and the one-dimensional structure of copper also contribute to the high stability of the samples. |
