In recent years, hydrothermal method has been widely applied on the synthesis of ceria (CeO2) for controlling its nanoshapes (rods, spheres, cubes, tubes, and octahedra). However, there are many challenges to prepare well-dispersed high surface area CeO2 via hydrothermal route, including the particle agglomeration and difficulty to scale up for device development. In this study, we report a facile electrochemical deposition method to fabricate CeO2 nanoarrays on Ti substrate under variable electrochemical conditions. In our preliminary results, a large number of well-aligned CeO2 nanoarrays with controlled density and length-to-diameter ratio were successfully fabricated on Ti foil electrode using a mixture of Ce(NO3)3, KCl and NH4Cl solution as electrolyte, which have showed great potential as catalyst supports for several pollutant gas conversion reactions. |
