Preparation and Catalytic Degradation of Methyl Orange on Aluminium Ion Doped Neodymium Zirconate Nanocrystals
Nd2−xAlxZr2O7 nanocrystals al-ready fully formed with the heat treatment temperature in 700°C. The obtained nanocrystals were consisted of spheroidal particles with the average grain size of 10 - 30 nm. According to the Scherrer formula, the calculated mean grain size is 14.5 nm. The crystal plane distance from the (222) plane in the photo of transmission electron microscopy is 0.305 nm, which is consistent with the theoretical calculated value. The catalytic activity of the composite product is determined by the reaction speed of photocatalytic degradation of methyl orange. It is detected that compared to Nd2Zr2O7, the doping of Al3+ can obviously improve its catalytic performance. When nAl:nNd = 1:19, it has the strongest catalytic activity.
