Research Paper


In this study, nitrogen-doped ZnO (N-doped ZnO) nanocrystallites with a one-dimensional structure were synthesized successfully via an advanced wet chemical technique, and their microstructures were characterized by SEM, HRTEM, XRD, and XPS. The catalytic performance of the as-synthesized samples was evaluated by investigating their effect on the thermal decomposition of ammonium perchlorate (AP) by DSC and TG. Results indicate that the morphologies of N-doped ZnO nanocrystallites mainly depend on the presence of urea in the raw materials. Nanocrystallites with peculiar morphology, in which numerous nanorods with a diameter of 40–50 nm arrange orderly and symmetrically in hollow nanotubes with a diameter of 200–800 nm and thickness of 20–30 nm, can be produced when urea is used as a raw material. The as-synthesized N-doped ZnO sample with peculiar morphology drives the thermal decomposition peak of AP decrease about 163 °C with a strong decomposition heat about 1,325 J/g, and the activation energy also decreases from 178.22 to 93.51 kJ/mol. The enhanced catalytic activity of N-doped ZnO sample can be attributed to oxygen vacancies and other defects induced by the doping of nitrogen.
