	采用简单的温和水热法制备了具备特殊形貌的ZnO纳米花材料，并对其进行了稀土Ce掺杂，利用SEM、XRD、EDX、N2吸附–脱附、紫外可见分光光度法等手段对催化剂进行了表征，并研究了其对罗丹明B光催化降解的动力学性能和机理。结果表明，ZnO纳米花催化反应速率是普通ZnO纳米结构的2.6倍，掺杂了2%的Ce-ZnO催化反应速率比掺杂前又提高了1.6倍，说明催化剂结构优化和稀土元素掺杂的功能修饰策略可有效提高ZnO的光催化活性。<br />
A ZnO nanoflower with special morphology was prepared by a simple mild hydrothermal method and further Ce-doped. The catalysts were characterized by SEM, XRD, EDX, N2 adsorption-desorption, UV-vis, and their kinetic properties and mechanism of photocatalytic degradation of rhodamine B were studied. The results show that the catalytic rate of ZnO nanoflowers is 2.6 times that of ordinary ZnO nanostructures, moreover the rate of 2% Ce-ZnO is 1.6 times higher than that before doping. The structure optimization and rare earth element-doped strategies can effectively improve the photocatalytic activity of ZnO.
