摘　　要：本工作通过溶胶-凝胶-燃烧法在不同的双功能络合剂——乙醇胺(MEA)、柠檬酸(CA)或乙酰丙酮(ACAC)辅助下制备了(002)取向的掺铝氧化锌(AZO)粉末。对所制备粉末的物相结构、形貌和光学性能进行表征,进一步利用所制备的AZO粉末对亚甲基蓝溶液(MB)进行光催化降解研究。结果表明:采用不同的络合剂时,所有样品均为沿(002)方向择优取向的AZO粉末;其中以ACAC作络合剂时制备的AZO粉末呈粒径27.8 nm左右的球形结构,禁带宽度为3.129 eV,光致发光强度优于其他两种粉末,降解MB溶液的效率可达98%。In this work,(002)oriented aluminum-doped zinc oxide(AZO)powder had been prepared with different bi-functional complexing agents-ethanolamine(MEA),citric acid(CA),or acetylacetone(ACAC)via the sol-gel-combustion method.X-ray powder diffraction(XRD),scanning electron microscope(SEM),UV-Vis spectroscope(UV-Vis)and photoluminescence spectroscope(PL)were applied to characterize the phase structure,morphology,and optical properties of the AZO prepared.Furthermore,these AZO powders were evaluated in the photocata-lytic degradation of methylene blue solution(MB).The results showed that when different complexing agents were used,all powder products had the same pure phase structures of AZO with preferred orientation along the(002)direction;the AZO powder prepared with ACAC as the comple.xing agent demonstrated spherical particles with a particle of 27.8 nm,a bandgap width of 3.129 eV,and it’s photoluminescence intensity was superior to the other two powders.It's efficiency of MB degradation solution could reach 98%.
