Abstract—

ZnO nanoparticles with different sizes were prepared by varying molar ratio of tartaric acid and zinc nitrate hexahydrate as fuel and oxidizer (F/O) at 0.00, 0.25, 0.50, and 1.00 (0.0000, 0.0025, 0.0050, and 0.0100 mol tartaric acid) by tartaric acid solution combustion method and followed by calcination at 600°C for 2 h. Effect of molar ratio of F/O on phase, morphology and photocatalytic activity of as-prepared ZnO samples were characterized by X-ray powder diffraction, Raman spectroscopy, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In this research, all samples were composed of wurtzite hexagonal ZnO nanoparticles with different sizes controlled by the content of tartaric acid. The photocatalytic properties of samples were also investigated through photodegradation of methylene blue (MB) under UV light irradiation. ZnO nanoparticles for F/O ratio of 1.00 show the highest photodegradation of MB under UV light irradiation.

酒石酸溶液燃烧法合成ZnO纳米粒子及其光催化性能

摘要-

通过改变酒石酸和硝酸锌六水合物作为燃料和氧化剂（F / O）的摩尔比为0.00、0.25、0.50和1.00（0.0000、0.0025、0.0050和0.0100 mol酒石酸）来制备具有不同尺寸的ZnO纳米颗粒酒石酸溶液燃烧法，然后在600°C下煅烧2小时。通过X射线粉末衍射，拉曼光谱，傅立叶变换红外光谱，扫描电子显微镜和透射电子表征了F / O摩尔比对制备的ZnO样品的相，形貌和光催化活性的影响。显微镜（TEM）。在本研究中，所有样品均由酒石酸含量控制的不同尺寸的纤锌矿型六角形ZnO纳米颗粒组成。还通过在紫外线照射下亚甲基蓝（MB）的光降解研究了样品的光催化性能。F / O比为1.00的ZnO纳米颗粒在紫外光照射下具有最高的MB光降解性能。
