%X 本文利用水热法合成了不同形貌的ZnO/g-C<sub>3</sub>N<sub>4</sub>复合材料。对样品进行了XRD和SEM表征，并探索了其气敏性能。结果表明，线状ZnO成功地负载在了g-C<sub>3</sub>N<sub>4</sub>的表面。其中，ZnO/层状g-C<sub>3</sub>N<sub>4</sub>的最佳工作温度比纯ZnO低90℃，在240℃时，对正丁醇具有良好的选择性和稳定性，在50 ppm正丁醇气体中灵敏度达到20.9，表明g-C<sub>3</sub>N<sub>4</sub>不仅降低了ZnO的工作温度，同时优化了其气敏性能。<br />
ZnO/g-C<sub>3</sub>N<sub>4</sub> composites with different morphologies were synthesized by a hydrothermal method. The structure and morphology of the samples were characterized by XRD and SEM. And the gas sensitivity of samples was tested. The results show that linear ZnO successfully loads on the surface of g-C<sub>3</sub>N<sub>4</sub>. The optimal operating temperature of ZnO/layered g-C<sub>3</sub>N<sub>4</sub> is 90？C lower than that of pure ZnO. At its optimal working temperature 240？C, it has good selectivity and stability for n-butanol, and the response to 50 ppm n-butanol reaches 20.9. The results indicate that g-C<sub>3</sub>N<sub>4</sub> not only reduces the working temperature of ZnO, but also optimizes its gas sensitivity.
