A novel CZO nanocomposite was synthesized and used as heterogeneous catalyst for transesterification of waste cooking oil into biodiesel using methanol as acyl acceptor. The synthesized CZO nanocomposite was characterized in FESEM with an average size of 80 nm as nanorods. The XRD patterns indicated the substitution of ZnO in the hexagonal lattice of Cu nanoparticles. The 12% (w/w) nanocatalyst concentration, 1:8 (v:v) O:M ratio, 55 °C temperature and 50 min of reaction time were found as optimum for maximum biodiesel yield of 97.71% (w/w). Hence, the use of CZO nanocomposite can be used as heterogeneous catalyst for biodiesel production from waste cooking oil.
一种新型的 CZO 纳米复合材料被合成出来，并作为非均相催化剂，用于将废食用油与甲醇进行酯交换反应，生成生物柴油。所合成的 CZO 纳米复合材料在 FESEM 中进行了表征，平均尺寸为 80nm 的纳米棒。XRD 图谱表明，ZnO 取代了 Cu 纳米颗粒的六方晶格中的位置。12%（w/w）的纳米催化剂浓度、1:8（v:v）的 O:M 比、55°C 的温度和 50min 的反应时间被发现是获得最高生物柴油产率 97.71%（w/w）的最佳条件。因此，CZO 纳米复合材料可用作废食用油生产生物柴油的非均相催化剂。
