该研究论文探讨了稀土氧化物对CuO-CeO2/γ-Al2O3/Cord催化剂性能的影响。作者们采用了溶胶-凝胶法制备稳定的α-AlOOH溶胶,并在此基础上引入La、Y、Nd、Pr、Ce等不同的稀土氧化物,对蜂窝陶瓷载体进行表面改性。以CuO-CeO2作为活性组分,制作出新型催化剂,目的是提高其在CO选择性氧化过程中的性能。 通过色谱流动反应法、H2-TPR(氢二聚体升温还原法)以及XRD(X射线衍射)等测试手段,研究者发现添加La2O3、Y2O3和Ce2O3显著提高了催化剂的活性,尤其是在添加Y2O3的情况下,即使在175℃这样的较高温度下,催化剂的选择性仍能保持在90%,这对于CO的选择性氧化过程来说是非常重要的优化结果。这种改进对于燃料电池应用中的氢源问题有潜在的解决方案,因为高效去除CO可以减少对质子交换膜燃料电池性能的影响,延长其使用寿命。 整体式催化剂因其床层压力低、催化效率高和放大效应小等特点,在化工领域得到了广泛应用。因此,将CuO-CeO2催化剂与活性氧化铝涂层结合,添加稀土氧化物,制成适合实际工业应用的高效整体式催化剂,是未来的研究重点。这项研究不仅提升了催化剂的性能,也为解决燃料电池中CO污染问题提供了新的途径,推动了清洁能源技术的发展。
