Abstract In this work, we report an in-situ preparation of Ag/CeO2 anchored on reduced graphene oxide (rGO) nanocomposite. The Ag/CeO2-rGO is considered to be a simple, recyclable, and durable photocatalyst for esterification of aldehydes at room temperature under visible light irritation. It was found that the 2–5 nm-sized Ag-nanoparticles decorated on CeO2 with a size 10–30 nm along with the surface of reduced graphene oxide. The as-synthesized nanocomposite exhibited a higher conversion rate and best selectivity headed for the ester as a major product with 86% conversion of aldehyde and 99% selectivity.

用 Ag/CeO2 纳米复合材料装饰的还原氧化石墨烯对醛的室温光催化酯化

摘要 在这项工作中，我们报告了一种原位制备的固定在还原氧化石墨烯 (rGO) 纳米复合材料上的 Ag/CeO2。Ag/CeO2-rGO 被认为是一种简单、可回收且耐用的光催化剂，用于室温下可见光刺激下醛的酯化。发现 2-5 nm 尺寸的 Ag 纳米颗粒装饰在尺寸为 10-30 nm 的 CeO2 上以及还原氧化石墨烯的表面。合成的纳米复合材料表现出更高的转化率和最佳选择性，以酯为主要产物，醛的转化率为 86%，选择性为 99%。
