Gold nanoparticles are deposited on basic CaO supports as catalysts for the selective conversion of styrene into styrene oxide. Synthetic methods, gold loading and calcination temperatures are varied to permit an understanding of their influence on gold nanoparticle size, the presence of cationic gold species and the nature of interaction between the gold nanoparticles and the CaO support. Based on these studies, optimal conditions are designed to make the Au/CaO catalyst efficient for the selective epoxidation of styrene.
金纳米颗粒沉积在碱性 CaO 载体上作为催化剂,用于选择性将苯乙烯转化为苯乙烯氧化物。改变合成方法、金负载量和煅烧温度,以了解它们对金纳米颗粒尺寸、阳离子金物种的存在以及金纳米颗粒与 CaO 载体之间相互作用的性质的影响。基于这些研究,设计了最佳条件,使 Au/CaO 催化剂对苯乙烯的选择性环氧化具有高效性。
