Epoxides are highly useful intermediates in the production of many chemicals, pharmaceuticals, perfumes, and polymers. In view of the continuing demand for epoxides, it is imperative to develop greener and sustainable reaction protocols. To address these challenges, highly active, selective and efficient heterogeneous catalysts have been designed. Historically, there has been a progressive replacement of hazardous peracids and chlorohydrin-based epoxidation of olefins by metal catalysts deploying tert-butyl hydroperoxide (TBHP), hydrogen peroxide (H₂O₂) and molecular oxygen (O₂) as oxidants. The main focus of this review is to epitomize the wide scope of supported metal nanocatalysts that have been applied for the epoxidation of olefins. The synthesis, activity and selectivity of the nanocatalytic materials along with a critical appraisal of the performance of the support in the epoxidation of olefins are accentuated.

支持的非均相纳米催化剂用于烯烃的可持续，选择性和生态友好的环氧化

环氧化合物是许多化学药品，药物，香料和聚合物生产中非常有用的中间体。考虑到对环氧化物的持续需求，必须开发更绿色和可持续的反应方案。为了应对这些挑战，已经设计了高活性，选择性和有效的非均相催化剂。从历史上看，通过部署叔丁基过氧化氢（TBHP），过氧化氢（H ₂ O ₂）和分子氧（O ₂）作为氧化剂。这篇综述的主要重点是概括已应用于烯烃环氧化的负载型金属纳米催化剂的广泛范围。纳米催化材料的合成，活性和选择性以及对烯烃环氧化中载体性能的严格评估得到了强调。
