Janus composite particles (JPs) with distinct compartmentalization of varied components thus performances and anisotropic shape display a variety of properties and have demonstrated great potentials in diversify practical applications. Especially, the catalytic JPs are advantageous for multi-phase catalysis with much easier separation of products and recycling the catalysts. In the first section of this review, typical methods to synthesize the JPs with varied morphologies are briefly surveyed in the category of polymeric, inorganic and polymer/inorganic composite. In the main section, recent progresses of the JPs in emulsion interfacial catalysis are summarized covering organic synthesis, hydrogenation, dye degradation, and environmental chemistry. The review will end by calling more efforts toward precision synthesis of catalytic JPs at large scale to meet the stringent requirements in practical applications such as catalytic diagnosis and therapy by the functional JPs.
具有不同成分分区的 Janus 复合粒子（JPs）因此具有不同的性能和各向异性形状，表现出多种性质，并在多样化的实际应用中显示出巨大的潜力。特别是催化 JPs 有利于多相催化，产物的分离和催化剂的回收更加容易。在这篇综述的第一部分，简要综述了具有不同形态的 JPs 的典型合成方法，分为聚合物、无机和聚合物/无机复合材料。在主要部分，总结了 JPs 在乳液界面催化中的最新进展，涵盖了有机合成、加氢、染料降解和环境化学。最后呼吁朝着大规模精确合成催化 JPs 的方向努力，以满足实际应用中严格的要求，如功能 JPs 的催化诊断和治疗。
