Since the discovery of catalysis, the identification of the different species in the mechanism involved in the reaction has been a challenge. When nanocatalysis entered the scene, the detection of material that came out from solutions attracted the attention and raised several questions: was this solid part of the nanocatalyst? was it the precursor of the nanocatalysts (the so-called precatalyst)? or was it the nanocatalyst itself? The discussion focuses on whether the catalysis is determined by the species that exist in solution or if it is generated from the support and hence the catalytic reaction is carried out with these soluble species. Furthermore, it appears that leaching is a phenomenon which occurs mainly in palladium- catalyzed reactions and that involves palladium nanoparticles (NPs). The research, findings and patents in the leaching process in catalytic reactions are reviewed in the present paper.
自催化作用被发现以来，确定反应中涉及的不同物种一直是一个挑战。当纳米催化进入人们的视野时，从溶液中检测出的物质引起了人们的关注，并提出了几个问题：这是纳米催化剂的一部分吗？它是纳米催化剂的前体（所谓的前催化剂）吗？还是纳米催化剂本身？讨论的焦点是催化作用是由溶液中存在的物质决定的，还是由载体决定的，因此催化反应是由这些可溶性物质进行的。此外，似乎浸出是一种主要发生在钯催化反应中的现象，涉及钯纳米粒子（NPs）。本文综述了催化反应中浸出过程的研究、发现和专利。
