The traditional investigation of complex catalyst poisoning phenomena is in the operation level: poisonings commonly attributed to macroscopic coke deposition and particle size change, etc. Here, we demonstrate that high-resolution SXRD can reveal the structure of the organic molecule–active site complex in a 3-D environment, leading to an understanding of the poisoning mechanism at the molecular level.
