Abstract
Nature accomplishes catalytic process with exquisite control by altering the distribution of active sites in a confining pocket and by regulating the structure of occluded solvents. In such systems, the ubiquitous water may influence reaction rates and selectivity by stabilizing reaction intermediates and transition states via a network of H bonds. Inspired by nature, here we aim at providing quantitative support and mechanistic insight into the role of water-promoting C–C bond formation on an acid catalyst by combining spectroscopic analysis, catalytic reaction measurements, and theoretical calculations. This set of experimental and computational studies reveals that the interaction between water and polar species on the surface generates diverse environments surrounding the active sites that facilitate the reaction. These findings provide an extra dimension for tailoring catalytic phenomena in industrially relevant reactions.
