<i>In‐situ</i> ATR‐IR Spectroscopy Reveals Complex Absorption‐Diffusion Dynamics in Model Polymer‐Membrane‐Catalyst Assemblies (PCMA)

The Front Cover shows the interplay between chemisorption of carbon monoxide probe molecules and diffusion through a porous catalyst with stimulus responsive polymeric brushes that can switch transfer process ON- OFF temperature. In their Research Article, M. J. Enes da Silva et al. showed on Polymer-Membrane-Catalyst Assembly (PCMA) system consisting PET membranes well-defined pore structure coated thermo-responsive polymer (poly(n-isopropylacrylamide) or p-NIPAM) coupled to an in-situ ATR-IR cell molecular is only diminished at temperatures above LCST when located surface pores. This was attributed sluggish high in which forms dense layer top entrance. Surprisingly, opposite trend observed primarily walls this scenario, acts as sink for depending polymer-reactant affinity additional barrier transport induced by polymer.
