Fig. 1: Diffusion-programmed catalysis.
a Schematic illustration of porous heterogeneous catalyst (MOF) in a conventional reaction set up, b diffusion length-dependent turn-over frequency (TOF, solid line) and geometric selectivity (dotted line) profiles for a catalytic reaction; red and green arrow indicate diffusion for A and B reactants, size A > B, the half spheres represent a model porous catalyst particle, c (i) schematic illustration of the diffusion controlled, microfluidic cross-flow reaction set up, (ii) for a catalyst with LC: plausible flow-rate (F) dependent TOF and geometric selectivity profiles, red and green line indicate reactants of different sizes. SP product selectivity. Following are the power laws for (b) and (c) (ii); TOF\(\propto\) 1/LD3 and TOF\(\propto\) 1/F0.5.
