Rational design of TMI active sites in zeolites for redox catalysis

Characterization techniques have long lagged behind the complexity of highly relevant transition-metal-ion exchanged zeolites' (TMI-zeolites) structure and function, impeding fundamental understanding and rational design. Consequently, their commercial adoption remains limited despite promising applications. Advanced characterization techniques are now becoming sufficiently sensitive to shed light into the black boxes of TMI-zeolite catalysis. In parallel, empirical and fundamental knowledge on TMI-zeolite preparation has advanced significantly. The convergence of these two advancements opens the prospect to rational design and preparation of next generation TMI-zeolite catalysts, valorizing knowledge on structure-function relations from spectroscopically validated models. Novel redox catalysts are highly desirable for current challenges including O2 activation, photocatalysis, alkane activation, atmospheric emissions remediation, etc. It is the goal of this PDM to valorize structure-function insight in new TMI-zeolite design.
