Nano-confinement effects in catalysis

The local environment of a catalyst’s active site plays a critical role in determining the catalyst’s activity and selectivity. We study the effect of chemical and geometrical heterogeneity on transport in nanoporous materials, and employ this in catalyst design. We also research nano-confinement effects induced by local curvature, as witnessed in biological systems, and utilize this in the design of supported homogeneous or nanoparticle-based catalysts with improved activity, selectivity and stability.
