The design of heterogeneous catalysts with tunable activity and selectivity constitutes a remarkable challenge. Now, a synthetic approach towards producing nanocrystals encapsulated within polymer layers has been developed, unravelling the principles to achieve control of transition state and product diffusion using CO oxidation as a case study.
