Step‐Associated Cu‐Ceria Interfaces Enhance Catalytic Activity and Selectivity
Angewandte Chemie, EarlyView.The catalytic activity and selectivity of supported Cu nanoparticles depends on their interfacial environments, with Cu nanoparticles at step‐associated environments converting CO2 to methanol much faster than those on terrace facets, indicating that step sites create more active metal–oxide interfaces.

Tuning Branching in Ceria Nanocrystals [PDF]
Chemistry of Materials, 2017 Branched nanocrystals (NCs) enable high atomic surface exposure within a crystalline network that provides avenues for charge transport. This combination of properties makes branched NCs particularly suitable for a range of applications where both interaction with the media and charge transport are involved.
