Engineering the Interface of Ceria and Silver Janus Nanoparticles for Enhanced Catalytic Performance in 4-Nitrophenol Conversion

In this work, we present a modified simultaneous growth and self-aggregation method that produces ceria silver Janus nanoparticles for the conversion of 4-nitrophenol, chemical widely used in several industries. The had cerium-to-silver ratios ranging from 0 to 1.35 well-defined heterodimer morphologies. By controlling conditions, have manipulated interface between silver, maximizing its exposure reactants increasing reaction rate constants 2- 4-fold. Taken together, these results can inform design rules achieve better performing hybrid nanocatalysts.
