Mechanisms underlying the nucleation processes of mesoporous ceria nanoparticles

Mesoporous ceria nanoparticles featuring ordered pores (O-MCNs) have much greater potential than their counterparts featuring interparticle pores (I-MCNs) due to their uniform pore size and interconnected framework structures. However, current methods can only synthesize I-MCNs and fail to achieve O-MCNs. Understanding the mechanisms underlying the formation of pores in I-MCNs can spark ideas for designing new methods to realize the synthesis of O-MCNs. In this study, the details of an established I-MCN synthetic method using 1-octadecene (ODE) and ethanol as a mixed solvent, Ce(NO
