Processing strategies for the synthesis of hybrid materials stand as relevant ways to modulate the particle size and morphology. We present herein the use of a continuous high temperature-high pressure (HT-HP) process for the synthesis of a new cerium based metal-organic framework (MOF). The HT-HP harsh thermodynamic synthesis conditions lead to MOF nanostructures exhibiting the same phase as for microparticles obtained under conventional batch solvothermal conditions but in exceptional much shorter residence times, opening avenues towards production scaling-up. The HT-HP process also tailors down the size of the particles, which still presents a major issue for most MOF applications.
