Continuous Synthesis and Functionalization of Metal Organic Frameworks using Microfluidic Platforms
EMSL Project ID

Abstract
Nanomaterials represent an important class of materials with improved properties and fascinating applications. PNNL has been actively engaged in the utilization of metal organic framework heat carriers (MOHC) nanomaterials that reversibly uptake the working fluid molecules for geothermal heat recovery applications. MOHC offer potential for larger performance boost in thermal vapor- liquid compression cycles for nanofluids. Hydrothermally synthesized cubic shaped MOHC nanoparticles (Figure 1) enhanced adsorption kinetics compared to bulk due to preferred crystal plane interaction. The surfaces of the nano MOHC are covered by a low index facet such as {200}, {020} and {220}. On the other hand, morphology of the nanoparticles, their surface and the crystal planes are known to significantly influence catalytic performance. Replacing currently used irregular shaped nanoparticle based catalyst in refinement of petroleum products, heating-cooling and biomedical applications could potentially enhance the performance thus reducing the cost. Because the nucleation and growth of colloidal nanocrystals are sensitive to experimental conditions (temperature and concentration), industrial production of nanoparticles with controlled morphology is nearly impossible by linearly increasing the volume of the reaction solution. Current state of the art batch synthesis strategies use time-consuming solvothermal or hydrothermal methods. A process for fast-controlled continuous synthesis of colloidal MOF nano-crystals is highly desired.
