IV.C.3 Hydrogen Trapping through Designer Hydrogen Spillover Molecules with Reversible Temperature and Pressure-Induced Switching

Synthesize designer microporous metal-organic • frameworks (MMOFs) mixed with catalysts to enable H-spillover for H2 storage at 300 K to 400 K and moderate pressures. Adapted volumetric measurements to enable rapid • screening tests (RSTs) at high-pressure, towards Go/No-Go decision point. Validate RSTs against published activated carbon and spillover materials at P<80 bar and 298 K. Use RST to down-select MMOFs and determine • effect of structure and surface chemistry. Explore methods for pressure-induced hydrogen/gas • trapping.
