摘要

Cross-linked porous polymeric complexes with exposed metal sites are synthesized for room temperature hydrogen storage via physisorption. At 298 K and 100 atm, PTF-Cr exhibits high excess hydrogen storage capacity up to 1.5 wt% with Qst of 11.5 kJ mol(-1) while PTF-Mg exhibits 0.5 wt% with Qst of 8 kJ mor(-1). The result provides insight for development of future storage materials with exposed transition metals.
