Modulated synthesis of chromium-based metal-organic framework (MIL-101) with enhanced hydrogen uptake

Comparison of MOF-5- and Cr-MOF-derived carbons for hydrogen storage application

“…On the other hand, the XRD pattern and SEM images of Cr-MOF shown in Figure 2 corresponded well with those earlier reported in the literature [18]. The Cr-MOF derived carbons samples produced at different temperatures MDC-600, MDC-700 and MDC-800 The mass loss observed from the derived carbons from the Cr-MOF (Figure 3a) was relatively lower when compared to that of pristine Cr-MOF and this can be explained by the structural changes that were induced by the carbonisation process.…”

“…was confirmed by XRD spectra as previously reported [17,18]. The SEM images showed nearly regular cube shaped crystals.…”

“…The synthesis procedure for producing MIL-101 was previously reported [18]. Typical experiments were conducted using a 250 ml Teflon-lined Berghof high-pressure reactor (Heizüng, Germany).…”

Hydrogen storage in Zr-fumarate MOF

“…Even though formic acid was previously reported in the synthesis of Zr-fum MOF [17,18], Zr-MOF [23] and Cr-MOF [24], no hydrogen storage measurements were conducted on formic acid-modulated Zr-fum MOF. Therefore, in this study Zrfum MOF was synthesized in a water-based system using formic acid as a reaction modulator, and then hydrogen uptake performance was evaluated.…”

Tuning Defects to Facilitate Hydrogen Storage in Core-shell MIL-101(Cr)@UiO-66(Zr) Nanocrystals

“…The seeding MIL-101 crystals were prepared by following a previously reported procedure with reaction time of 8 h [17]. The pure UiO-66 sample was synthesized according to another previously reported procedure [18].…”
