Synthesis and Characterization of Carbon-Based Composites for Hydrogen Storage Application

Abstract

Recent development shows that carbon-based composites are proving to be the most promising materials in hydrogen energy production, storage and conversion applications. In this study, composites of the copper-based metal-organic framework with different ratios of graphite oxide have been prepared for hydrogen storage application. The developed materials are characterized by X-ray diffraction (XRD), gravimetric thermal analysis (TGA), scanning electron microscopy (SEM) and BET. The newly developed composites have an improved crystalline structure and an increased surface area. The results of the experiment showed that the composite material MOF/GO 20% can store 6.12% of hydrogen at −40 °C.

Synthesis, Properties, and Applications of Metal Organic Frameworks Supported on Graphene Oxide

“…After the GO content reached 20%, functional groups on the deformed graphene layer outnumbered the number of MOF sites that could interact with one another. The experiment findings demonstrated that the MOFs/GO 20% composite material can store 6.12% of hydrogen at −40 • C [77].…”

“…Munir et al [77] produced a composite of copper-based MOFs with various ratios of GO for hydrogen storage applications. A well-dissolved MOF precursor was combined with GO powder to synthesize the composite.…”
