“…However, it was concluded that none of those conventional adsorbents showed sufficient CH4 storage capacity to meet that required for commercial viability (Saha et al, 2010). Advanced materials have been investigated as potential CH4 adsorbents including modified activated carbons, metal-organic frameworks (MOFs) and other porous polymers (Kizzie et al, 2014).…”

Innovative gas capture technologies with the objective to mitigate CO and CH emissions are discussed in this review. Emphasis is given on the use of nanoparticles (NP) as sorbents of CO and CH, which are the two most important global warming gases. The existing NP sorption processes must overcome certain challenges before their implementation to the industrial scale. These are: i) the utilization of the concentrated gas stream generated by the capture and gas purification technologies, ii) the reduction of the effects of impurities on the operating system, iii) the scale up of the relevant materials, and iv) the retrofitting of technologies in existing facilities. Thus, an innovative design of adsorbents could possibly address those issues. Biogas purification and CH storage would become a new motivation for the development of new sorbent materials, such as nanomaterials. This review discusses the current state of the art on the use of novel nanomaterials as adsorbents for CO and CH. The review shows that materials based on porous supports that are modified with amine or metals are currently providing the most promising results. The FeO-graphene and the MOF-117 based NPs show the greatest CO sorption capacities, due to their high thermal stability and high porosity. Conclusively, one of the main challenges would be to decrease the cost of capture and to scale-up the technologies to minimize large-scale power plant CO emissions.

“…Different classes of adsorbents were used for CH 4 storage such as carbons [14], zeolites [15][16][17][18], porous organic polymers [19,20], metal-organic frameworks (MOFs) [3,[21][22][23], and covalent organic frameworks (COFs) [24]. For each class of material, there has been an evolution in paradigm shifts for CH 4 design.…”

In this review, the evolution of paradigm shifts in CH4 adsorbent design are discussed. The criteria used as characteristic of paradigms are first reports, systematic findings, and reports of record CH4 storage or deliverable capacity. Various paradigms were used such as the systematic design of micropore affinity and pore size, functionalization, structure optimization, high throughput in silico screening, advanced material property design which includes flexibility, intrinsic heat management, mesoporosity and ultraporosity, and process condition optimization. Here, the literature is reviewed to elucidate how the approach to CH4 adsorbent design has progressed and provide strategies that could be implemented in the future.

“…To address the limitations associated with LNG and CNG processes, development of safe, efficient, and cost-effective NG storage alternatives has received considerable interest. In particular, the use of porous adsorbents as potential storage media for methane in the form of adsorbed natural gas (ANG) has been suggested as a safer, simpler, and more energy-efficient platform for the advancement of NG vehicular systems. ,− Several classes of materials have been investigated as potential ANG adsorbents including carbon-based materials, − MOFs, − covalent-organic frameworks (COFs), − and porous polymer networks (PPNs). − Because of their high surface area, pore volume, and tunable surface chemistry, MOFs have received considerable attention as promising candidates for methane storage. MOFs are able to store appreciable amounts of NG at moderately low pressures (less than 100 bar).…”

In this study, the storage of methane in nanocomposite adsorbents comprising metal−organic framework (MOF) and graphene oxide (GO) was investigated. Three different sets of MOF-GO nanocomposites comprising HKUST-1 and pristine GO, reduced GO (rGO), and carboxyl-functionalized GO (fGO) were developed by the solvothermal method, and their methane storage characteristics were assessed through high-pressure methane adsorption measurements. The formation of MOF-GO nanocomposites was confirmed by XRD, FTIR, XPS, SEM, and TEM. All three types of nanocomposites exhibited higher surface area and porosity than the pristine MOF. Our results indicated that MOF@rGO nanocomposite with 10 wt % rGO exhibited the best performance with a methane deliverable capacity of 193 cm 3 (STP)/cm 3 in the pressure range of 5.8−65 bar and at room temperature which was approximately 30% higher than that of pristine HKUST-1 with deliverable capacity of 149 cm 3 (STP)/cm 3 . Moreover, the methane deliverable capacity of MOF@GO and MOF@fGO were found to be 181 and 162 cm 3 (STP) /cm 3 , respectively. The findings of this study demonstrate the synergistic effect of graphene oxide on methane storage performance of MOF-GO nanocomposites.
