Metal–Organic‐Framework‐based Gas Chromatographic Separation

Abstract

Metal-organic frameworks (MOFs)h ave been applied in various fields because of their fascinating structures and excellent properties. MOFs can serve as stationary phases in gas chromatography (GC), which has led to exceptional improvements of performance. Here, we summarize the application of MOFs in GC based on the classification of analytes. The advantages and separation mechanism of MOFs as stationaryp hases in GC are discussed in combination with the characteristics and structures of MOFs. The limitationsa re also summarized in this review,w hich can provide prospects on furtherr esearch for the applications of MOFs.

Organic template-assisted green synthesis of CoMoO4 nanomaterials for the investigation of energy storage properties

“…However, the specic capacitance calculated for CoMoO 4 in the current study (even at the highest rate of 300 mV s À1 ) is much higher than the capacitance of 36 F g À1 of the MoO 3 nanorods, 66,67 12 F g À1 of Co 3 O 4 , 47 77 F g À1 of the commercial Co 3 O 4 electrode, 18 and 60 F g À1 of the Co electrode 8 at the lowest scan rate of 5 mV s À1 . Moreover, Table 2 depicts a comparison of the capacitance of the CoMoO 4 electrode with previously reported electrodes.…”

“…56 The phytofabricated CoMoO 4 exhibited an enhanced energy storage potential in comparison with several reported devices. 39,40,49,56,[65][66][67][68][69][70] On the other hand, the maximum recorded power density of CoMoO 4 was 7272.5 W kg À1 (7.3 kW kg À1 ), which is much higher than the power densities of MoO 3 , 66,70 Co 3 O 4 nanorods, 57 CoO/Co 3 O 4 , 49 CoO nanobers 56 and Co 3 O 4 @Carbon, 56 respectively. The Ragone plot (Fig.…”

Effect of NiO on organic framework functionalized ZnO nanoparticles for energy storage application

“…However, at the highest power density of 19 216.7, energy density of 2.13 was achievable, which is still higher than energy density of ZnO‐activated carbon, and NiO . The phyto‐fabricated ZnO@NiO exhibited enhanced energy storage potential than several reported devices . The Ragone plot (Figure C) depicts that when power density increased, the energy density was decreased and vice versa.…”

Facile ZnO-based nanomaterial and its fabrication as a supercapacitor electrode: synthesis, characterization and electrochemical studies

“…This is again credited to the fast Faradaic reactions of PdO/Pd. [55][56][57][58][59][60][61][62][63][64][65][66][67] ED of PFbinded ZnO@PdO/Pd was also improved than ZnO-activated carbon 39 ZnO NPs. 40 Excellent PD of ZnO@PdO/Pd was 3718 W kg À1 (3.7 KW kg À1 ) (Fig.…”
