“…After reduction, the peak at 2Ɵ = 11.9° reduces significantly and new hump appears between 2Ɵ = 20° to 30° which is due to the exfoliation of graphene sheets, which confirms the successful reduction of GO [11]. The XRD pattern of Cu-BTC shows the strong diffraction peaks at the 2Ɵ angles 6.7°, 9.5°, 11.6°, 14.7°, 15°, 16.5°, 17.5°, 19°, 20.2°, 21.3°, 23.4°, 24.1°, 26°, 27.7°, 28.7°, and 35.7° represent the (200), ( 220), ( 222), ( 331), ( 420), ( 422), ( 333), ( 440), ( 442), ( 620), ( 444), ( 551), ( 553), ( 733), (660), and (951) dhkl planes [10].…”

“…Furthermore, Figure j displays the Raman spectra of RGO, MOF(Ni), and MOF(Ni)@RGO- x . The peak at 862 cm –1 in MOF(Ni) corresponds to the C–H stretching mode, and the peaks at 1349 and 1612 cm –1 are attributed to the in-plane vibrational modes of the C–O bond and benzene ring, respectively. , Additionally, the peaks at 1133.5 and 1416.5 cm –1 correspond to COO– vibrational modes . The prepared RGO and MOF(Ni)@RGO- x have sp 3 disordered carbon (D band) and sp 2 hybridized graphitic layers (G band) .…”

Currently, the primary bottlenecks that hinder the widespread application of supercapacitors are low energy density and narrow potential windows. Herein, the hybrid supercapacitor with high energy density and wide potential window is constructed via an in situ self-assembly method employing RGO-induced flower-like MOF(Ni). Benefiting from the synergistic effect between RGO and MOF(Ni), the interfacial interactions are effectively improved, and the contact area with the electrolyte is enhanced, which increases the ion transfer kinetics and overall electrochemical performance. The MOF(Ni)@RGO electrode exhibits a specific capacitance of 1267.73 F g −1 at a current density of 1 A g −1 . Crucially, the assembled MOF(Ni)@RGO// BC with a broad potential window and good stability employing a MOF(Ni)@RGO anode and biomass carbon cathode, combined with a 2 M PVA-KOH gel-electrolyte, achieves a maximum energy density of 70.16 Wh kg −1 at a power density of 2200.09 W kg −1 , outperforming most reported supercapacitors. This hybrid supercapacitor exhibits excellent stability and high energy density, providing a novel strategy for further large-scale applications.

“…The authors suggested that the performance was due to the in situ production of atomic, ionic, and radical oxygen sites, which play a relevant role in both the adsorption of CO and electronic density rearmament. Furthermore, GRMs can be functionalized with polymers, as reported by Farea and co-workers [59,60] and by Mohammed et al [61], or by metal organic frameworks boosting the overall CO sensing performance, as reported by More et al [62].…”
