“…As shown in Figure 2D , the main peaks at 932.47 and 952.58 eV in the Cu 2p spectrum are assigned to Cu 2p 3/2 and Cu 2p 1/2 spin-orbit states, respectively, which indicates the Cu 2+ state in the Cu-MOF ( He et al, 2016 ). The satellite peaks of Cu 2+ can also be observed at 939.51, 943.84, and 962.24 eV ( Liu et al, 2013 ; Tian et al, 2017 ).…”

“…The full spectrum of XPS reveals the existence of C, O, and Cu elements in Cu-MOF, which corresponds with EDX ( Figure 2A ). The XPS peaks of C 1s can be observed at 283.98, and 287.72 eV ( Figure 2B ), which are composed of C–O and C–C, respectively ( Jin et al, 2006 ; Yan et al, 2010 ; Tian et al, 2017 ). In the O 1s spectrum ( Figure 2C ), there are two O species, namely, O–Cu at 530.42 eV and O–H at 532.48 eV ( Yang et al, 2020 ).…”

A non-enzymatic electrochemical sensor for glucose detection is executed by using a conductive metal–organic framework (MOF) Cu-MOF, which is built from the 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) ligand and copper acetate by hydrothermal reaction. The Cu-MOF demonstrates superior electrocatalytic activity for glucose oxidation under alkaline pH conditions. As an excellent non-enzymatic sensor, the Cu-MOF grown on Cu foam (Cu-MOF/CF) displays an ultra-low detection limit of 0.076 μM through a wide concentration range (0.001–0.95 mM) and a strong sensitivity of 30,030 mA μM−1 cm−2. Overall, the Cu-MOF/CF exhibits a low detection limit, high selectivity, excellent stability, fast response time, and good practical application feasibility for glucose detection and can promote the development of MOF materials in the field of electrochemical sensors.

“…The efficiency of cathode is dependent on the following factors: i) electron acceptor used ii) proton availability iii) catalyst used iv) catalytic ability of electrode, dissolved oxygen level ,. A highly porous cathode materials can generate high power density than the planar ones by the presence of large surface area for reaction and also suitable for bacterial growth in biocathodes . The rough surface cathodes also generate more power density as compared to the flat ones .…”

Though various cost‐effective catalysts like MnO 2 , MoS 2 , NiO/CNTs, activated carbon, metal‐organic framework, Co 3 O 4 nanorods have been developed as an alternative to Pt, they couldn't achieve the performance of Pt ,, . Thus motivating the researcher to address the vacuum of the objective.…”

Microbial fuel cell technology that works on the principle of resource recovery has gained wide popularity among the scientific world. These MFCs were seen as a solution provider for the present day's energy crisis through a non-traditional sustainable way. Although immense research has marked the development of this system since its innovation, the technol-ogy has not competed the commercial implication owing to various associated materialistic and operating limitations. The perspective provides an overview of the various limitations faced that constraints its real-time application along with perspective solutions.

“…More specifically, the ORR supported by MOF-based catalysts showed a four-electron reduction pathway, which is the most favorable for application in MFCs. For example, Cu 3 (BTC) 2 showed a four-electron reduction pathway for the ORR, and the MFC could achieve a power density of 1772 ± 15 mW/m 2 upon using it as the cathode catalyst. Similarly, g-C 3 N 4 -assisted MOF and MOF-derived Co 3 O 4 /NiCo 2 O 4 also exhibited a four-electron reduction pathway with excellent power harvesting efficiencies (1402.8 and 45250 mW/m 3 , respectively). , Additionally, cobalt/nitrogen-co-doped nanoscale Zr-metal-based MOFs and Cu-MOFs also exhibited a four-electron reduction pathway with a promising power recovery (95.8 and 81.1% for Pt/C cathode catalyst-based MFC, respectively).…”

Porous catalysts with a higher activated surface area are strategic materials to enhance the oxygen reduction reaction (ORR) and improve the performance of the microbial fuel cells (MFCs). In this investigation, a highly porous cagelike zirconium metal−organic framework (Zr-MOF) was synthesized by the solvothermal method and used as the ORR catalyst in an air-cathode MFC. Raman spectroscopy, X-ray diffraction, scanning electron microscopy, and energydispersive X-ray spectroscopy revealed the successful synthesis of Zr-MOF having a high specific surface area of 858 m 2 /g. Cyclic voltammetry analysis demonstrated a sharp ORR peak current at −0.38 V having a current value of 11 mA compared to the negligible amount of peak current observed for cathode having no catalyst. The MFC having Zr-MOF-catalyzed cathode could translate a power density of 131.2 ± 3.5 mW/m 2 at a coulombic efficiency of 29.04 ± 1.54% from the organic matter present in wastewater; these values were comparable with the MFC having 10% Pt/C on cathode (128.7 ± 4.9 mW/m 2 and 29.03 ± 2.76%, respectively). The cost of energy production by the Zr-MOF cathode was estimated to be ca. 4.4 times lower than that by the 10% Pt/C cathode. The performance of MFC indicates that Zr-MOF could be an excellent alternative cathode catalyst, to the costly Pt/C, upon ambitious scale-up of MFCs.
