“…Despite the interference of various organic pollutants, it can be seen in the above figure that with the prolongation of the reaction time, the SMX degradation efficiency of MOF-525-Fe/Zr-modified cathode continued to increase, and after 180 min, the TOC removal rates of the three water samples were more than 75%. Moreover, MOF-525-Fe/Zr-modified cathode significantly improves the mineralization rate of SMX compared with MOF-like catalysts proposed in previous studies (Table 3) [66][67][68][69][70][71][72][73][74].

Photoelectro-Fenton (PEF) process can continuously promote the occurrence of Fenton reaction and the generation of active species, which is an advanced oxidation technology for pollutant degradation. However, the lack of bifunctional catalysts restricts the development of PEF technology. In this study, the electronic rearrangement MOF-525 modified by metalloporphyrin (named MOF-525-Fe/Zr) was prepared, to load on the carbon felt as a novel cathode catalyst, which is used in PEF process. A series of characterization and photoelectric chemical properties tests combined with DFT calculation showed that the modification of MOF-525 could not only have the large specific surface area and multistage pore structure but also co-stimulate the metal-to-ligand charge transfer (MLCT) and ligand-to-cluster charge transfer (LCCT) by photoelectric synergy. These charge transitions provide periodic electron donor-acceptor conduction paths in MOF-525-Fe/Zr, which can improve the active species formation and transfer efficiency. Owing to their favorable pore and electronic structure as well as stability, MOF-525-Fe/Zr shows great promise for the application in the catalytic process of PEF. Sulfamethoxazole (SMX) degradation was enhanced by MOF-525-Fe/Zr with the TOC removal rate above 75% both in river water and tap water. Finally, the reasonable pathway of PEF catalytic degradation of SMX was proposed by HPLC-MS analysis. In conclusion, this study provides a new idea for reconstructing the electronic structure of MOFs catalyst and broadening the practical application of PEF technology.

Metal−organic frameworks (MOF) are versatile and good structurally stable materials that are widely used in energy conversion and storage. In this work, rare-earth-based bimetallic metal−organic framework (NiY-BTC) nanorods anchored with transition metal−organic frameworks (ZIF-67) were used as versatile precursors to prepare novel metal/rare-earth metal oxidecoupled carbon-based bifunctional oxygen electrocatalysts (NiY/C@Co/C). Due to the stable nanorods framework structure, appropriate Y 2 O 3 active center, and richness of Co−N sites in the carbon skeletons, the NiY/C@Co/C catalyst exhibits high onset potentials (E onset = 0.928 V) and half-wave potential (E 1/2 = 0.83 V) for the oxygen reduction reaction (ORR), and expresses a low overpotential (η = 392 mV@10 mA cm −2 ) for the oxygen evolution reaction (OER). Moreover, a rechargeable Zn−air battery assembled with NiY/C@Co/C as the air cathode catalyst displayed a great specific capacity (899.6 mAh gZn −1 ) and a remarkable peak power density of 102.2 mW cm −2 , as well as excellent durability and stability. This work delivers a way using rare-earth metal− organic frameworks to get the corresponding metal oxide-coupled carbon-based bifunctional oxygen electrocatalysts for rechargeable Zn−air batteries.

“…However, it is difficult to obtain satisfactory ORR performance from some of the inexpensive ORR catalysts developed in recent years (metal oxides , and heteroatomic doped carbon materials , ). Recent studies have shown that modification of nitrogen-doped carbon with some non-noble transition metal species (M–N–C) can increase its catalytic electrochemical activity toward ORR to the point Pt-based catalysts have reached, − due to its unique distribution of active sites and controllable composition of components. Metal–organic frameworks (MOFs) are widely regarded as the applicable precursors for preparing M–N–C catalysts on account of their surprisingly huge and controlled specific surface area, abundant and regulable pore structure, adjustable composition, and intrinsic heteroatomic doping .…”

The sluggish and inefficient oxygen reduction reaction (ORR) of cathode catalysts in microbial fuel cells is widely accepted as the key restriction in implementing their large-scale actual production application. Recently, modification of nitrogen-doping carbon materials with some transition metal species (M–N–C) is expected to be reserve force to substitute commercial noble metal catalysts. However, long-term stability is always unable to solve effectively. We report a simple synthetic approach of metal–organic framework-derived hollow core–shell Co–nitrogen codoping-modified porous carbon catalysts (N–C@Co/N–C–n%Ni), which is introduced by bits of Ni substance, via the template method and vacuum-assisted impregnation method that exhibit similar catalytic activity to commercial Pt/C catalysts. The hollow core–shell H–N–C@Co/N–C–3%Ni catalyst shows excellent ORR performance and stability, which is 96.31% of the initial current after 125 h continuous reaction, and has been capable of yielding a maximum power density of 1.17 ± 0.01 W·m–2 with 2% decrease in 45 days for long-term continuous operation.
