“…The mineralization of TCs was also evaluated in light of the TOC measurements (Table 2), the results of which confirm even more strongly what was previously concluded: that Co-CoNi at a pH of 8.0 activated PMS the best and consequently demonstrated the greatest degradation. Even so, it is important to highlight the strong performance of all of the catalysts, for after 1 h, the mineralization achieved by Ni-CoNi and Co-CoNi ranged between 85% and 94% for deposits treated 2 h at 225 • C and between 96% and 99.9% for deposits annealed 2 h at 350 • C The Co-CoNi (350 • C) deposits exhibited excellent catalytic activity, equal or even superior to state-of-the-art catalysts used to degrade and mineralize TCs via PMS catalysis, including petal-like hierarchical Co 3 O 4 -or N-doped porous carbon [42], partly carbonized Fe 3 O 4 @PANI-p [43], N-C codoped Fe 2 O 3 [44], Co/N codoped biochar [45], goethite-MoS 2 hybrid [46], porous CuFe 2 O 4 [47], and biochar supported-Co 3 O 4 [48], among others.…”

Synthesizing efficient heterogeneous catalysts with multiple active sites able to activate peroxymonosulfate (PMS) for the degradation of persistent organic pollutants continues to be a challenge for societies worldwide. In response, cost-effective, eco-friendly oxidized Ni-rich and Co-rich CoNi micro-nanostructured films were fabricated following a two-step process based on simple electrodeposition using green deep eutectic solvent as an electrochemical media and thermal annealing. The CoNi-based catalysts demonstrated exceptional efficiency in the heterogeneous catalyzed activation of PMS for tetracycline degradation and mineralization. The effects of the catalysts’ chemical nature and morphology, the pH, the concentration of PMS, irradiation with visible light, and the duration of contact with the catalysts on the degradation and mineralization of tetracycline were also studied. In dark conditions, oxidized Co-rich CoNi degraded more than 99% of tetracyclines in only 30 min and mineralized more than 99% of them in only 60 min. Moreover, the degradation kinetics doubled from 0.173 min−1 in dark conditions to 0.388 min−1 under visible light irradiation. In addition, the material demonstrated excellent reusability and can be easily recovered with simple heat treatment. Given those findings, our work provides new strategies for constructing high-efficiency and cost-effective PMS catalysts and elucidating the effects of operational parameters and primary reactive species formed by the catalyst–PMS system on water treatment technologies.

“…In contrast, doping-enabled construction of oxygen vacancies has been demonstrated to be a simple and effective approach to boost the catalytic activity of transition metal oxides. Wang et al synthesized an oxygen-deficient vacancy N–C-codoped Fe 2 O 3 catalyst with outstanding photoelectrocatalytic performance . Also, the efficacy of heteroatom doping, specifically with F, Br, and P, has been demonstrated. − In addition, the electron-deficient boron (B) dopant can rearrange the coordination structure of TMOs by a partial charge due to its slightly lower electronegativity than that of O and even alter its electron density.…”

High specific capacity and long cycle life are the key to high-performance lithium−sulfur (Li−S) batteries, but they are hard to achieve simultaneously due to the notorious polysulfide shuttle effect. Transition metal oxide nanocatalysts are expected to help address the above issue, but their low conductivity and cumbersome synthesis process limit their application. Here, we propose a defect engineering strategy to induce electron rearrangement by heteroatom doping. Boron-doped spinel-type oxide (B-ZnCo 2 O 4-x ) is synthesized by a two-step hydrothermal method for separator modification. The boron-produced oxygen vacancy (O V ) increases unsaturated sites by changing the electron cloud density, and therefore, the B-ZnCo 2 O 4-x nanocatalyst can reduce the reaction energy barrier and accelerate the nucleation and activation rate of Li 2 S. Meanwhile, the unique pore defects effectively increase the Li + flux and ensure battery performance at a high rate and high sulfur loading. The battery equipped with a B-ZnCo 2 O 4-x -modified separator delivered an initial specific capacity of 1108 mAh g −1 at 0.2 C and a capacity retention rate of 80.4% at 0.5 C after 200 cycles. In particular, at a high sulfur loading of 10.0 mg cm −2 , the battery yielded a first-cycle capacity of 1321.9 mAh g −1 . This work demonstrates that boron-doping-enabled defect engineering is an effective strategy to improve the catalytic activity of transition metal oxides for application in Li−S batteries.
