“…The D band was connected with the defect level of carbon, and the G band was connected with the carbon sp 2 hybrid. 28 As shown in the Raman curve of Vulcan XC-72R, the peaks of the D and G bands were located at 1347 and 1593 cm −1 , respectively. The peaks of the D and G bands of MoO 2 /Mo 2 C/C showed a negative shift, which meant that the charge transfer process between the Vulcan XC-72R and MoO 2 /Mo 2 C improved the ORR catalytic properties.…”

The rational design of efficient, stable, low‐cost non‐precious metal‐based electrocatalysts with enhanced oxygen reduction reaction (ORR) activity has attracted widespread attention. In this study, a novel electrocatalyst, Fe/Co‐N‐MWCNT, was prepared by in‐situ growth of ZIF‐8 and Fe/Co‐Phen on multi‐walled carbon nanotubes (MWCNTs), then pyrolysis under different temperature to obtain optimal one. During the pyrolysis process, the incorporation of Fe and Co facilitated the formation of metal active sites and Fe‐Co alloy, thereby promoting electron transfer and enhancing the ORR activity. Compared to Pt/C (E1/2 = 0.854V, JL = 4.90 mA cm‐2), Fe/Co‐N‐MWCNT demonstrated a comparable half‐wave potential (E1/2 = 0.812V) and an enhanced limiting current density (JL = 5.37 mA cm‐2). Furthermore, Fe/Co‐N‐MWCNT was stable and showed no significant change after 2000 cycles, with only a negative shift of 7 mV in E1/2. Ampere response testing revealed that the current decay of Fe/Co‐N‐MWCNT after 10000 s was only about 7.8%, while that of Pt/C was about 18.4%. Due to its excellent catalytic stability, Fe/Co‐N‐MWCNT was demonstrated to be an excellent candidate for rechargeable zinc‐air batteries. The outstanding electrocatalytic performance of Fe/Co‐N‐MWCNT can be attributed to its high pyridinic nitrogen content, the unique structure and abundant metal active sites.

In this contribution, a new Schiff‐base hybrid cross‐linked polymer (TFPT‐SHCP) derived from triazine derivatives and silsesquioxanes was developed, and its photocatalytic performance was systematically investigated. Compared with traditional organic Schiff base catalysts, in TFPT‐SHCP, organic inorganic hybrid silsesquioxanes monomers at the molecular level can serve as a sturdy host backbone, bringing structural ultrastability to the final material. And their excellent strength and durability make them have good application prospects in water treatment. Furthermore, the introduction of triazine derivatives with excellent photoelectric performance and the construction of ‐C=N‐ result in excellent photocatalytic performance of TFPT‐SHCP. The as‐prepared TFPT‐SHCP exhibit excellent degradation capacity of various organic pollutants under visible light catalysis, with degradation rate constants for Congo Red (CR), rhodamine B (RB) and tetracycline hydrochloride (TH) reaching 0.302 min‐1, 0.121 min‐1, 0.161 min‐1, respectively. Under simulated outdoor conditions, dye solutions with concentrations up to 500 ppm can be degraded to complete decolorization within 5 weeks. This work demonstrates the enormous potential of POSS‐based Schiff base materials as a platform for visible light catalysts, paving the way for the pre design and functionalization of related materials in the future.
