“…[67] It is attributed to the increased density of electron occupancy states near the Fermi level, thereby enhancing charge transfer ability and electronic conductivity for Mo/Fe/Co@NC. [68] This observation is consistent with the findings from the Bader charge analysis (Figure 5c) and the charge difference density analysis (Figure 5d).…”

Recently, zeolitic imidazolate frameworks (ZIFs) composites have emerged as promising precursors for synthesizing hollow‐structured N‐doped carbon‐based noble‐metal materials with diverse structures and compositions. Here, a strong/weak competitive coordination strategy is presented for synthesizing high‐performance electrocatalysts with hollow features. During the competitive coordination process, the cubic zeolitic‐imidazole framework‐8 (Cube‐8)@ZIF‐67 with core–shell structures are transformed into Cube‐8@ZIF‐67@PF/POM with yolk–shell nanostructures employing phosphomolybdic acid (POM) and potassium ferricyanide (PF) as the strong chelator and the weak chelator, respectively. After calcination, the hollow Mo/Fe/Co@NC catalyst exhibits superior performance in both oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). Interestingly, the Mo/Fe/Co@NC catalyst exhibits efficient electrocatalytic performance for Zn–air batteries (ZABs), with a high power density (≈150 mW cm−2) and superior cycling life (≈500 h) compared to commercial platinum/carbon (Pt/C) and ruthenium dioxide (RuO2) mixture benchmarks catalysts. In addition, the density functional theory further proves that after the introduction of Mo and Fe atoms, the adsorption energy with the adsorption intermediates is weakened by adjusting the d‐band center, thus weakening the reaction barrier and promoting the reaction kinetics of OER. Undoubtedly, this study presents novel insights into the fabrication of ZIFs‐derived hollow structure bifunctional oxygen electrocatalysts for clean‐energy diverse applications.

“…A more negative adsorption energy implies stronger material adsorption for HCHO. 40,41 It was found that the E ads values of materials are negative except for Mn-C 2 N and Mn 2 -C 2 N, indicating that for these materials the adsorption of HCHO is a thermodynamically spontaneous reaction. Note that for transition metals of the same period, the metals of IIIB and IVB groups anchored on C 2 N are more strongly adsorbed to HCHO.…”

Currently, in the era of highly advanced information technology, dielectric materials exhibit extensive potential applications in the realms of energy storage and information transmission. Polypropylene stands as one of the most prevalent plastics, lauded for its exceptional mechanical, thermal, electrical, and processing attributes. This article expounds upon the intricate essence and energy storage principles underpinning dielectric materials while pinpointing the areas in which the current dielectric materials necessitate enhancements. It further delves into the study's selection of polypropylene as the base material, with a focus on the impact of individual fillers (ferroelectric ceramics, carbon materials, etc.) and mixed filler nanoparticles on augmenting the dielectric properties of polypropylene. We also delve into pertinent fabrication techniques and methodologies, such as the solution blending method, melt blending method, and in situ polymerization method. In the context of existing polypropylene‐based composite dielectric materials, this article introduces two quintessential applications: insulation materials for direct current cables and metal capacitor films. Finally, it concludes by summarizing the obstacles and challenges that high‐performance polypropylene‐based dielectric composites confront and offers insights into potential avenues for future research.
