Combine and conquer Platinum (Pt)–group metals, which are scarce expensive, used for the demanding oxygen reduction reaction (ORR) in hydrogen fuel cells. One competing approach reducing their use is to create nanoparticles with earth-abundant metals increase activity surface area; another replace them such as cobalt (Co) carbide or nitride sites. Chong et al. thermally activated a Co metal-organic framework compound ORR-active sites then grew PtCo alloy on this substrate. The resulting...
In this work, we report the remarkable catalytic effects of a novel Ti3C2 MXene-based catalyst (Ni@Ti-MX), which was prepared via self-assembling Ni nanoparticles onto surface exfoliated nanosheets. The resultant Ni@Ti-MX catalyst, characterized by ultradispersed being anchored on monolayer flakes, introduced into MgH2 through ball milling. situ transmission electron microscopy (TEM) analysis revealed that synergetic effect multiphase components (Mg2Ni, TiO2, metallic Ti, etc.) derived in +...
MXenes are considered as potential support materials for nanoconfinement of MgH2/Mg to improve the hydrogen storage properties. However, it has never been realized so far due stacking and oxidation problems caused by unexpected surface terminations (-OH, -O, etc.) on MXenes. In this study, hexadecyl trimethylammonium bromide was used build a 3D Ti3C2Tx architecture folded nanosheets reduce risk flakes, bottom-up self-assembly strategy successfully applied synthesize ultradispersed MgH2...
Abstract MgH 2 has attracted intensive interests as one of the most promising hydrogen storage materials. Nevertheless, high desorption temperature, sluggish kinetics, and rapid capacity decay hamper its commercial application. Herein, 2D TiO nanosheets with abundant oxygen vacancies are used to fabricate a flower-like /TiO heterostructure enhanced performances. Particularly, onset temperature is lowered down 180 °C (295 for blank ). The initial rate reaches 2.116 wt% min −1 at 300 °C, 35...

Abstract Rechargeable aqueous zinc batteries are potential candidates for sustainable energy storage systems at a grid scale, owing to their high safety and low cost. However, the existing cathode chemistries exhibit restricted density, which hinders extensive applications. Here, tellurium redox‐amphoteric conversion chemistry is presented batteries, delivers specific capacity of 1223.9 mAh g Te −1 density 1028.0 Wh kg . A highly concentrated electrolyte (30 mol ZnCl 2 ) revealed crucial...
Abstract Metal‐organic frameworks (MOFs) have exhibited encouraging catalytic activity for the oxygen evolution reaction (OER), a crucial process water electrolysis to produce green hydrogen. Nonetheless, distinguishing source of and establishing structure‐composition‐property relationships MOFs during OER processes remain challenging. Here, first time, operando X‐ray absorption spectroscopy (XAS) is utilized monitor structural identify active components ferrocene‐based (Ni‐Fc) OER....
Hydrogen holds the advantages of high energy density, great natural abundance and zero emission, making it suitable for large scale long term storage, while its safe efficient storage is still challenging. Among various solid state hydrogen materials, MgH2 promising industrial applications due to gravimetric volumetric densities Mg on earth. However, practical application has been limited by stable thermodynamics slow desorption kinetics. Nanocatalysis considered as a approach improving...
Reducing Mg particles to nanoscale and doping with various catalysts are considered as efficient approaches for improving the hydrogen storage properties of Mg/MgH2. It has been established that Ni or Mg2Ni into nano-Mg/MgH2 through physical routes remarkably improves sorption kinetics. In this work, a Mg–Ni nanocomposite coprecipitated from tetrahydrofuran (THF) solution containing anhydrous magnesium chloride (MgCl2), nickel (NiCl2), lithium naphthalide (LiNp) reducing agent.
