Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Mesoporous Polymer for Metal Ion Adsorption and Its Calcined Product for Oxygen Reduction Reaction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel emulsion‐assisted oxidative polymerization strategy is developed to synthesize mesoporous poly(diaminonaphthalene) (PDAN) with excellent Fe3+ adsorption performance, featuring uniform morphology and well‐defined mesopores. Pyrolysis of Fe‐adsorbed PDAN yields nitrogen‐doped mesoporous carbon embedded with Fe3C nanoparticles (NCs‐Fe), and the ...

Electron‐Rich Para‐Methylpyridine‐Functionalized TEMPO Empowers Long‐Lived Neutral Aqueous Organic Redox Flow Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Three methylpyridine‐functionalized TEMPOs were synthesized through an electron‐rich regulation strategy. The calculation of transition states supported the highest reaction efficiency of para‐MePy‐TEMPOs, which outperformed its analogues to have the best performance of AORFBs, opening a new avenue for exploring TEMPO‐based catholytes.

Synthesis, Structure, and Lewis Acidity of Heavy Pnictenium Cations

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of donor‐coordinated and donor‐free heavy pnictenium cations were synthesized and structurally characterized. The cations are strong Lewis acids according to experimental (Gutmann–Beckett method) and computational studies (FIAs). Strained pnictanes L1PnNaph (Pn = Sb 1, Bi 2; L1 = 2,6‐(2,4,6‐i‐Pr3C6H2)2C6H3) were synthesized and protonation ...

Redox Potentials for the Synthesis of Cationic Transition Metal Complexes from the Metal and Weak Ligands: A Computational Methodology for Practical Oxidant Choice

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Identifying synthetic targets: A computational methodology for the estimation of redox potentials of weakly coordinated transition metal complexes was established. Using Born–Fajans–Haber cycles, metal ionization and sublimation energies, solvation energies, and coordinative strength of the ligand were identified as potential‐determining parameters. In
