Article Abstract
A benzoquinone derivative annelated by two imidazole rings was investigated as an organic anolyte of aqueous redox flow batteries. The anolyte showed a high solubility of 0.18 M in 1 M KOH aqueous solution and exhibited a one-step two-electron reversible redox wave with a half-wave potential of -0.59 V SHE. An aqueous redox flow cell comprising the benzoquinone-imidazole hybrid as the anolyte and potassium ferrocyanide as the catholyte showed an operating voltage of ∼1.1 V and minimum capacity fading of over 220 cycles.

High capacity, selective recovery and separation of precious metals from complex aqueous solutions is essential but remains a challenge in practical applications. Here, we prepared a thiophene-modified aromatic porous organic cage (T-PAC) with high stability for precise recognition and recovery of gold. T-PAC exhibits an outstanding gold uptake capacity of up to 2260 mg/g with fast adsorption kinetics and high adsorption selectivity.

Aqueous zinc-iodine batteries (AZIBs) are gaining attention as next-generation energy storage systems due to their high theoretical capacity, enhanced safety, and cost-effectiveness. However, their practical application is hindered by challenges such as slow reaction kinetics and the persistent polyiodide shuttle effect. To address these limitations, we developed a novel class of covalent organic frameworks (COFs) featuring electron-rich nitrogen sites with varied density and distribution (N1-N4) along the pore walls.

Ampicillin (AMP) ranks third among the top ten most frequently sold antibiotic combinations globally, raising concerns due to its extensive use. Improper disposal practices in agriculture, aquaculture, and healthcare have led to environmental contamination of water sources with elevated AMP levels. Current methods for detecting such contamination are costly, require sophisticated equipment, and depend on skilled personnel and unstable natural receptors.

To boost supercapacitor (SC) energy density, we introduced redox-active molecules into an aqueous HSO electrolyte. Using retrosynthetic analysis, we identified aminoquinones, specifically triaminochlorobenzoquinone (TACBQ), as promising candidates. Characterization via elemental analysis, Fourier Transform Infrared Spectrometer (FT-IR), nuclear magnetic resonance (NMR), and X-ray photoelectron spectroscopy (XPS) confirmed structure of TACBQ.
