Superconjugated Anthraquinone Carbonyl-Based Covalent Organic Framework as Anode Material for High-Performance Aqueous Ammonium-Ion Batteries.

Covalent organic frameworks (COFs) have recently been emerged as promising anode candidates for aqueous ammonium ion batteries (AAIBs), but suitable COFs need to be developed and the energy storage mechanisms need to be further investigated. Here we report an anthraquinone carbonyl-containing COF as anode for AAIBs, which exhibits a high specific capacity of 141 mAh g at 0.1 A g and good cycling stability with 90 % retention after 8000 cycles at 6 A g.

CoO/NiCoO heterojunction as oxygen evolution reaction catalyst for efficient luminol anode electrochemiluminescence.

Luminol has garnered significant attention from analysts as one of the most effective and commonly used electrochemiluminescence (ECL) reagents. However, the efficient luminescence of luminol anode is limited by the excitation of various reactive oxygen species (ROS). Typically, ROS are generated through co-reactive reagents and dissolved oxygen.
