Enhanced electrochemical activity by MOF superstructure derived NiP@C for ultrasensitive sensing of Bisphenol A.

Electrochemical (EC) sensing of bisphenol A (BPA), a notorious persistent contaminant, is of pressing interest. However, the state-of-the-art BPA sensors are challenged by two performance parameters: limited EC catalysis and sensitivity. Herein, a two-dimensional (2D) metal-organic framework (MOF) superstructure-derived NiP@C probe elicits a novel EC sensor that exhibits high-efficiency BPA detection.

Sustainable High-Performance Aqueous Batteries Enabled by Optimizing Electrolyte Composition.

Lithium-free aqueous batteries (LFABs) offer a sustainable alternative to lithium-ion batteries for large-scale energy storage, addressing issues like material scarcity and flammability. However, their economic viability is limited by low energy density and cycle life due to the narrow electrochemical stability window of water and active material dissolution. High-concentration water-in-salt electrolytes typically used to tackle these issues are expensive and potentially hazardous.
