Support Regulation Strategy Synergistic with Ru Single-Atom Catalyst for Energy-Saving Hydrogen Production Assisted by Green Electrosynthesis of Azotetrazolate.

The slow kinetics of the oxygen evolution reaction limits electrochemical overall water splitting (OWS). To address this, integrating thermodynamically favorable organic electro-oxidation with the hydrogen evolution reaction (HER) can enhance the hydrogen production performance. Notably, 5-amino-1-tetrazole oxidation-assisted OWS not only achieves energy-saving hydrogen production but also produces energetic compound 5,5'-azotetrazolate salts in a mild manner.

Electro-Triggered Cascade Cyclization to Access Phosphinyl-Substituted -Containing Heterocycles.

An electro-triggered cascade cyclization strategy was disclosed with concomitant phosphinylation and -heterocycle construction. It provides a novel and environmentally friendly approach to access phosphinyl-substituted -heterocycles with no external metal catalyst, oxidant, or heating. Mechanistic studies have revealed that anodic oxidation of H-phosphorus compounds occurs first to generate the key P-centered radical directly and cathodic reduction leads to the concurrent release of molecular hydrogen or methane.
