Constructing AgO/Ag2O Electrocatalysts with Highly Exposed and Tightly Contacted Active Facets for Efficient Oxygen Evolution.

The development of efficient electrocatalysts for the oxygen evolution reaction (OER) and the elucidation of their underlying mechanisms are crucial for overcoming the low efficiency of hydrogen production through the electrolysis of water. Utilizing the electrochemical anodic oxidation method, a series of silver-based electrocatalysts (Ag-x, where x signifies the applied direct current (DC) voltage, x = 0, 5, 10, 15) were prepared employing metallic silver wire as the anode under DC voltages. The resulting silver-based electrodes have been oxidized and reconstructed, yielding AgO/Ag2O composite on the surface.

Application of surfactant modified montmorillonite with different conformation for photo-treatment of perfluorooctanoic acid by hydrated electrons.

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are a class of highly persistent contaminants with high bioaccumulation and toxicity.
