Hydrothermally driven three-dimensional evolution of mesoporous hierarchical europium oxide hydrangea microspheres for non-enzymatic sensors of hydrogen peroxide detection

Abstract

Hydrothermal synthesis of mesoporous europium oxide hierarchical hydrangea microspheres for electrochemical detection of hydrogen peroxide (H₂O₂) has been successfully achieved. The as-prepared stable enzyme-free sensor is capable of performing H₂O₂ detection in a broad linear range, with high sensitivity, a remarkably low detection limit and rapid response.
