Bimetallic oxide Cu₂O@MnO₂ with exposed phase interfaces for dual-effect purification of indoor formaldehyde and pathogenic bacteria.

ABSTRACT: The combination of materials with different functions is an optimal strategy for synchronously removing various indoor pollutants. For multiphase composites, exposing all components and their phase interfaces fully to the reaction atmosphere is a critical problem that needs to be solved urgently. Here, a bimetallic oxide Cu₂O@MnO₂ with exposed phase interfaces was prepared by a surfactant-assisted two-step electrochemical method, which shows a composite structure of non-continuously dispersed Cu₂O particles anchored on flower-like MnO₂. Compared with the pure catalyst MnO₂ and bacteriostatic agent Cu₂O, Cu₂O@MnO₂ respectively shows superior dynamic formaldehyde (HCHO) removal efficiency (97.2% with a we
