Boosted H2O2 activation to dissociated hydroxyl radical by regulating B sites in copper-based delafossite for contaminants degradation: Key role on adsorption configuration and occurrence forms

Key Points

• Hydroxyl radical generation is significantly increased with boosted H2O2 activation and optimized adsorption configuration.
• Key evidence shows up to 50% improvement in contaminants degradation efficiency using the modified copper-based delafossite.
• Analysis of catalytic performance across various configurations highlights the role of B sites in hydroxyl radical production.
• These findings suggest potential for developing more effective environmental detoxification methods using modified materials.
