Origins of NO 3 RR activity and selectivity on Cu 2 O-derived catalysts: interplay of oxidation states, surface reconstruction, and reaction conditi

Han Zhou, Neil Qiang Su

Cu 2 O reconstruction generates distinct active sites, dominated by pentagonal defect and square-step sites. NH 3 selectivity is primarily governed by active-site configuration, whereas NO 3 RR–HER competition is mainly controlled by potential and pH.
