Transforming the Poison Effects of Water Vapor into Benefits Over Adjustable Dual Acid Sites for Stable Plasma‐Catalysis

Advanced Science, EarlyView.
YxMnyOx+2y catalyst provides dual active sites of Lewis acid (Y3+) and Mn for the co‐adsorption of H2O and O3, and the fast dissociation of adsorbed H2O to surface *OH. Then, a newly OH‐accompanied pathway for O3 decomposition is formed, transforming H2O to active ·OH radical, with the assistance of high energy electrons in the plasma.

Two‐Step Tandem Catalysis for High‐Efficiency Ammonia Synthesis Via Nitrate Reduction on Anion‐Intercalated CoNi LDH and Cu/Cu2O

Advanced Science, EarlyView.
By integrating Cu/Cu2O and CoNi LDH, tandem kinetic descriptors, including a volcano curve, are employed to predict rate constants, facilitating ideal kinetic matching for efficient ammonia synthesis. The highest ammonia yield (1.12 mmol cm−2 h−1) and Faraday efficiency (99.78%) are achieved by rate matching between Cu/Cu2O and MoO4‐CoNi LDH.
