Abstract The electrochemical nitrate reduction reaction (NO 3 RR) holds promise for ecofriendly removal. However, the challenge of achieving high selectivity and efficiency in electrocatalyst systems still significantly hampers mechanism understanding large‐scale application. Tandem catalysts, comprising multiple catalytic components working synergistically, offer promising potential improving NO RR. This review highlights recent progress designing tandem catalysts RR, including noble metal‐related system, transition metal electrocatalysts, pulsed electrocatalysis strategies. Specifically, optimization active sites, interface engineering, synergistic effects between catalyst components, various situ technologies, theory simulations are discussed detail. Challenges opportunities development scaling up RR further discussed, such as stability, durability, mechanisms. By outlining possible solutions future design, this aims to open avenues efficient comprehensive insights into mechanisms energy sustainability environmental safety.

Electrochemical conversion of nitrate offers an efficient approach to mitigate pollution and ammonia synthesis but is still challenged by the slow kinetics selectivity issues active sites. Herein, performing density functional theory (DFT) calculations, we report a double-atom catalyst PdCu–C7N6 incorporating Pd Cu together embedded in C7N6 frameworks, which not only shows outstanding catalytic performance with low limiting potential 0.36 V, also can effectively inhibit competing hydrogen evolution reactions. The high NO3RR activity on well explained polarizable bond length as asymmetric charge distribution Pd–Cu dual This DFT work opens avenue for developing highly multicomponent electrocatalysts.

Fuel cells/zinc–air cells represent a transformative technology for clean energy conversion, offering substantial environmental benefits and exceptional theoretical efficiency. However, the high cost limited durability of platinum-based catalysts sluggish oxygen reduction reaction (ORR) at cathode severely restrict their scalability practical application. To address these critical challenges, this study explores groundbreaking approach to developing ORR with enhanced performance reduced costs. We present novel Pd3Cu alloy, innovatively modified N-doped carbon aerogels, synthesized via simple self-assembly freeze-drying method. The three-dimensional aerogel-based porous structures provide diffusion channels molecules, excellent electrical conductivity, abundant sites. Pd3Cu@2NC-20% aerogel exhibits remarkable enhancement in activity, achieving half-wave potential 0.925 V, limiting current density 6.12 mA/cm2, long-term stability. Density functional theory (DFT) calculations reveal that electrons tend transfer from Pd atoms neighboring *O, leading an increase negative charge around *O. This, turn, weakens interaction between catalyst surface *O optimizes elementary steps process.
