Nitrogen oxides (NOx) emissions carry pernicious consequences on air quality and human health, prompting an upsurge of interest in eliminating them from the atmosphere. The electrochemical NOx reduction reaction (NOxRR) is among promising techniques for removal potential conversion into valuable chemical feedstock with high efficiency while benefiting energy conservation. However, developing efficient stable electrocatalysts NOxRR remains arduous challenge. This review provides a comprehensive survey recent advancements NOxRR, encompassing underlying fundamentals mechanism rationale behind design using computational modeling experimental efforts. utilization Zn-NOx battery also explored as proof concept concurrent abatement, NH3 synthesis, decarbonizing generation. Despite significant strides this domain, several hurdles still need to be resolved long-lasting reduction. These possible means are necessary augment catalytic activity electrocatalyst selectivity surmount challenges catalyst deactivation corrosion. Furthermore, sustained research development could offer solution urgent issue pollution, culminating cleaner healthier environment.

Ammonia has gained more interest as a promising candidate to produce clean and renewable hydrogen energy in recent years. It is crucial develop new efficient method for improving the performance of NH3 synthesis. Nowadays, electrochemical synthesis by direct NO reduction become an alternative Haber–Bosch process. Herein, reaction (NORR) on 33 different H-functionalized MXenes (H-MXenes) been investigated combination density functional theory (DFT) calculations with least absolute shrinkage selection operator (LASSO) regression. Through surface Pourbaix diagrams Gibbs free-energy calculations, mechanism limiting potential (UL) NORR H-MXenes are investigated. The DFT demonstrate that H could regulate strength adsorption, lower free elemental step, effectively reduce potential, hence improve performance. Furthermore, results LASSO regression indicate good fitting between expression consisting combined descriptors from 1D 4D UL values calculations. Moreover, |Gv−ENO|2|GNO| regarded human-readable R2 = 0.83. This work not only provides deep insight into important role H-functionalization but also profits understand originals activity high-throughput screening catalysts.
