Abstract This work reports boron and oxygen dual‐doped carbon nitride nanotubes (B/O‐CNNTs) prepared via a copolymerization process for electrocatalytic ammonia synthesis from nitrogen gas (NRR) nitrate (NO 3 RR) sources, respectively. By adjusting the dosage of oxide precursor, texture content B/O dual dopants coordination environment in resulting 1D CNNTs can be tuned. The best B/O‐CNNTs achieve maximum Faradaic efficiencies 35% 96% at −1.1 V versus RHE with corresponding yields 16.7 211.4 µg h −1 mg , A comparatively higher selectivity is achieved NRR compared to NO RR. B/O‐induced coordinations boost electron transfer rates along longitudinal axis. presence vacancies unique nanotubular structure enhance interactions among reactants. Concurrently, formed frustrated Lewis pairs are pivotal activating chemisorbed or nitrate, notable accelerations generation kinetics. In situ UV–vis spectroscopy reveals that ideal potential facilitates involvement free electrons reaction, as it aligns conduction B/O‐CNNTs. study paves way design non‐metal‐based electrocatalysts sustainable electrocatalysis toward synthesis.

Abstract The electrocatalytic nitrate reduction reaction (NO 3 RR) presents a promising alternative to the traditional Haber‐Bosch process for synthesizing ammonium (NH ) under mild conditions. Supported single atoms have emerged as active catalysts this conversion; however, efficiency of NH production are limited by modest activity and selectivity these catalysts. In study, it is demonstrated that zinc supported on nitrogen‐doped carbon (ZnNCs), derived from zeolitic imidazolate framework‐8 (ZIF‐8), possess remarkable catalytic performance conversion, achieving an unprecedented (exceeding 90%) formation across broad potential range (−0.4–−0.8 V vs. RHE). Comprehensive analyses reveal incorporation graphitic nitrogen atom adjacent Zn‐N 4 site precisely modulates pathway, enabling unique dual‐site adsorption cascading route formation. These findings not only uncover novel mechanism NO RR but also inspire development more efficient
