“…For the precise engineering of electrocatalysts in enhancing their activity and selectivity, heteroatom incorporation into existing catalysts emerges as a practical and accessible approach. ,− By carefully selecting specific elements and controlling their concentrations, the introduction of additional electrons or holes allows for the fine-tuning of electronic band structure, electron density distribution, and other catalyst characteristics. ,− Based on the different supporting materials, it can be generally divided into doping on carbon-based substrates ,,− and metal-based substrates, while the former aims to modulate the embedded metal sites, and the latter activates both the substrate and doping atoms.…”

With the increasingly serious greenhouse effect, the electrochemical carbon dioxide reduction reaction (CO 2 RR) has garnered widespread attention as it is capable of leveraging renewable energy to convert CO 2 into value-added chemicals and fuels. However, the performance of CO 2 RR can hardly meet expectations because of the diverse intermediates and complicated reaction processes, necessitating the exploitation of highly efficient catalysts. In recent years, with advanced characterization technologies and theoretical simulations, the exploration of catalytic mechanisms has gradually deepened into the electronic structure of catalysts and their interactions with intermediates, which serve as a bridge to facilitate the deeper comprehension of structure−performance relationships. Transition metal-based catalysts (TMCs), extensively applied in electrochemical CO 2 RR, demonstrate substantial potential for further electronic structure modulation, given their abundance of d electrons. Herein, we discuss the representative feasible strategies to modulate the electronic structure of catalysts, including doping, vacancy, alloying, heterostructure, strain, and phase engineering. These approaches profoundly alter the inherent properties of TMCs and their interaction with intermediates, thereby greatly affecting the reaction rate and pathway of CO 2 RR. It is believed that the rational electronic structure design and modulation can fundamentally provide viable directions and strategies for the development of advanced catalysts toward efficient electrochemical conversion of CO 2 and many other small molecules.

“…Among them, GO has garnered special attention due to its large lateral size, excellent electronic conductivity, and high stability. 52 Bai et al reported a Co–Co LDH/GO composite, where GO nanosheets were initially sandwiched by ZIF-67 nanocages through facile co-deposition. 53 Subsequently, the ZIF-67 nanocages were converted into Co–Co LDH hollow nanocages via a thermal ion-exchange reaction with Co(NO 3 ) 2 ·6H 2 O.…”

“…Copper (Cu), a well-known metal catalyst in carbon dioxide reduction reaction (CO 2 RR), without which C-C coupling is hard to be realized to obtain high-value multi-carbon products like ethanol and ethylene, [95][96][97][98][99] is also a crucial element for NO 3 RR. [100,101] Nitrate conversion to nitrite has been discovered as a ratedetermining step of NO 3 RR, and Cu is highly effective in promoting this reaction. [51,102,103] Based on the frontier molecular orbital theory, compared with other metal elements, Cu has the highest occupied molecular orbital (HOMO, d-orbital) and simultaneously the lowest unoccupied molecular orbital (LUMO) similar to nitrate (𝜋-orbital) theoretically, meaning that Cu can easily inject electron into the N-O bond of nitrate and activate the NO 3 RR process.…”

Natural nitrogen cycle has been severely disrupted by anthropogenic activities. The overuse of N‐containing fertilizers induces the increase of nitrate level in surface and ground waters, and substantial emission of nitrogen oxides causes heavy air pollution. Nitrogen gas, as the main component of air, has been used for mass ammonia production for over a century, providing enough nutrition for agriculture to support world population increase. In the last decade, researchers have made great efforts to develop ammonia processes under ambient conditions to combat the intensive energy consumption and high carbon emission associated with the Haber‐Bosch process. Among different techniques, electrochemical nitrate reduction reaction (NO3RR) can achieve nitrate removal and ammonia generation simultaneously using renewable electricity as the power, and there is an exponential growth of studies in this research direction. Here we provide a timely and comprehensive review on the important progresses of electrochemical NO3RR, covering the rational design of electrocatalysts, emerging C‐N coupling reactions, and advanced energy conversion and storage systems. Moreover, future perspectives are proposed to accelerate the industrialized NH3 production and green synthesis of chemicals, leading to a sustainable nitrogen cycle via prosperous N‐based electrochemistry.This article is protected by copyright.
