“…BIEF engineering also shines in electrocatalytic CO 2 RR and offers great prospects for raising the selectivity of target products. Electrocatalytic CO 2 RR could convert CO 2 into value-added chemicals or fuels, − which involves 2, 4, 6, 8, 12, or even more electron-transfer processes . Taking formate as an example, its production needs two electrons to take part in , CO 2 + * ⇌ *CO 2 (1); *CO 2 + e – → *CO 2 •– (2); *CO 2 •– + HCO 3 – → *OCHO • + CO 3 2– (3); *OCHO • + e – → *OCHO – (4); *OCHO – → HCOO – + * (5).…”

To utilize intermittent renewable energy as well as achieve the goals of peak carbon dioxide emissions and carbon neutrality, various electrocatalytic devices have been developed. However, the electrocatalytic reactions, e.g., hydrogen evolution reaction/ oxygen evolution reaction in overall water splitting, polysulfide conversion in lithium− sulfur batteries, formation/decomposition of lithium peroxide in lithium−oxygen batteries, and nitrate reduction reaction to degrade sewage, suffer from sluggish kinetics caused by multielectron transfer processes. Owing to the merits of accelerated charge transport, optimized adsorption/desorption of intermediates, raised conductivity, regulation of the reaction microenvironment, as well as ease to combine with geometric characteristics, the built-in electric field (BIEF) is expected to overcome the above problems. Here, we give a Review about the very recent progress of BIEF for efficient energy electrocatalysis. First, the construction strategies and the characterization methods (qualitative and quantitative analysis) of BIEF are summarized. Then, the up-to-date overviews of BIEF engineering in electrocatalysis, with attention on the electron structure optimization and reaction microenvironment modulation, are analyzed and discussed in detail. In the end, the challenges and perspectives of BIEF engineering are proposed. This Review gives a deep understanding on the design of electrocatalysts with BIEF for nextgeneration energy storage and electrocatalytic devices.

“…Very recently, they also summarized CO 2 conversion by electro-and photoelectrocatalysis, emphasizing the importance of operando characterization theoretical simulations [55]. Li et al briefly reviewed bimetallic chalcogenides for ECR application in the past five years [56]. They disclosed that hybridization between metal atoms, such as that of intermetallic compounds, heterostructures and metal doping, shows positive effects on ECR selectivity and activity.…”

Electrocatalytic CO2 reduction (ECR) is an attractive approach to convert atmospheric CO2 to value-added chemicals and fuels. However, this process is still hindered by sluggish CO2 reaction kinetics and the lack of efficient electrocatalysts. Therefore, new strategies for electrocatalyst design should be developed to solve these problems. Two-dimensional (2D) materials possess great potential in ECR because of their unique electronic and structural properties, excellent electrical conductivity, high atomic utilization and high specific surface area. In this review, we summarize the recent progress on 2D electrocatalysts applied in ECR. We first give a brief description of ECR fundamentals and then discuss in detail the development of different types of 2D electrocatalysts for ECR, including metal, graphene-based materials, transition metal dichalcogenides (TMDs), metal–organic frameworks (MOFs), metal oxide nanosheets and 2D materials incorporated with single atoms as single-atom catalysts (SACs). Metals, such as Ag, Cu, Au, Pt and Pd, graphene-based materials, metal-doped nitric carbide, TMDs and MOFs can mostly only produce CO with a Faradic efficiencies (FE) of 80~90%. Particularly, SACs can exhibit FEs of CO higher than 90%. Metal oxides and graphene-based materials can produce HCOOH, but the FEs are generally lower than that of CO. Only Cu-based materials can produce high carbon products such as C2H4 but they have low product selectivity. It was proposed that the design and synthesis of novel 2D materials for ECR should be based on thorough understanding of the reaction mechanism through combined theoretical prediction with experimental study, especially in situ characterization techniques. The gap between laboratory synthesis and large-scale production of 2D materials also needs to be closed for commercial applications.

“…Electrochemical CO 2 reduction (ECR) to value-added compounds can be driven by electricity generated from green and renewable sources, using hydrogen generated in situ from water electrolysis instead of blue H 2 derived from fossil fuels, thus providing a potential route to ameliorate the greenhouse effect and close the carbon cycle. [1][2][3][4][5][6][7][8] Among the various products of ECR, CO is one of the most practical target compounds, and is a critical feedstock for multiple important reactions, such as the water-gas shift reaction, Fischer-Tropsch process, and methanol synthesis, among others. Converting CO 2 to CO via electrolysis is posited to proceed through three steps by transferring two electrons: [9][10][11][12] A CO 2 molecule is first transformed to a *COOH intermediate (* represents an adsorbed site) via either a concerted proton/electron transfer or formation of a CO 2 *À anion, which is subsequently converted to *CO after attacking of the oxygen atom in the *COOH by the 2 nd proton/electron pair, followed by desorption of *CO from the catalyst surface.…”

Electrochemical CO2 reduction (ECR) is recognized as a sustainable and promising approach for the production of high‐value chemicals. To facilitate widespread application of this technology, the design and construction of efficient cathodic electrocatalysts is critically important. Here we report the synthesis of atomically dispersed manganese on nitrogen‐doped porous carbon (Mn SAs/NC) using a facile and scalable annealing method for catalyzing the ECR reaction. The as‐obtained Mn SAs/NC delivers high activity and selectivity toward CO formation with a faradaic efficiency of 80.5±0.6%, over 5 times that of bare NC. The high activity is preserved even after 10 h of continuous polarization. The catalytic properties of our cost‐effective Mn SAs/NC catalyst are readily tuned by regulating the nitrogen configurations and the percentage of Mn SAs via modulation of the nitrogen precursor and the thermal treatment conditions.
