Electronic and geometric modulations of catalysts for electrochemical CO₂ reduction reaction

Abstract

Electrocatalytic CO2 reduction reaction (CO2RR) converts CO2 into high-value-added chemicals using clean and renewable energy, making it one of the most promising strategies for addressing present-day energy and environmental crises....

Structural engineering of catalysts for ammonia electrosynthesis from nitrate: recent advances and challenges

“…These changes include valence, electronegativity, charge density and polarization, which can strengthen orbital hybridization between the electrocatalyst and nitrate or intermediates, thereby improving its adsorption strength. 80 In single-atom catalysts, the surrounding matrix is an effective parameter for modulating the electronic states of the single metal atom due to strong interaction with the coordinated elements. Similarly, regulation of the size of the catalyst to clusters can tune the electronic states of active sites, leading to better activity.…”

High-performance artificial leaf: from electrocatalyst design to solar-to-chemical conversion

“…29,30 In order to mitigate the increasing greenhouse effect and achieve the global zero-carbon goal, the development of efficient ways to reduce CO 2 to high value-added chemicals is important for both scientific research and practical applications. 31–35…”

“…29,30 In order to mitigate the increasing greenhouse effect and achieve the global zerocarbon goal, the development of efficient ways to reduce CO 2 to high value-added chemicals is important for both scientific research and practical applications. [31][32][33][34][35] As multiple proton-coupled electron transfer (PCET) processes are involved in the CO 2 RR, a wide range of products can be generated, 36 including carbon monoxide (CO), formic acid (HCOOH), methanol (CH 3 OH), ethylene (C 2 H 4 ), ethanol (CH 3 CH 2 OH), n-propanol (CH 3 CH 2 CH 2 OH) and many others (Fig. 3).…”

Highly Selective Acetylene‐to‐Ethylene Electroreduction Over Cd‐Decorated Cu Catalyst with Efficiently Inhibited Carbon‐Carbon Coupling

“…The incorporation of a secondary metal into catalysts has been identified as a key strategy for optimizing the electronic structure of the active sites, ultimately enhancing catalytic performance [15] . However, there is a lack of studies exploring the use of a secondary metal to modify Cu‐based catalysts with the aim of improving EAR activity and product selectivity.…”

“…The incorporation of a secondary metal into catalysts has been identified as a key strategy for optimizing the electronic structure of the active sites, ultimately enhancing catalytic performance. [15] However, there is a lack of studies exploring the use of a secondary metal to modify Cu-based catalysts with the aim of improving EAR activity and product selectivity. Herein, secondary metal screening tests were conducted on Cd, In, and Sn, metals recognized for their inactivity in electrochemical hydrogen evolution and CÀ C coupling reactions.…”
