“…[107] Luo et al prepared 3D hierarchical porous In electrodes by template-free electrodeposition on Cu meshes. [108] Electrocatalyst materials in both the reports showed excellent formate selectivity (≈90%) and large current density. Their great performances were afforded by the porous structure which not only enlarged electrochemically accessible surface areas, but also induced high local pH and hence suppressed HER.…”

Selective CO2 reduction to formic acid or formate is the most technologically and economically viable approach to realize electrochemical CO2 valorization. Main group metal–based (Sn, Bi, In, Pb, and Sb) nanostructured materials hold great promise, but are still confronted with several challenges. Here, the current status, challenges, and future opportunities of main group metal–based nanostructured materials for electrochemical CO2 reduction to formate are reviewed. Firstly, the fundamentals of electrochemical CO2 reduction are presented, including the technoeconomic viability of different products, possible reaction pathways, standard experimental procedure, and performance figures of merit. This is then followed by detailed discussions about different types of main group metal–based electrocatalyst materials, with an emphasis on underlying material design principles for promoting the reaction activity, selectivity, and stability. Subsequently, recent efforts on flow cells and membrane electrode assembly cells are reviewed so as to promote the current density as well as mechanistic studies using in situ characterization techniques. To conclude a short perspective is offered about the future opportunities and directions of this exciting field.

“…For instance, Bi nanosheets catalyst that are generated from atomic‐thick Bi oxycarbonate nanosheets display a FE HCOO − of ≈100% at −0.9 V and this activity is partly attributed to the presence of Bi(101) and Bi(111) facets, which are demonstrated to lower free energy barrier for formation of *OCHO radical, facilitating CO 2 RR . Similar facet dependent DFT results with Sn, In and Bi catalysts were used as theoretical evidence to justify the catalytic activity of these catalysts for CO 2 RR . In addition, SnO 2 (110) is reported to play a positive role in dictating formate generation during CO 2 RR with a number of literatures with SnO 2 nanoparticle catalysts ascribing the importance of this facet …”

Renewable‐electricity‐powered electrocatalytic CO2 reduction reactions (CO2RR) have been identified as an emerging technology to address the issue of rising CO2 emissions in the atmosphere. While the CO2RR has been demonstrated to be technically feasible, further improvements in catalyst performance through active sites engineering are a prerequisite to accelerate its commercial feasibility for utilization in large CO2‐emitting industrial sources. Over the years, the improved understanding of the interaction of CO2 with the active sites has allowed superior catalyst design and subsequent attainment of prominent CO2RR activity in literature. This review tracks the evolution of the understanding of CO2RR active sites on different electrocatalysts such as metals, metal‐oxides, single atoms, metal‐carbon, and subsequently metal‐free carbon‐based catalysts. Despite the tremendous research efforts in the field, many scientific questions on the role of various active sites in governing CO2RR activity, selectivity, stability, and pathways are still unanswered. These gaps in knowledge are highlighted and a discussion is set forth on the merits of utilizing advanced in‐situ and operando characterization techniques and machine learning (ML). Using this technique, the underlying mechanisms can be discerned, and as a result new strategies for designing active sites may be uncovered. Finally, this review advocates an interdisciplinary approach to discover and design CO2RR active sites (rather than focusing merely on catalyst activity) in a bid to stimulate practical research for industrial application.

“…As mentioned above, pure In catalyst can reach a fair selectivity for HCOOH at high overpotentials (>−1.0 V vs. RHE), in our case, the addition of an appropriate amount of Cu significantly decreases the optimal operation potential for the selective CO 2 ‐to‐HCOOH conversion. This is distinct from a recent paper that formed a thick In 2 O 3 shell on Cu, which only resulted in a maximum HCOOH faradaic efficiency of approximately 40 % …”

Selectively approaching chemicals with one composition-tunable catalysti sa ttractive for practical manufacturing. Bimetallic copper-indium (Cu-In) catalysts have been synthesized by using ac oprecipitation methoda nd found to be among the best reported In-based catalysts for electrochemical CO 2 reduction to CO or HCOOH. By varying the metal ratio, the catalyst can be tuned from ac ore-shell structure that selectively produces CO to aw ell-mixed structure that prefers HCOOH production. The distinct selectivities depend on the structure-sensitive binding strength of keyr eactive intermediates. These findings can benefitthe development of abroader range of selectivity-tunablec atalysts.
