Global climate change and energy concerns have led to a surge of interest in the electrochemical conversion of carbon dioxide (CO2) to fuels such as methane and ethanol. Metals such as copper, tin, gold, and others have proven effective as catalysts for reducing CO2 to a wide spectrum of products. Interestingly, it has recently been shown that oxidizing some of these metals further enhances their catalytic activities and selectivities. Oxidation seems to play a fundamental, but poorly understood, role in modulating the reactivity of these catalysts. In this Review, recent progress towards understanding the effect of oxygen, surface morphologies, and local pH gradients on the catalysis of CO2 reduction is discussed.

“…The obtained results were shown in Figure b. It could be seen that the formate FE (91 %) and current density (22 mA cm −2 ) could keep stable without any significant decreasing during the electrolysis for 23 h. The result is comparable with those reported in the previous literature, demonstrating that Bi 2 O 3 ‐A electrode catalyst has a potential application for CO 2 electroreduction.…”

“…It could be seen that O1s peak consisted of two peaks in the two samples. The peak at 535.7 eV or 534.8 eV can be ascribed to the oxygen attached to the Bi−O bond, while the other peak at 536.8 or 535.8 eV can be assigned to adsorbed oxygen,, respectively. In Figure b, the O1s peak for Bi 2 O 3 ‐A nanoparticles had a higher binding energy component at the range of 525.6–537 eV than the thin nanorods.…”

“…Some investigations have indicated that Bi catalysts could effectively catalyze CO 2 reduction to form CO with high Faradaic efficiencies (FEs) in an aprotic solvent (e. g., MeCN) containing ion liquids ,. More interestingly, some researchers have recently reported that Bi with different microstructures as electrodes could catalyze the electroreduction of CO 2 to formate with high selectivity and high FE in aqueous solutions . These investigations greatly promote the development of Bi‐based electrocatalysts.…”

“…However, it should be noted that some key problems have not still be solved, such as poor catalytic stability and low electrolytic current density. In the previous investigations, the stability of Bi electrode catalysts was only examined for 7∼12 h and current density was relatively low (within the range 3∼15 mA cm −2 ), which could not meet the requirement of practical applications. So Bi‐based electrocatalysts need to be improved greatly.…”

In this paper, Bi2O3 electrocatalysts for the electroreduction of CO2 to formate were synthesized with different morphologies, including nanoparticles and thin nanorods. Comparatively, Bi2O3 nanoparticles have higher catalytic activity than Bi2O3 thin nanorods. The Faradaic efficiency of formate formation at a moderate potential of −1.2 vs. RHE in aqueous solution could reach 91 %. In addition, a maximum current density for formate production of up to 22 mA cm−2 was achieved, which is almost 3 times higher than that of Bi2O3 thin nanorods. In particular, the catalytic activity of the Bi2O3 nanoparticle catalyst was almost stable over a 23‐hour period of electrolysis, exhibiting its application prospect in the electroreduction of CO2 to formate.

Recently, a large number of nanostructured metal-containing materials have been developed for the electrochemical CO 2 reduction reaction (eCO 2 RR). However, it remains a challenge to achieve high activity and selectivity with respect to the metal load due to the limited concentration of surface metal atoms. Here, it is reported that the bismuth-based metal-organic framework Bi(1,3,5-tris(4-carboxyphenyl)benzene), herein denoted Bi(btb), works as a precatalyst and undergoes a structural rearrangement at reducing potentials to form highly active and selective catalytic Bi-based nanoparticles dispersed in a porous organic matrix. The structural change is investigated by electron microscopy, X-ray diffraction, total scattering, and spectroscopic techniques. Due to the periodic arrangement of Bi cations in highly porous Bi(btb), the in situ formed Bi nanoparticles are well-dispersed and hence highly exposed for surface catalytic reactions. As a result, high selectivity over a broad potential range in the eCO 2 RR toward formate production with a Faradaic efficiency up to 95(3)% is achieved. Moreover, a large current density with respect to the Bi load, i.e., a mass activity, up to 261(13) A g −1 is achieved, thereby outperforming most other nanostructured Bi materials.
