A comparison between 2D and 3D cobalt-organic framework as catalysts for electrochemical CO reduction.

Electrocatalytic CO reduction, as an effective way to reduce the CO concentration, has gained attention. In this study, we prepared ZIF-67 nanoparticles and nanosheets and investigated them as electrocatalysts for CO reduction. It was found that ZIF-67 nanosheets, because of their two-dimensional morphologies, provide more under-coordinated cobalt nodes and have lower overpotentials for both hydrogen evolution and CO reduction reactions.

Elucidating the electronic structures of β-AgMoO and AgO nanocrystals theoretical and experimental approaches towards electrochemical water splitting and CO reduction.

In this paper, we demonstrate a combined theoretical and experimental study on the electronic structure, and the optical and electrochemical properties of β-Ag2MoO4 and Ag2O. These crystals were synthesized using the hydrothermal method and were characterized using X-ray diffraction (XRD), Rietveld refinement, and TEM techniques. XRD and Rietveld results confirmed that β-Ag2MoO4 has a spinel-type cubic structure.

Nanostructured copper molybdates as promising bifunctional electrocatalysts for overall water splitting and CO reduction.

Overall water splitting and CO reduction are two very important reactions from the environmental viewpoint. The former produces hydrogen as a clean fuel and the latter decreases the amount of CO emissions and thus reduces greenhouse effects. Here, we prepare two types of copper molybdate, CuMoO and CuMoO, and electrochemically investigate them for water splitting and CO reduction.
