Surface-Oxygen-Rich Bi@C Nanoparticles for High-Efficiency Electroreduction of CO to Formate.

The electrochemical CO reduction reaction (CORR) is a promising strategy to alleviate excessive CO levels in the atmosphere and produce value-added feedstocks and fuels. However, the synthesis of high-efficiency and robust electrocatalysts remains a great challenge. This work reports the green preparation of surface-oxygen-rich carbon-nanorod-supported bismuth nanoparticles (SOR Bi@C NPs) for an efficient CORR toward formate.

A highly porous rht-type acylamide-functionalized metal-organic framework exhibiting large CO uptake capabilities.

A new, highly porous acylamide-functionalized MOF with a (3,24)-connected rht-type network (HNUST-5) has been synthesized and structurally determined using powder X-ray diffraction. HNUST-5 exhibits a high BET surface area of 3643 m g, and a large CO uptake capability (38.9 mmol g under 36 bar) with an excellent selectivity of CO/CH (7.
