TL;DR: This work proposes a new strategy to covalently graft cobalt porphyrin onto the surface of a carbon nanotube by a substitution reaction at the metal center, providing an effective pathway for the improvement of the performance of electrocatalysts that could inspire rational design of molecular catalysts in the future.

TL;DR: In this article, a cobalt phthalocyanine-based catalyst supported on pyridine-functionalized carbon nanotubes (CoPc-py-CNT) was designed for electrochemical CO2 reduction.

TL;DR: In situ characterization combined with density functional theory (DFT) calculations reveals that heteronuclear coordination modifies the d-states of the metal atom, resulting in a lower free energy barrier in the thermodynamic pathway and a reduced activation energy as well as fortified metal-C bonding in the kinetic pathway.

TL;DR: In this article, a Y2O3-promoted NiO-CeO2 catalyst was proposed and found to exhibit an outstanding methanation activity that is up to three folds higher than NiOCe O2 and six fold higher than NO-Y 2 O3 at mild reaction temperatures.

TL;DR: For the first time, it is reported that by varying the metal ratio, the catalyst can be tuned from a core-shell structure that selectively produces CO to a well-mixed structure that prefers HCOOH production.
