Carbon-supported Ni nanoparticles for efficient CO₂ electroreduction

Abstract

Carbon-coated Ni nanoparticles supported on N-doped carbon enable efficient electroreduction of CO2 to CO comparable to single Ni sites.

Electrochemical production of syngas from CO2at pressures up to 30 bar in electrolytes containing ionic liquid

“…Thus, a commercial zinc foil was used as cathode to develop the process. Although more advanced catalysts are known from the state of the art [23][24][25][26], the goal was to understand the influence of some process parameters of liquid phase electrochemical CO 2 reduction using non-conventional electrolytes, before aiming at better performances. Zinc is a metal very prone to oxidation in air, in contact with moisture and with aqueous electrolytes.…”

A metal–organic framework/polymer derived catalyst containing single-atom nickel species for electrocatalysis

“…2d and S18 †); this is likely due to the dense graphitic carbon layer that protects the NPs. 55,58,59 Upon closer inspection of the CNTs, a considerable amount of single atom nickel species are found distributed throughout the CNTs (Fig. 2e).…”

Metal Ionic Liquids Produce Metal‐Dispersed Carbon‐Nitrogen Networks for Efficient CO2 Electroreduction

“…Up to now, great efforts have been devoted to the fabrication of diverse kinds of M/C−X materials for high‐performance catalytic reactions . Among these metals, Ni, which is a cheap and earth‐abundant transition metal, has been regarded as a promising alternative to noble metals . In general, M/C−X composites are obtained via the pyrolysis of a mixture of carbon precursor material, metal source and heteroatom‐containing chemical .…”

“…[5] Among these metals, Ni, which is a cheap and earth-abundant transition metal, has been regarded as a promising alternative to noble metals. [6][7][8] In general, M/CÀ X composites are obtained via the pyrolysis of a mixture of carbon precursor material, metal source and heteroatom-containing chemical. [9] The method is simple and versatile in synthesizing target M/CÀ X materials, but suffers from the heterogeneity in compositions caused by the poor mixing of the different solid precursors for pyrolysis.…”
