“…As such, it was determined that mass transport of CO 2 , rather than the catalytic properties of the electrode, were the limiting factor for the rate of CO evolution. Even higher pressures of CO 2 (up to 30 bar) were applied to a membrane electrode assembly incorporating a Ni NC catalyst by Proietto et al [193] In line with the above results. A higher CO 2 pressure correlated with enhanced CO production, whilst the manipulation of process parameters (namely, the CO 2 pressure and the applied current density) could yield a syngas ratio of 2, with a high syngas productivity up to 18 mol h À 1 m À 2 .…”

Achieving decarbonization through zero net CO2 emissions requires commercially viable application of waste CO2, throughout the transition to renewable and low‐carbon energy sources. A promising approach is the electrochemical carbon dioxide reduction reaction (CO2RR), which when powered with renewable electricity sources, provides a pathway for the conversion of intermittent renewable energy and waste CO2 into value‐added chemicals and fuels. However, as CO2RR is accompanied by the competing hydrogen evolution reaction (HER) due to the presence of water, an opportunity is presented to generate a mixture of CO and H2, also known as synthesis gas or syngas – the building block of various oxy‐hydrocarbon products. The aim of this review is to analyze both Power‐to‐CO and Power‐to‐Syngas studies, in order to classify and discuss the active sites for both CO and H2 generation through a new lens, providing insights into the structure‐activity correlations and facilitating the design of more active syngas electrocatalysts in the future. Through an evaluation of the economic viability of syngas generation, we determine that the carbon capture cost is a key parameter, with improvements in catalyst activity, catalyst impurity tolerance, and electrolyzer technology necessary for significant improvement in the economics of electrocatalytic syngas generation.

“…178,179 The effects of CO 2 pressure (P CO2 ) and catalyst loading (CL) on the H 2 /CO ratio were evaluated. 172 When P CO2 and CL are fixed, the ratio of H 2 /CO increases with the increase of |j|, and the maximum value is about 7.5. Importantly, the maximum production of syngas can reach 18 mol h −1 m −2 (P CO2 = 30 bar; |j| = 195 mA cm −2 ).…”

The excessive use of nonrenewable energy has brought about serious greenhouse effect. Converting CO2 into high‐value‐added chemicals is undoubtedly the best choice to solve energy problems. Due to the excellent cost‐effectiveness and dramatic catalytic performance, nickel‐based catalysts have been considered as the most promising candidates for the electrocatalytic CO2 reduction reaction (eCO2RR). In this work, the electrocatalytic reduction mechanism of CO2 over Ni‐based materials is reviewed. The strategies to improve the eCO2RR performance are emphasized. Moreover, the research on Ni‐based materials for syngas generation is briefly summarized. Finally, the prospects of nickel‐based materials in the eCO2RR are provided with the hope of improving transition‐metal‐based electrocatalysts for eCO2RR in the future.
