N-Bridged Co–N–Ni: new bimetallic sites for promoting electrochemical CO₂ reduction

Abstract

Electrochemical CO2 reduction reaction (CO2RR) is of importance for reducing global CO2 emissions. Herein, we reported a high active CO2RR catalyst Co-N-Ni/NPCNSs, which is considered as an advanced single-site catalyst...

Hollow CoFe-layered double hydroxide polyhedrons for highly efficient CO2 electrolysis

“…It further increased as the potential became more negative, and the maximum FE (FE max ) of 86% ± 3% was achieved at −0.9 V vs. RHE. This performance is comparable to the recently reported best value achieved using transition metal/noble metal-based electrocatalysts (Table S1), such as Co-N-Ni bimetallic sites supported on N-doped porous carbon (96.4% at −0.58 V vs. RHE) [44]; Ag 1 -N 3 anchored on porous concave N-doped carbon (95% at −0.37 V vs. RHE) [45] in aqueous solution, and Mo 2 C (90% at −2.24 V vs. saturated calomel electrode (SCE)) [46] in IL electrolyte. In contrast, for the CoFe-LDH/SP reference, the FE max of the CO production was 32% ± 3% and this value is significantly less than that of CoFe-LDH/HP.…”

Organic–Inorganic Hybridization Engineering of Polyperylenediimide Cathodes for Efficient Potassium Storage

“…Recently, Ti 3 C 2 T x MXene, as a rising star, is one of promising candidates for PIBs thanks to its unique merits including superb electronic conductivity, adequate mechanical flexibility/rigidity, large surface area, open layered architecture, and the ability to enhance the stability of cathode electrolyte interphase (CEI) layer [21] . Especially, recent investigations also demonstrate that the N‐doped Ti 3 C 2 T x (N‐Ti 3 C 2 T x ) can be endowed with increased reactivities and electrical conductivity [22–24] . In the regards, it would be even better to enhance electrochemical activities of PDI for K + storage by rationally incorporating the N‐Ti 3 C 2 T x into the PDI.…”

Plasmon Assisted Highly Efficient Visible Light Catalytic CO2 Reduction Over the Noble Metal Decorated Sr-Incorporated g-C3N4

“…The energy shortage driven by the rapid depletion of fossil fuels and the significant rise in atmospheric CO 2 concentration are the main challenges facing mankind these days [1][2][3][4]. This dramatic increase in CO 2 concentration (i.e., from 280 to 410 parts per million (ppm)) has been considered as one of the major contributors to the greenhouse effect that seriously smashed the natural carbon balance and provoked global warming [5,6]. According to the recent reports [7,8], the current CO 2 concentration in the atmosphere exceeded 415 ppm, which is expected to raise up to 500 ppm by the end of 2030.…”
