Electrocatalysis CO₂ to Tunable Syngas upon Fe Clusters Catalyst Dispersed on Bamboo-like NCTs

Abstract

Herein, we report a catalyst of Fe@NBCT with a high performance in electrocatalytic CO2 to syngas with tunable H2/CO ratio. Both in situ synchrotron radiation Fourier transform infrared spectra (SR-FTIR) and density functional theory (DFT) calculation proved that the differing N-doping carbon matrix and Fe nanoclusters (NCs) play dramatic roles in tuning the ratio of syngas during the electrocatalytic carbon dioxide reduction reaction (EC-CO2RR) process.

Electrochemical CO2reduction with ionic liquids: review and evaluation

“…Syngas compositing of H 2 and CO, as an important feedstock in industry, is mainly derived from coal or natural gas, which are non-renewable resources. [97][98][99] CO 2 R potentially provided a more energy-efficient method to produce syngas with different ratios by adjusting the reaction environment, including the electrolyte and catalyst. [100][101][102][103][104][105][106] Among them, H 2 /CO with a ratio of 1 : 1, i.e., H 2 /CO (1 : 1) is suitable for the Fischer-Tropsch hydrocarbon synthesis, while H 2 /CO (2 : 1) can be used to synthesize formaldehyde via hydroformylation.…”

Intermetallic Compound with CuNi Sites for Enhancing the Selectivity of Electrochemical CO2 Conversion

“…As we all know, CO 2 RR is a complex process involving multielectron transfer resulting in several intermediates and various products. 10,11 Thus, designing and constructing efficient electrocatalysts with high activity and selectivity to speed up the reaction kinetics are emergency pursuits. In recent years, a variety of electrocatalysts have been proposed, such as metal-doped and metal-free carbon materials.…”

“…Especially electrocatalytic CO 2 reduction reaction (EC–CO 2 RR) has become one of the hottest topics among them. As we all know, CO 2 RR is a complex process involving multielectron transfer resulting in several intermediates and various products. , Thus, designing and constructing efficient electrocatalysts with high activity and selectivity to speed up the reaction kinetics are emergency pursuits. In recent years, a variety of electrocatalysts have been proposed, such as metal-doped and metal-free carbon materials. − Various products have been obtained through different reaction routes, such as CO and HCOOH require a two-electron transfer, methane requires an eight-electron-transfer process, and C 2+ products are obtained by C–C coupling, based on different kinds of catalysts. − Moreover, CO 2 RR occurs in an aqueous solution along with the hydrogen evolution reaction (HER) competitive process, which decreases the faradaic efficiency of the overall electron transfer, making the reduction further complicated. − All in all, the design of efficient catalysts with high selectivity is still an enormous challenge.…”

All‐Solid‐State Synthesis of High‐Performance Electrocatalysts for Oxygen Reduction Reaction Derived From g‐C3N4 and Cobalt Phthalocyanine

“…[8,9] These non-precious metal ORR catalysts can be mainly categorized into two types: 1) metal-free carbon-based materials with regulated microstructures and doping elements (such as nitrogen, phosphorus, boron, etc.). [10][11][12][13] Lv et al used triacetylene benzene to selectively dope hydrogen-substituted graphdiyne (HsGDY) by cross-coupling reaction, and the synthesized pyridine N-HsGDY in the alkaline medium exhibited higher electrocatalytic activity for ORR than Pt/C, as well as the higher stability and methanol tolerance than Pt/C. [14] Moreover, its ORR catalytic performance in the acidic medium is comparable to Pt/C.…”
