“…Instead, we focused on the steps we used after the formation of the HCOO* species because its formation on both surfaces is facile. This consideration is also consistent with experimental studies that have shown formic acids as the dominant products on the Pb-based electrodes [24][25][26][27]. In order to predict the intermediates/products that would form after the HCOO*, we first needed to establish the limiting potential at which HCOO* is formed.…”

“…Pb and Sn have similarly low standard potentials as Cu and have been widely studied as electrode catalysts for CO 2 [24][25][26][27][28][29][30][31]. The general observation from those studies is that formic acid is the dominant product with a high Faradaic yield (~90%) on both electrodes.…”

A DFT study of CO2 electrochemical reduction on Pb(211) and Sn(112)

Electrochemical reduction of CO 2 has the benefit of turning greenhouse gas emissions into useful resources. We performed a comparative study of the electrochemical reduction of CO 2 on stepped Pb(211) and Sn(112) surfaces based on the results of density functional theory slab calculations. We mapped out the potential energy profiles for electrochemical reduction of CO 2 to formate and other possible products on both surfaces. Our results show that the first step is the formation of the adsorbed formate (HCOO*) species through an Eley-Rideal mechanism. The formate species can be reduced to HCOO  through a oneelectron reduction in basic solution, which produces formic acid as the predominant product. The respective potentials of forming HCOO* are predicted to be 0.72 and 0.58 V on Pb and Sn. Higher overpotentials make other reaction pathways accessible, leading to different products. On Sn(112), CO and CH 4 can be generated at 0.65 V following formate formation. In contrast, the limiting potential to access alternative reaction channels on Pb(211) is 1.33 V, significantly higher than that of Sn. electrochemical reduction, reaction mechanism, carbon dioxide, formate, DFT

“…Moreover, there may be hydrogenocarbon reduction competing with HER since the supporting electrolyte was KHCO 3 in this system. It was reported by Innocent et al 33 with the help of in situ IR reflectance spectroscopy that HCO 3 − was the reactive species for the formation of formate under the same operating conditions. When the electrolyte solution was saturated with CO 2 , there was a main competition between the HER and CO 2 reduction at the electrodes.…”

How to take advantage of CO 2 has been one of the main issues to be addressed around the world. Although there are many methods to convert CO 2 to organic fuel, the efficiency is still not high enough for practical application. Herein, we have accomplished better conversion of CO 2 by the combination of metal electrode and semiconductor thin films responsive to visible light. First, the deposition of p-type and n-type Cu 2 O thin films onto a Cu substrate is successfully achieved. Then, the prepared Cu/Cu 2 O samples are used for catalytic reduction of CO 2 in photoelectrochemical systems in comparison with that in photochemical and electrochemical systems. The results show that CH 4 and C 2 H 4 are the major hydrocarbon gas products, and the prepared Cu/Cu 2 O samples have much higher selectivity for C 2 H 4 formation compared with the pure Cu electrode. The best yield for CO 2 reduction is obtained in the photoelectrochemical system under visible light. Additionally, CO 2 conversion efficiency over the Cu/Cu 2 O (p-type) electrode is much higher than that over Cu/Cu 2 O (n-type) with similar morphology. The morphology of Cu 2 O has an effect on the CO 2 reduction activity in the photoelectrochemical system as well. The related mechanism is discussed in detail especially for the reaction in the beginning 15 min. The study will provide us a new way to utilize solar light for efficient conversion of CO 2 into organic fuel.

Multivariate calibration method for mass spectrometry of interfering gases such as mixtures of CO, N₂, and CO₂

et al. 2018

View full text Add to dashboard Cite

A multivariate calibration method for mass spectrometry is presented that enables a quantitative analysis of gas mixtures containing interfering gases that contribute to the same mass‐to‐charge ratios at nominal resolution. Multiple calibration gas mixtures with linearly independent compositions are used in order to obtain the calibration constants for the contribution of each gas to each of the mass‐to‐charge ratio peaks. The method was successfully applied to the quantitative detection of CO in a mixture with CO2 and N2, which represents a difficulty commonly encountered in heterogeneous catalysis and electrocatalysis research.
