2022 Year-end party

25 Jan 2022

Tue

At the end of the year of Ox, we went to a famous restaurant near Hsinchu, which offers gorgeous roast ducks with two ducks and five eats. We also tasted various delicious seafood, including shrimp and crab. The advisor prepared a poke-a-red-envelop game. Each student got their own red envelop and the luck for the year of Tiger. Happy Lunar New Year!!!

Prof. Hung's first-author paper in Nat. Commun.

10 Feb 2022 Thur 

Prof. Hung published "A Metal- Supported Single-Atom Catalytic Site Enables Carbon Dioxide Hydrogenation" as the first author in Nature Communications. 

The following is the publication information:

Hung, S.-F.; Xu, A.; Wang, X.; Li, F.; Li, Y.; Wick, J.; Cervantes, E. G.; Rasouli, A. S.; Li, C. Y.; Luo, M.; Nam, D.-H.; Wang, N.; Peng, T.; Yan, Y.; Lee, G.; Sargent, E. H. A Metal- Supported Single-Atom Catalytic Site Enables Carbon Dioxide Hydrogenation. Nature Commun. 2022, 13, 819.

https://www.nature.com/articles/s41467-022-28456-9

Abstract:

Nitrogen-doped graphene-supported single atoms convert CO2 to CO, but fail to provide further hydrogenation to methane – a finding attributable to the weak adsorption of CO intermediates. To regulate the adsorption energy, here we investigate the metal-supported single atoms to enable CO2 hydrogenation. We find a copper-supported iron-single-atom catalyst producing a high-rate methane. Density functional theory calculations and in-situ Raman spectroscopy show that the iron atoms attract surrounding intermediates and carry out hydrogenation to generate methane. The catalyst is realized by assembling iron phthalocyanine on the copper surface, followed by in-situ formation of single iron atoms during electrocatalysis, identified using operando X-ray absorption spectroscopy. The copper-supported iron-single-atom catalyst exhibits a CO2-to-methane Faradaic efficiency of 64% and a partial current density of 128 mA cm−2, while the nitrogen-doped graphene-supported one produces only CO. The activity is 32 times higher than a pristine copper under the same conditions of electrolyte and bias.

Abstract:

We develop a flow cell for operando X-ray absorption spectroscopy for CO2RR, providing the identical catalytic environment with the electrochemical measurement. Two model catalysts, metallic copper and copper hydroxidem are investigated. These catalysts undergo a remarkable reduction to a metallic state in the flow cell during CO2RR.

About the Cover:

Copper-based catalysts offer an opportunity to realize the carbon neutralizing process via CO2RR to yield high-value hydrocarbons. The unique mixed-valence environment of the Cu2O(110) can promote the coupling of H2CCO and CO. This discovery unveils the concept that the mixed-valence region due to the residual oxygen is a critical factor for C3 products.

About the Cover:

A flow cell was developed for operando X-ray absorption spectroscopic studies during carbon dioxide reduction reaction. It provides an identical catalytic environment with the electrochemical cell. Two model catalysts, metallic copper and copper hydroxide, were investigated. The linear combination fitting and wavelet analysis of the operando spectra unveiled that the copper catalysts undergo a remarkable reduction to a metallic state in the flow cell during carbon dioxide reduction reactionrather than maintaining positive valences.

DOI:

Abstract:

Carbon dioxide reduction reaction (CO2RR) is a promising approach to accomplishing net zero CO2 emissions. Among CO2RR catalysts, nitrogen-doped graphene-supported single-atom catalysts show a remarkable conversion rate from CO2to CO; however, the low production amount has been limited using the conversion H cell, hindering its industrial development. In this work, we synthesize a nitrogen-doped graphene-supported nickel-single-atom catalyst and conduct CO2RR in a flow cell, exhibiting a CO2-to-CO Faradaic efficiency of 96% and a partial current density of 144 mA cm-2. It can also achieve the highest partial current density of 204 mA cm-2 with a turnover frequency of 7852 h-1. According to the techno-economic analysis, these preeminent activities meet the industrial criteria (Faradaic efficiency > 60% and partial current density > 100 mA cm-2). This activity enhancement using a flow system can significantly accelerate net-zero CO2 emission realization.
