Closing the Anthropogenic Chemical Carbon Cycle toward a Sustainable Future via CO₂ Valorization

Abstract

Jiawei Zhang earned his Ph.D. degree in chemical engineering and technology from Nanjing University of Science and Technology in 2019. He joined Hunan University as a postdoctoral fellow in 2019 and then worked as a postdoctoral fellow under the supervision of Prof. Zhiqun Lin at the Georgia Institute of Technology. He is now working in the School of Material Science and Engineering at Hunan University. His current research is focused on nanomaterials and their application in energy storage and conversion.

Design strategies for markedly enhancing energy efficiency in the electrocatalytic CO2 reduction reaction

“…2–4 As future electricity could come from sustainable energy sources such as wind, solar and tidal energy, the CO 2 RR also enables their storage in chemicals, which overcomes the geographic or time constraints during utilization of these renewable sources. 5–7…”

Advances in studies of the structural effects of supported Ni catalysts for CO2hydrogenation: from nanoparticle to single atom catalyst

“…With the rapid development of renewable energy, the heterogeneous hydrogenation of carbon dioxide (CO 2 ) has attracted significantly increasing attention worldwide owing to its potential in large scale utilization of carbon dioxide. 1–4 CO 2 hydrogenation has also been considered to be promising for energy storage. 5–7 Many catalysts have been exploited and reported for CO 2 hydrogenation.…”

“…8–15 In addition, supported nickel catalysts have been employed in the industrial production of syngas (CO and hydrogen) via steam reforming of methane, a reverse reaction of CO 2 hydrogenation to methane, which is normally called CO 2 methanation and well-known as the Sabatier reaction. 3,21 Theoretically, the product of CO 2 hydrogenation over a supported nickel catalyst can be methane, methanol, carbon monoxide through the reverse water gas shift (RWGS) reaction, and formic acid. Methanol, formic acid and carbon monoxide are important intermediates for syntheses of various chemicals.…”

Dynamic Evolution of Active Sites in Electrocatalytic CO2 Reduction Reaction: Fundamental Understanding and Recent Progress

“…[1][2][3] In particular, electrocatalytic CO 2 reduction reaction (CO 2 RR) powered by clean and reproducible electricity, can effectively convert CO 2 into fuels and energy-dense products. [4][5][6][7] It should be noted that compared to other alternative technologies, CO 2 RR possesses inherent advantages such as mild operating conditions, high energy efficiency, tunable reaction rate, and flexible regulation of products distribution by altering applied voltage. [8][9][10][11] Despite the huge prospect, the development of CO 2 RR is still hindered by the challenges from the thermodynamic stability of linear CO 2 molecule and competitive hydrogen evolution reaction (HER).…”
