| 總結: | Carbon dioxide reutilization through reduction reaction is one promising alternative to reduce
global warming. Reduction reaction of carbon dioxide is usually based on noble metals or
transition metals. Recently, there is an emergence of promising nickel-based catalysts. This
research focuses on examining nickel-based catalysts. Understanding the mechanism of
reduction reaction on electrochemical catalysts can help in designing optimum catalysts.
This study shows quantitative analysis about selectivity and activity of various nickel-based
catalysts, starting from nickel surface, clusters, and single atom catalysts. Density functional
theory (DFT) method implemented in Quantum Espresso software and computational
hydrogen electrode model are used in this study.
The goal of this thesis research is to learn reaction mechanism of carbon dioxide reduction
reaction by studying its energy diagrams and charges. This study shows how nickel single atom
catalyst outperforms nickel surface and clusters in carbon monoxide production. We also show
how dopants can change the selectivity of carbon dioxide reaction to formate path. This
research can serve as a guidance for catalysts experimentalist to synthesize a more optimum
reduction reaction nickel electrocatalysts in the future. |
