Researchers are exploring the electrochemical carbon dioxide reduction reaction (CO2RR) to convert CO2 into valuable products. Modulating proton transfer after carbon-carbon coupling is key to enhancing alcohol production and reducing unwanted ethylene formation.
Area of Science:
- Electrochemistry
- Catalysis
- Sustainable Chemistry
Background:
- Electrochemical CO2 reduction (CO2RR) offers a sustainable route to convert CO2 into chemicals and fuels.
- Proton and electron transfer post C-C coupling critically influence CO2RR pathways, impacting C2+ product selectivity.
- Limited reviews focus on post-C-C coupling dynamics and their role in C2+ alcohol selectivity.
Purpose of the Study:
- To review strategies for modulating the post-C-C coupling process in CO2RR.
- To highlight methods for enhancing C2+ alcohol production and suppressing C2H4 formation.
- To provide insights into CO2RR mechanisms and catalyst design for selective alcohol synthesis.
Main Methods:
- Review of recent literature on CO2RR mechanisms and catalyst design.
- Analysis of modulation strategies including interface, defect, morphology, alloying, and surface engineering.
- Discussion of catalytic mechanisms and reaction pathways toward alcohols.
Main Results:
- Regulating proton transfer dynamics post C-C coupling effectively enhances alcohol production.
- Specific strategies like interface engineering, defect engineering, and alloying improve C2+ alcohol selectivity.
- These modulations help suppress the formation of undesired C2H4.
Conclusions:
- Modulating the post-C-C coupling process is a viable strategy for efficient CO2RR toward C2+ alcohols.
- Further research into catalyst design and mechanistic understanding is crucial for optimizing selectivity.
- This review offers guidance for developing catalysts for selective production of valuable C2+ alcohols from CO2.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
