Relay Catalysis in Selective Transformations of C₁ into C₂₊ Molecules

Area of Science:

• Catalysis
• Chemical Synthesis
• Materials Science

Background:

• C1 molecules (CO, CO2, CH4, CH3OH) are key feedstocks for sustainable fuels and chemicals.
• Selective activation of C-O/C-H bonds and C-C formation are significant catalytic challenges.
• Traditional methods like Fischer-Tropsch synthesis often lack selectivity or require multiple steps.

Purpose of the Study:

• To review advances in C1 chemistry utilizing relay and tandem catalysis.
• To analyze the design principles and applications of relay catalysis.
• To highlight the potential of relay catalysis for synthesizing fuels and chemicals.

Main Methods:

• Development of bifunctional/multifunctional catalysts (metals and zeolites).
• Application of relay catalysis for selective hydrogenation and synthesis.
• Integration of sequential reactions in single catalysts or reactors.

Main Results:

• Successful application of relay catalysis for selective synthesis of hydrocarbon fuels.
• Extension of relay catalysis to produce high-value chemicals (olefins, aromatics, higher alcohols) from CO, CO2, and CH4.
• Demonstration of controllable product selectivity through integrated reaction pathways.

Conclusions:

• Relay catalysis offers a powerful strategy for efficient C1 conversion.
• This approach overcomes selectivity and processing limitations of conventional methods.
• Relay catalysis holds significant promise for future sustainable chemical production.
