Area of Science:

• Materials Science
• Nanotechnology
• Chemical Engineering

Background:

• Phenolic resin pyrolysis typically produces isotropic glassy carbon, limiting its high-temperature applications.
• The oxidation behavior of pyrolytic carbon is significantly affected by its microstructure.

Purpose of the Study:

• To investigate the catalytic effects of cupric tartrate on phenolic resin pyrolysis.
• To explore the thermal decomposition, microstructural evolution, and oxidation behavior of phenolic resin-derived carbon.

Main Methods:

• Cupric tartrate was used as a catalyst precursor during phenolic resin pyrolysis.
• In situ formation of copper nanoparticles was observed.
• Microstructural analysis and oxidation behavior were studied.

Main Results:

• Cupric tartrate decomposed into Cu/Cu2O composites, then reduced to Cu nanoparticles.
• In situ Cu nanoparticles catalyzed the growth of carbon nanofibers (CNFs) up to 30-50 μm.
• Cu-catalyzed CNFs enhanced structural ordering (reduced ID/IG ratios) and increased oxidation activation energy.

Conclusions:

• A facile strategy using cupric tartrate as a catalyst precursor for CNF growth from phenolic resin was demonstrated.
• This method enables the construction of low-dimensional carbon nanostructures with improved properties.
• The findings offer a new approach for tailoring pyrolytic carbon for high-temperature applications.
