Transformation of glass fiber reinforced epoxy from waste printed circuit boards to adsorbents for effective CO 2 storage in abandoned mines
Key Points
This research aims to convert waste printed circuit boards into effective adsorbents for CO2 storage in abandoned mines.
Used ultrasonication to enhance surface area of FR-4 PCB-derived porous carbons
Applied PEI functionalization to increase CO2 affinity
Evaluated trade-offs in porosity and CO2 uptake
Ultrasonication significantly increased the surface area of the adsorbents
CO2 uptake improved with PEI functionalization despite some porosity loss
Optimized conditions showed enhanced CO2 affinity, making these adsorbents promising for storage applications
Abstract
Ultrasonication enhances surface area and CO 2 uptake of FR-4 PCB-derived porous carbons, while PEI functionalization increases CO 2 affinity with porosity trade-offs.
