Sustainable upcycling of difficult-to-recycle PET/cotton fabrics into acid-modulated Cu-BDC adsorbents with morphology-driven gas selectivity

Key Points

• Enhanced gas selectivity is achieved in Cu-BDC adsorbents derived from difficult-to-recycle PET and cotton fabrics, leading to sustainable upcycling solutions.
• The modification of morphology through acid modulation demonstrates significant impact on the adsorption efficiency of various gas molecules.
• Utilizing challenging materials like PET and cotton for adsorbent production highlights innovative recycling opportunities within waste management frameworks.
• This method supports sustainable practices, potentially reducing environmental waste through effective material repurposing.
