A simple approach was used to create an environmentally friendly dip catalyst by incorporating gold nanoparticles (AuNPs) into bacterial cellulose (BC) via glycol chitosan (GCS), which acted as both a reducing and self-crosslinking agent. The BC-GCS-AuNPs dip catalyst was analyzed using UV–Vis spectroscopy, FTIR, SEM, XRD, and TEM to confirm the formation of AuNPs and GCS self-crosslinking within the BC network. The catalyst efficacy was tested for converting 4-nitrophenol (NP) to 4-amino phenol (AP). Results demonstrated excellent catalytic performance, achieving up to 98 % within 5 min. The dip catalyst present an appealing option for green and sustainable catalysis due to its outstanding performance, stability, and reusability.
