With the development of society and growing concern about environmental issues, continuous flow catalytic reactors have gained significant interest due to their resource-efficient advantages over traditional batch devices. In this study, we employed a facile one-step in situ reduction approach construct highly dispersed gold nanoparticles loaded on regenerable bacterial cellulose nanofiber (BCN) heterogeneous catalysts. These catalysts, combination with nanoceramic membrane pore size 1 nm, formed fully mixed system that was favorable for efficient catalysis selective reactions nitrophenol. The reaction demonstrated remarkable activity toward nitrophenol at low reductant dosages (<5 equiv), achieving 95% conversion 99% selectivity aniline product 10 min under room temperature conditions. Furthermore, operations maintained stable minimal catalyst loss after 120-h test were 3 times more time-efficient than operations. Additionally, monitoring could be conducted through ultraviolet (UV) spectroscopy. A environmentally friendly strategy present designing future applications.
