| Outline of Final Research Achievements |
Continuous flow nanocatalysis by metal nanoparticle catalysts-anchored flow reactors has been regarded as an ideal platform for efficient chemical manufacturing. In this study, the gold nanoparticle catalysts-anchored flow reactor based on wood pulp paper was successfully fabricated by using printing or papermaking processes. The as-prepared ‘paper reactor’ provides hierarchically-interconnected micro- and nanoscale pores, which can act as uniform flow paths and fast diffusion paths, respectively, for efficient access of reactants to metal nanoparticle catalysts. Then, the gold nanoparticles-anchored paper reactor offers much higher catalytic efficiency in 4-nitrophenol reduction process than the state-of-the-art flow reactors. Of special note is that the gold nanoparticles-anchored paper reactor also demonstrates excellent recyclability similar to traditional paper materials. Our findings open new doors for highly-efficient, green, and sustainable chemical manufacturing.
