Continuous-flow microreactors offer increased reactivity and reusability via unique reaction pathways to address a wide range of practical nanocatalysis problems.However,only limited platforms exist to employ these microreactors for versatile nanocata-lytic reactions.In this work,we conformally anchored nickel oxide (NiO) nanosheets onto quartz fibers (QFs),which exhibited a high catalytic activity using the hydrogenation of 4-nitrophenol (4-NP) as a model reaction in a batch reaction study.More importantly,we demonstrated that fiber-based QF@NiO composites (e.g.,cotton,fabric,belt,felt) can be integrated as versatile platforms to develop microreactors for continuous-flow catalytic applications including hydrogenation reactions and dye-catalyzed degradation.This fiber-based three-dimensional (3D) nanocatalyst architecture effectively drives continuous-flow catalytic reactions with unprecedented efficiency due to the easy diffusion of reactant molecules into the fibrous structure,allowing contact with catalytic active sites.Our approach to continuous-flow microreactor design uses surface hybridization as a guideline to immobilize nanocatalysts onto the QFs.These QF-based platforms,coupled with rational design,are expected to be applied to a wide range of nanocatalytic reactions.
