• Capillary microreactor
• Ultra-long grass-like ZnO arrays
• Pt catalysts
• Reduction of o-nitrophenol

Grass-like double-layer ZnO micro-nanostructures in the confined microchannels is fabricated via fluid construction methods, with the vertical height as high as 50 mu m. Subsequently, surface modification of Pt solutions produced uniformly distributed catalytic Pt micro-nanostructures in a facile method. The efficiency of the grasslike catalysts was demonstrated for the continuous reduction reaction of o-nitrophenol and degradation methylene blue. Reaction rates and yields were significantly enhanced and the catalytic structures were recyclable. The results should be significant upon current microfluidic technologies, and exhibit great potentials in continuous flow reactions.
