Nanopaper based on Ag/TiO2 nanobelts heterostructure for continuous-flow photocatalytic treatment of liquid and gas phase pollutants

► The photocatalytic activity of TiO2 nanobelts is evidently enhanced by the heterostructures between Ag nanoparticles and TiO2 nanobelts. ► The nanopapers based on Ag/TiO2 nanobelt heterostructures are fabricated via a modified paper-making process. ► A continuous flow photocatalytic reactor is designed. ► The TiO2 nanopapers in the microreactor show an excellent continuous photocatalytic performance for liquid and gas phase pollutants. ► The Ag/TiO2 nanobelts nanopaper shows a good antibacterial effect.
