Cross-Linked ZnO Nanowalls Immobilized onto Bamboo Surface and Their Use as Recyclable Photocatalysts

Abstract EN

A novel recyclable photocatalyst was fabricated by hydrothermal method to immobilize the cross-linked ZnO nanowalls on the bamboo surface.

The resultant samples were characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), and Fourier transformation infrared (FTIR) techniques.

FTIR spectra demonstrated that the cross-linked wurtzite ZnO nanowalls and bamboo surface were interconnected with each other by hydrogen bonds.

Meanwhile, the cross-linked ZnO nanowalls modified bamboo (CZNB) presented a superior photocatalytic ability and could be recycled at least 3 times with a photocatalytic efficiency up to 70%.

The current research provides a new opportunity for the development of a portable and recycled biomass-based photocatalysts which can be an efficiently degraded pollutant solution and reused several times.
