Zinc oxide nanotube array, and preparation method and application thereof

Abstract

The invention provides a zinc oxide nanotube array with zinc oxide nanowires growing at the end. According to the invention, zinc oxide nanotubes are of a hollow structure, and the zinc oxide nanowires are grown on the tube walls of the end parts of the zinc oxide nanotubes. Compared with conventional zinc oxide nanotube / rod arrays, the zinc oxide nanotube array provided by the invention has the following advantages: since a great number of the nanowires are grown on the end parts of the nanotubes, a liquid / gas contact area on the surface of a nano-material is increased, so the degradation efficiency of the material in a photocatalytic reduction reaction is improved, and the self-cleaning ability of the zinc oxide nano-material is also enhanced, thereby meeting the demands of long-term work in special environments.

Description

technical field [0001] The invention relates to the field of nanometer materials / devices, in particular to a nanotube array with nanowires grown on its ends, a preparation method and application thereof. Background technique [0002] With the development of society and economy, environmental pollution is becoming more and more serious, which not only endangers human health, but also hinders economic development. Therefore, looking for new, efficient, economical and cheap semiconductor materials with photocatalytic oxidation is a current research hotspot. Nano-zinc oxide is one of the materials that has attracted much attention. As early as the 1960s, many researchers began to use zinc oxide thin films to prepare various sensors such as photocatalysts. Many scientists also devoted themselves to studying the excellent performance of zinc oxide materials in the direction of electrons and photons, and achieved remarkable results. . With the development of nanotechnology, rese...
