A Facile Method for Preparation of Cu₂O-TiO₂ NTA Heterojunction with Visible-Photocatalytic Activity.

ABSTRACT: Based on highly ordered TiO₂ nanotube arrays (NTAs), we successfully fabricated the Cu₂O-TiO₂ NTA heterojunction by a simple thermal decomposition process for the first time. The anodic TiO₂ NTAs were functioned as both "nano-container" and "nano-reactors" to load and synthesize the narrow band Cu₂O nanoparticles. The loaded Cu₂O expanded absorption spectrum of the TiO₂ NTAs from ultraviolent range to visible light range. We found that the Cu₂O-TiO₂ NTA heterojunction films had visible activity towards photocatalytic degrading methyl orange (MO). The photocatalytic abilities of the Cu₂O-TiO₂ NTA heterojunction films were found increased with the Cu₂O content f
