Abstract

Abstract: Inefficient visible light photocatalytic degradation of organic pollutants, such as acetaminophen (ACE) and triclosan (TS), is one of the main limiting factors for implementing cost‐effective metal oxide photocatalyst for large‐scale deployment. Here, a highly efficient CuO thin film photocatalyst is developed through rapid thermal annealing. The CuO thin film is decorated with Pd nanostructures for enhanced visible light degradation of ACE and TS. It is shown that compared to the as‐deposited thin CuO film photocatalyst, the rapid thermal assisted CuO photocatalyst can significantly enhance charge generation and separation efficiency through improvement of crystallinity and reduction of recombination centres. Furthermore, it is demonstrated that the incorporation of Pd nanostructures can considerably increase optical absorption, which further improve the photocatalytic performance through the enhancement of surface plasmon resonance. The CuO film with the 40 s of Pd sputtering (Pd40–CuO) shows the highest performance for photocatalytic degradation of both ACE and TS. The Pd40–CuO film shows good stability and does not show any considerable reduction in photocatalytic activity after five cycles. This indicates the high potential of Pd40–CuO for water and wastewater treatment on industrial scale. Abstract : Application of Pd‐decorated CuO thin film for photocatalytic degradation of acetaminophen and triclosan in aqueous solution is presented. The effect of thermal treatment on the photocatalytic activity of the CuO thin film is investigated. The photocatalytic degradation mechanism is comprehensively discussed in this article. The stability and recycling of photocatalysts are investigated.
