Abstract
Dye wastewater and energy shortage are two large inhibition factors, and photocatalytic applications have proven to be an effective strategy to overcome the above crises in various areas such as wastewater remediation and H2 production. Herein, the TiO2 NTs/Cu2O photocatalyst was created by depositing Cu2O onto TiO2 nanotube arrays (TiO2 NTs), with the number of successive ionic layer adsorption and reaction (SILAR) deposition cycles playing a significant role in determining the photoelectrochemical performance. The TiO2 NTs/Cu2O (9) showed the outstanding visible light photocurrent, pollutant removal and H2 evolution. TiO2 NTs/Cu2O (9) successfully removed MO, RhB, MB and Cr(VI) with the degradation efficiencies of 99.32 %, 69.63 %, 99.27 % and 72.55 %, and it also showed the optimal H2 evolution rate (49.67 μmol·cm−2·h−1). Furthermore, the Z-scheme photocatalytic mechanism was proposed, and the dye decomposition was primarily caused by the presence of O2 radicals.
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
