Abstract

This study aims to develop a high-efficiency solar energy utilization system for water purification by synthesizing porous CuInS₂ (CIS) nanosheet arrays on a compacted stainless steel mesh (CSSM) using a facile solvothermal method. The CIS/CSSM system leverages interfacial heat to drive water evaporation and enhance photodegradation via photothermal effects. The porous architecture of both the CSSM and the black CIS nanosheets significantly improves light collection efficiency, achieving a solar absorption rate of 97.3 %, thereby facilitating efficient photothermal conversion. Under simulated 1-sun illumination, the system attains an evaporation rate of 1.43 kg m⁻² h⁻¹ with a high evaporation efficiency of 93.01 %. The cost-effective CSSM possesses robust chemical stability, making the CIS/CSSM an efficient solar purification system capable of distilling clean water from seawater, river water, and highly acidic/alkaline solutions. Furthermore, the system demonstrates excellent photothermal catalytic degradation, achieving 88.1 % degradation of ciprofloxacin solution. In outdoor sunlight, the system simultaneously maintains an evaporation rate of 1.23 kg m⁻² h⁻¹ and a photothermal degradation efficiency of 80.7 %, highlighting its potential application in water purification. This study integrates photothermal catalysis with solar-driven interfacial evaporation, offering a novel and efficient approach for wastewater treatment and water purification.

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
