Special Issue Information

Dear Colleagues,

Wastewaters often contain toxic organic pollutants which can have a harmful effect on human health and the environment. Heterogeneous photocatalytic processes have gained increasing interest as an efficient method to degrade a wide range of organic pollutants. The process includes the illumination of semiconductors and the generation of charge carriers (electrons and holes) which are capable of initiating a wide range of oxidative and reductive reactions. The major limiting factors affecting photocatalytic activity include (1) charge separation and transport, (2) charge carrier lifetimes, (3) surface chemical reaction, and (4) visible light absorption. The development of novel catalytic systems with improved redox properties and superior visible light activity is a great challenge today. This Special Issue on "Photocatalysis Application in Environment Science" seeks high-quality research articles, as well as review articles, focusing on the latest advances in photocatalytic processes and their application in environmental sciences. It is expected that this issue will stimulate further research activities in this area and shed light on the main scientific and technological problems in photocatalytic application in environmental sciences.

The topics of interest include:

  • Design of novel photocatalytic materials with improved structural, optical, and textural properties and superior photocatalytic activity;
  • Application of photocatalytic material for wastewater treatment and treatment of air pollutants;
  • Theoretical calculation, kinetics, and mechanism modeling of photocatalytic reactions.

The increasing demand for efficient wastewater treatment technologies, driven by global population growth and industrialisation, highlights the necessity for advanced, reliable solutions. This study investigated the efficacy of a slurry photocatalytic membrane reactor (PMR) for the advanced removal of organic pollutants, quantified via chemical oxygen demand (COD), under natural and simulated solar light irradiation. Employing two variants of iron-doped titania as photocatalysts and a polysulfone-based polymeric membrane for the separation process, the investigation showcased COD removal efficiencies ranging from 66–85% under simulated solar light to 52–81% under natural sunlight over a 7 h irradiation period. The overall PMR system demonstrated COD removal efficiencies of 84–95%. The results confirmed the enhanced photocatalytic activity afforded by iron doping and establish solar-powered slurry PMRs as an effective, low-energy, and environmentally friendly alternative for the advanced treatment of municipal wastewater, with the research providing valuable insights into sustainable water management practices.
