Photo-assisted technologies for environmental remediation
Industrial processes can lead to air and water pollution, particularly from organic contaminants such as toluene and antibiotics, posing threats to human health. Photo-assisted chemical oxidation technologies leverage light energy to mineralize these contaminants. In this Review, we discuss the mechanisms and efficiencies of photo-assisted advanced oxidation processes for wastewater treatment and photothermal technologies for air purification. The integration of solar energy enhances degradation efficiency and reduces energy consumption, enabling more efficient remediation methods. We evaluate the technological aspects of photo-assisted technologies, such as photo-Fenton, photo-persulfate activation, photo-ozonation and photoelectrochemical oxidation, emphasizing their potential for practical applications. Finally, we discuss the challenges in scaling up photo-assisted technologies for specific environmental remediation needs. Photo-assisted technologies have demonstrated effectiveness in environmental remediation, although large-scale applications remain constrained by high costs. Future potential applications of photo-assisted technologies will require that technology selection be tailored to specific pollution scenarios and engineering processes optimized to minimize costs.
Combining solar energy with water and air remediation technologies can improve their efficiency. This Review discusses the mechanisms and scalability of photo-assisted technologies for water treatment, including Fenton oxidation, persulfate activation, ozonation and electrochemical oxidation, and photo-assisted thermal technologies for air purification.
Photo-assisted advanced oxidation processes efficiently treat wastewater, whereas photothermal technologies are used in air purification.
The integration of solar energy can enhance efficiency of remediation processes and reduce energy consumption.
Solar energy interacts with chemical oxidation processes, which results in the formation of reactive oxygen species that accelerate the degradation of pollutants.
Wastewater treatments, such as the Fenton oxidation process, consume a high quantity of H2O2 and are kinetically slow. Integrating solar energy accelerates the process.
Using compound parabolic collectors and raceway pond reactors optimizes light harvesting and enables remediation at concentrations of milligrams per litre and below.
Combining different advanced oxidation technologies can help to reduce energy consumption and widen the range of contaminants that can be mineralized.
