Photoreactors and photocatalysis are two related fields in the discipline of photochemistry, where light is harnessed to activate chemical reactions. This family of technologies is increasingly framed in the context of sustainable clean energy, environmental protection, and industrial applications. In this session, the principles and practical applications of these light-driven processes in a green and sustainable future will be presented.
Photochemistry is the study of how light interacts with molecules to induce chemical changes. Photosynthesis is one example, where plants use light-induced reactions to convert sunlight into energy. However, photochemistry is not limited to these natural processes. It forms the foundation of various new technologies designed to capture sunlight and transform it into forms usable by humans. Technologies such as solar cells and photonic devices are based on the principles of photochemistry.
Building on photochemistry, photocatalysis incorporates specific materials to catalyze reactions under light exposure. This technology holds significant potential for practical applications, such as water purification, by decomposing harmful impurities within water systems, and in producing clean, renewable energy through water splitting to create hydrogen fuel. Photocatalysis offers excellent solutions to global challenges, including pollution and energy consumption.
Photoreactors are designed systems where light-driven reactions are optimized through controllable variables, such as the intensity of illumination, reaction time, and catalyst surface area. They are crucial for environmental applications, effectively degrading organic pollutants in water and air to control pollution. Photoreactors are also used in the energy sector to produce valuable chemical fuels and synthesize new materials through light-induced reactions. Their role is especially relevant for industrial-scale applications, as they facilitate the scaling up of photocatalytic processes.
In this session, I will outline the synergies between photochemistry and photocatalysis, with photoreactors serving as a bridge between the two, demonstrating their collective contribution to advancements in clean energy and environmental sustainability. Attendees will learn about cutting-edge research and technological developments related to light-driven energy approaches and their promising role in a sustainable future.
Through discussions on innovative applications and technology, this session provides a deeper understanding of how light can be harnessed to transform chemical processes, influencing industries from energy production to waste management.
