Photocatalysis Research
LumeDEL’s fiber-coupled LEDs provide stable, high-radiant power illumination at targeted wavelengths, supporting advanced photocatalysis research and applications.
Photocatalysis Research
A photocatalyst is a photoactive material that facilitates a chemical reaction by contributing energy harvested from incident light. Illumination at the proper wavelength puts the photocatalyst into an excited state. It transfers that energy to the precursor elements and molecules so that the reaction occurs faster, or at a lower temperature or pressure. At this point, the photocatalyst relaxes back to steady state, ready for the next cycle.
Photocatalysis has a number of important industrial, life sciences, and scientific applications:
-
Water splitting, a nonpolluting method to produce clean hydrogen for use in hydrogen fuel cells
-
Antibacterial and antiviral fields for air, surface, and water disinfection
-
Cancer treatment, particularly with nano photocatalysts and photo-redox catalysis used to combat hypoxic tumors
-
Synthesis of complex and often highly functionalized molecules for development of new pharmaceuticals and agrochemicals
-
Support of “circular chemistry” in pursuit of a “circular economy” in which there is zero waste
Fiber-coupled LEDs provide ideal light sources for the research and product development environment. They’re compact, efficient, and provide narrowband spectral coverage ranging from the UV-A spectral region throughout visible wavelengths (365-600 nm).
