What is Laser Technology in Catalysis?
Laser technology in catalysis involves the use of laser light to enhance or initiate chemical reactions. Lasers can provide precise control over reaction conditions, such as temperature, pressure, and photon energy, which can significantly impact the efficiency and selectivity of catalytic processes.
How Does Laser Technology Work in Catalysis?
Lasers generate coherent, monochromatic light that can be directed at catalytic materials. This light can excite electrons, break chemical bonds, or induce other changes in the catalyst or reactant molecules. By tuning the wavelength and intensity of the laser, researchers can selectively activate specific reactions or reaction pathways.
