Quantum Dot Catalysis: A New Light on Reactions
Quantum Dots: The Tiny Titans Revolutionizing Photocatalysis Imagine a world powered by clean, sustainable energy, where pollutants are eliminated from the environment, and groundbreaking medical treatments become a reality. This seemingly futuristic vision is closer than you think, thanks to a fascinating field of nanotechnology called quantum dots (QDs) and their remarkable application in photocatalysis. What are Quantum Dots? Quantum dots are tiny semiconductor nanocrystals, typically measured in nanometers (billionths of a meter). These microscopic particles exhibit unique optical and electronic properties due to quantum confinement effects – the phenomenon where electrons are confined within such small spaces that their energy levels become quantized. This quantization allows QDs to absorb specific wavelengths of light and emit light at different wavelengths,...
