Green DES-mediated preparation of the rose-shaped S-scheme heterojunction photocatalyst (β-Bi

Summary: Imagine creating a microscopic "rose" that can clean pollution using nothing but sunlight. Scientists have developed a new, eco-friendly way to bake these tiny, flower-shaped crystals using "Deep Eutectic Solvents" (DES)—a green alternative to harsh chemicals. These Bismuth-based (β-Bi) structures are designed with a special "S-scheme" internal wiring that allows them to capture light energy more efficiently. The result is a powerful "heterojunction" material that acts like a solar-powered vacuum cleaner for environmental contaminants.
