🔬 What if we could watch photocatalysis happen—one catalyst at a time and in real time? see our new article in Chem "Single-catalyst operando photoluminescence spectroscopy of perovskite quantum-dot-driven photoredox reactions" We use an individual perovskite quantum dot simultaneously as: ✨ a quantum emitter ⚗️ a single photocatalyst 👁️ an operando probe of its own catalytic activity Remarkably, these perovskite QDs are sufficiently robust to operate under realistic reaction conditions while revealing charge-transfer dynamics, particle-to-particle heterogeneity, and degradation at the few-atom level. These insights are fundamentally inaccessible through conventional ensemble measurements sciencedirect.com/science/ar…
