Multifunctional Perovskites: From Batteries to Green Pharma
The Challenge Zinc-air batteries are a promising alternative to Lithium-ion, but they suffer from sluggish oxygen reduction/evolution reactions (ORR/OER). Commercial catalysts like Platinum (Pt) are expensive and unstable. 1. Synthesis: The “Black Powder” Challenge Incorporating volatile alkali metals (like Potassium) into the Perovskite lattice is notoriously difficult due to their high vapor pressure at calcination temperatures ($>800^{\circ}C$). I solved this by developing a low-temperature ($265^{\circ}C$) hydrothermal route, effectively “trapping” the Potassium ions within the lattice. ...
