Photocatalytic Applications of Perovskite Materials

Photocatalytic applications of perovskite materials exploit their exceptional light-harvesting and charge-transport properties to drive chemical transformations under illumination. Both metal halide and oxide perovskites exhibit tuneable bandgaps, high extinction coefficients and long charge-carrier diffusion lengths that render them ideal for solar-to-chemical energy conversion. Recent advances have tackled intrinsic limitations—such as water instability and lead toxicity—through compositional engineering, surface passivation and integration into protective matrices. These strategies have enabled a broad range of photocatalytic reactions, including hydrogen evolution, CO₂ reduction, organic synthesis and pollutant degradation, underscoring the global significance of perovskite photocatalysts for sustainable fuel production and environmental remediation.

Research from Nature Portfolio

Recent studies have demonstrated that perovskite nanocrystals can function as highly efficient photoredox catalysts for fundamental organic transformations. Colloidal lead-halide perovskite nanocrystals were shown to drive C–C, C–N and C–O bond-forming reactions with excellent selectivity under visible-light illumination, benefiting from facile band-edge tuning and stable performance in organic media. A novel single-atom catalyst approach anchored Pt–I₃ species on an all-inorganic Cs₂SnI₆ framework, achieving record hydrogen evolution rates and outstanding stability in acidic aqueous solutions. In parallel, surface-encapsulated CsPbBr₃ photoanodes integrated with carbon-based protectants realised prolonged oxygen evolution in water, validating the direct use of halide perovskites for solar fuel generation.
