Abstract:
We employ a colloidal crystal templating approach to fabricate ordered macro‐mesoporous CsPbBr3 and demonstrate its superior photocatalytic activity compared to its non‐templated counterpart in the degradation of an organic pollutant. The presented templating approach reduces charge carrier diffusion pathways and increases the surface area of the halide perovskite. Furthermore, the crystal structure, and the morphology of the templated halide perovskite are stable under photocatalytic conditions, which results in a constant photocatalytic performance in recycling experiments. The presented concept is applicable for other photocatalytic reactions and can thus advance the novel field of halide perovskites in photocatalysis.
