Solvent-Free Ball Milling Synthesis of Water-Stable Tin-Based Pseudohalide Perovskites for Photocatalytic CO₂ Reduction.

ABSTRACT: A pseudohalide (SCN^-) tin-based perovskite material using a solvent-free ball milling method is developed. The synthesized perovskite exhibits long-term water stability and demonstrated significant photocatalytic activity in reducing CO₂ to CO under light irradiation. The structural transition from nanoparticles to planar perovskites is achieved by varying the ratios of dimethylammonium (DMA) and formamidinium (FA) cations, which is confirmed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. The surface elemental distribution, absorption spectra, band gap and energy levels estimations using energy-dispersive X-ray spectroscopy (EDS), Kubelka-Munk function, and ultraviolet photoelectron spectroscopy (UPS) are thoroughly investigated.
