Incorporating H₂O into N, N-dimethylformamide (DMF) enables controlled crystallization, as water's lower boiling point and higher vapor pressure regulate solvent evaporation and film formation. The XRD and SEM analyses of the 3 % H₂O samples show large crystalline sizes, well-formed grains, and smooth surfaces, indicating a significant reduction in defects within the perovskite material.

The influence of UV-PC parameters on the concentration of hydroxyl radicals (·OH) and the polishing performance of SiC was studied. The influence of photocatalytic parameters, including TiO₂ mass fraction, H₂O₂ mass fraction, and light intensity, on the concentration of ·OH was investigated using a spectrophotometric system. Based on this, the polishing experiment was conducted on single-crystal SiC. Results show that material removal rate (MRR) and ·OH concentration were significantly correlated. As the mass fraction of TiO₂, mass fraction of H₂O₂, and light intensity increase, the concentration of ·OH radicals initially rises before declining, while the MRR of SiC initially increases before decreasing. Conversely, the surface roughness Ra of SiC exhibits first decreases before increasing. Under the conditions of 10 wt% TiO₂, 10 wt% H₂O₂, and light intensity of 40 mW/cm², the concentration of ·OH was highest, leading to the most significant fading of the methyl orange (MO) solution. Within 40 min, the degradation rate of the MO solution reached 99.3 %. At this time, the MRR of SiC was highest, reaching 4.05 μm/h, and the surface roughness Ra was lowest, at 1.09 nm.
