“…lower Sc ion content, the fluctuation is still small due to the intact crystal structure and there being fewer vacancies. For BZT ceramic samples with more Sc ions, more donor ions will produce more vacancies and grain boundaries, which will affect ion displacement polarization and electron displacement polarization in the higher frequency portion, and this will show large fluctuations in the dielectric spectrum [38]. Figure 11 shows the hysteresis loops of BZT-xmol % ceramics measured at 1 kHz at room temperature.…”

BaZrxTi1−xO3 (BZT) ceramics with different concentrations of Sc ions were prepared, and the effect of doping concentration on the crystal substitution type of BZT was studied. The substitution position of the Sc ion in BZT was related to its concentration. When the concentration of Sc ions was low (<1.0 mol %), it showed B-site substitution; otherwise, Sc ions showed A-site substitution. In addition, the effects of the Sc ion concentration on the sintering temperature, crystal structure, microstructure, and properties of BZT were also studied. The results showed that the introduction of Sc ions can reduce the sintering temperature to 1250 °C. When the concentration of Sc ions was 1.0 mol % and 2.0 mol %, the high dielectric constants of BZT were 14,273 and 12,747, respectively.

Organic–inorganic hybrid perovskite ferroelectric has gained significant attention for its structural flexibility and diversity. They can directly utilize metal nodes and organic groups as active sites in catalysis. Additionally, their ferroelectric polarization occurs around these active sites, significantly enhancing catalytic activity and demonstrating immense potential for applications. However, their catalytic applications remain underexplored. This work marks the first utilization of the molecular perovskite ferroelectric [3,3‐difluorocyclobutylammonium]2CuCl4 (Cu‐DFCBA) as a catalyst for alkane oxidation. Under ultrasonic stimulation, it achieved a remarkable turnover number as high as 2402. Compared to inorganic ferroelectrics like lithium niobate (LiNbO3), the molecular ferroelectric exhibited a 1200‐fold increase in catalytic activity. This highlights Cu‐DFCBA's robust ferroelectric properties and underscores the vast potential of molecular ferroelectrics in catalysis, guiding future system designs.
