Despite its advantages, nano crystallization comes with several challenges:
Control Over Size and Shape: Achieving uniform size and shape is difficult but crucial for consistent catalytic performance. Scalability: Scaling up nano crystallization processes from laboratory to industrial scale can be challenging. Stability: Nanocrystals may agglomerate or undergo Ostwald ripening, leading to a loss of catalytic activity over time. Cost: Some nano crystallization methods can be expensive, limiting their commercial viability.
