What are the challenges associated with ALD in catalysis?
Despite its advantages, ALD does come with certain challenges: - Cost: The equipment and precursor materials can be expensive. - Process Complexity: The process parameters need to be meticulously optimized for each material and application. - Deposition Rate: ALD is relatively slow compared to other deposition techniques, which can be a limitation for large-scale production. - Thermal Sensitivity: Some substrates may not withstand the temperatures required for certain ALD processes.
