What Are the Challenges in Chemical Etching for Catalysis?
While chemical etching offers numerous benefits, it also presents some challenges:
- Selectivity: Achieving high selectivity in etching to avoid unwanted material removal can be difficult. - Uniformity: Ensuring uniform etching across the entire substrate can be challenging, especially for large or complex surfaces. - Environmental Concerns: The use of chemical etchants can raise environmental and safety concerns, requiring proper handling and disposal.
