What are the Challenges in Photocatalytic Water Splitting?
Despite its potential, several challenges hinder the practical application of photocatalytic water splitting. These include:
- Efficiency: The efficiency of current photocatalysts is relatively low. Improving light absorption, charge separation, and the catalytic activity of photocatalysts is essential. - Stability: Many photocatalysts degrade over time or under continuous illumination, reducing their long-term viability. - Cost: Developing cost-effective materials that can be produced at scale remains a significant challenge. - Scalability: Translating laboratory-scale successes to industrial-scale applications poses technical and economic hurdles.
