Designing effective photoreactors involves several challenges: 1. Light Penetration: Ensuring uniform light distribution within the reactor to maximize the efficiency of the photocatalytic process. 2. Catalyst Stability: Photocatalysts can degrade over time under intense light exposure, affecting the long-term performance of the reactor. 3. Scalability: Translating lab-scale photoreactor designs to industrial-scale applications while maintaining efficiency and cost-effectiveness.
