Solar energy is abundant, but its direct utilization faces challenges related to storage and conversion efficiency. Catalysis offers solutions to these problems.
1. Solar-to-Fuel Conversion: Artificial photosynthesis aims to mimic natural photosynthesis using sunlight, water, and carbon dioxide to produce fuels like hydrogen or methanol. Catalysts are essential for optimizing the efficiency of the light-absorbing and reaction processes.
2. Dye-Sensitized Solar Cells (DSSCs): These solar cells use a photosensitive dye and a catalyst to convert sunlight into electricity. The catalyst, often platinum, helps in the reduction and oxidation processes within the cell, enhancing the overall efficiency.
