Several strategies can be employed to enhance charge separation in semiconductor-based catalysts:
Heterojunction Formation: Combining two semiconductors with suitable band alignments can facilitate the separation of electron-hole pairs. Surface Modification: Adding co-catalysts or creating surface defects can act as traps for charge carriers, preventing recombination. Doping: Introducing foreign atoms into the semiconductor lattice can create energy levels that aid in the separation of charge carriers. Photonic Structures: Designing photonic structures that enhance light absorption can increase the generation of electron-hole pairs.
