报告摘要:

The quest for clean hydrogen from sunlight and water hinges on two often underestimated factors: the liquid environment and the electronic driving force. Electrolytes do far more than conduct ions-they set the stage for diffusion, buffering, and resistance losses that can make or break device efficiency. By deliberately tailoring these properties, we can overcome pH gradients, reduce voltage penalties, and enable stable operation at high current densities. This perspective shifts attention from catalysts alone to the full reaction environment, where electrolyte engineering becomes a powerful design principle.

Equally transformative is the ability to map semiconductor energetics and control surface catalyst decoration, which together determines the quasi-Fermi level. This quantification directly reveals the driving force of photogenerated carriers for hydrogen and oxygen evolution. By uniting electronic mapping with electrolyte control, we gain a holistic view of nanoscale electrolysis in particulate photocatalysts. These insights open a clear path toward rational design of solar-to-hydrogen systems that are efficient, durable, and scalable.
