Abstract

The use of layered double hydroxides for photocatalytic for H₂O₂ production is innovatively demonstrated. Facet-dependent spatial charge separation enables maximized carrier utilization efficiency. The unique role of intercalated nitrate in promoting electron-hole separation and facilitating intermolecular electron transfer is unveiled. A record-high H₂O₂ production rate of 28.7 mmol g^-1 h^-1 with 3.92% solar-to-chemical efficiency is achieved.
