Design of metal-free photocatalysts with customized chemical structure and nano-architecture is promising for photocatalytic hydrogen peroxide (H2O2) production.Herein,for the first time,mesoporous resorcinol-formaldehyde (MRF) nanobowls with optimized benzenoid-quinoid donor-accepter (D-A) couples have been synthesized via an assembly-hydrothermal-etching process as high-performance photocatalysts for H2O2 production in a sacrificial agentfree system.At the hydrothermal temperature of ～ 250 ℃,MRF-250 exhibits optimized structural features including a large surface area,suitable D-A couple ratio,enhanced light absorption,charge-hole separation and mass transfer.Thus,MRF-250 shows an unexpected H2O2 yield of 19.4 mM·g-1·h-1 in pure water,outperforming other RF samples prepared under different conditions and superior to most reported metal-free photocatalysts without the aid of sacrificial agents.Our work paves the way towards the elaborate design of highly effective metal-free photocatalysts for H2O2 production.
