Graphitic carbon nitride (g-C3N4) is known to photogenerate hydrogen peroxide in the presence of hole quenchers aqueous environments. Here, g-C3N4 photocatalyst embedded into a host polymer intrinsic microporosity (PIM-1) provide recoverable heterogenized photocatalysts without loss activity. Different types (including Pt@g-C3N4, Pd@g-C3N4, and Au@g-C3N4) different are investigated. Exploratory experiments yield data that suggest binding quencher either (i) directly by adsorption onto (as shown for α-glucose) or (ii) indirectly absorption microporous environment Triton X-100) enhances overall photochemical H2O2 production process. The amphiphilic molecule X-100 interact only weakly with but strongly PIM-1, resulting accumulation enhanced due host.
