In-situ study of the hydrogen peroxide photoproduction in seawater on carbon dot-based metal-free catalyst under operation condition
Hydrogen peroxide (H 2 O 2 ) photoproduction in seawater with metal-free photocatalysts derived from biomass materials is a green, sustainable, and ultra environmentally friendly way. However, most photocatalysts are always corroded or poisoned in seawater, resulting in a significantly reduced catal...

| description | Hydrogen peroxide (H
2
O
2
) photoproduction in seawater with metal-free photocatalysts derived from biomass materials is a green, sustainable, and ultra environmentally friendly way. However, most photocatalysts are always corroded or poisoned in seawater, resulting in a significantly reduced catalytic performance. Here, we report the metal-free photocatalysts (RUT-1 to RUT-5) with
in-situ
generated carbon dots (CDs) from biomass materials (Rutin) by a simple microwave-assisted pyrolysis method. Under visible light (
λ
≥ 420 nm, 81.6 mW/cm
2
), the optimized catalyst of RUT-4 is stable and can achieve a high H
2
O
2
yield of 330.36 µmol/L in seawater, 1.78 times higher than that in normal water. New transient potential scanning (TPS) tests are developed and operated to
in-situ
study the H
2
O
2
photoproduction of RUT-4 under operation condition. RUT-4 has strong oxygen (O
2
) absorption capacity, and the O
2
reduction rate in seawater is higher than that in water. Metal cations in seawater further promote the photo-charge separation and facilitate the photo-reduction reaction. For RUT-4, the conduction band level under operating conditions only satisfies the requirement of O
2
reduction but not for hydrogen (H
2
) evolution. This work provides new insights for the
in-situ
study of photocatalyst under operation condition, and gives a green and sustainable path for the H
2
O
2
photoproduction with metal-free catalysts in seawater. |
