MoSe<sub>2</sub>‐Sensitized Water Splitting Assisted by C<sub>60</sub>‐Dendrons on the Basal Surface
To facilitate water splitting using MoSe<sub>2</sub> as a light absorber, we fabricated water-dispersible MoSe<sub>2</sub>/C<sub>60</sub>-dendron nanohybrids via physical modification of the basal plane of MoSe<sub>2</sub>. Upon photoirradiation, the mixed-dimension MoSe<sub>2</sub>/C<sub>60</sub> (2D/0D) heterojunction generates a charge-separated state (MoSe<sub>2</sub>⋅<sup>+</sup>/C<sub>60</sub>⋅<sup>-</sup>) through electron extraction from the exciton in MoSe<sub>2</sub> to C<sub>60</sub>. This process is followed by the hydrogen evolution reaction (HER) from water in the presence of a sacrificial donor (1-benzyl-1,4-dihydronicotinamide) and co-catalyst (Pt-PVP). The apparent quantum yields of the HER were estimated to be 0.06 % and 0.27 % upon photoexcitation at the A- and B-exciton absorption peaks (λ<sub>max</sub>=800 and 700 nm), respectively.
