Abstract

In this work, we constructed a red phosphorus (RP)/TiO₂ composite system via a chemical vapor deposition strategy. The evolution of the fibrous phased RP nanorods on the surface of anatase TiO₂ spheres was rationally adjusted by controlling the composition of precursors. The optimal RP/TiO₂ composite exhibited a significantly enhanced visible-light-driven photocatalytic H₂ generation rate of 681 μmol h⁻¹ g⁻¹. The tightly interior surface bonding between RP and TiO₂ greatly promoted the efficient charge transfer and redistribution by suppressing the charge recombination and self-trapping processes within TiO₂, resulting in prolonged lifetimes of the active charges during the photocatalytic process as investigated in detailed using femtosecond time-resolved transient absorption (fs-TA) spectroscopy.
