Pr doping promotes the formation of Pt single atoms by regulating metal-support interaction for remarkable photocatalytic hydrogen production.

Since the metal-support interaction (MSI) has a great influence on the structure and properties of single atom catalysts (SACs), the activity and stability of SACs can be effectively regulated by adjusting the structure of the matrix. Herein, the morphology of surface supported Pt species can be controlled by doping to adjust the properties of TiO support. Specifically, under the same conditions, the Pt species on the Pr doped TiO surface are Pt SAs (Pt/TiO(Pr)), while on the pure TiO surface are particles (Pt/TiO).

Cu surface plasmon resonance promoted charge transfer in S-scheme system enhanced visible light photocatalytic hydrogen evolution.

Reasonably constructing nanocomposite photocatalysts with fast charge transfer and broad solar response capabilities is significant for efficiently converting solar energy into chemical energy. Cu modifies P25/CeO heterojunctions prepared by photodeposition (P25 is commercial TiO). The local surface plasmon resonance (LSPR) effect caused by Cu nanoparticles broadens the spectral response range and generates significant photothermal effects.

Changeable Active Sites by Pr Doping CuSA-TiO Photocatalyst for Excellent Hydrogen Production.

Photocatalytic water splitting for clean hydrogen production has been a very attractive research field for decades. However, the insightful understanding of the actual active sites and their impact on catalytic performance is still ambiguous. Herein, a Pr-doped TiO-supported Cu single atom (SA) photocatalyst is successfully synthesized (noted as Cu/Pr-TiO).

S-scheme CuP/TiO heterojunction for outstanding photocatalytic water splitting.

TiO photocatalysts are of great interest in the fields of environmental purification, new energy and so on, because of their non-toxicity, high stability, high redox ability and low cost. However, the photogenerated carriers are severely recombined, which limits the application of TiO photocatalysts. Herein, S-scheme CuP/TiO heterojunction composites were successfully synthesized by a simple and efficient microwave hydrothermal method, and the results show that the hydrogen production rate of CuP/TiO is 5.
