Synergistic coupling of interface ohmic contact and LSPR effects over Au/Bi₂₄O₃₁Br₁₀ nanosheets for visible-light-driven photocatalytic CO₂ reduction to CO.

ABSTRACT: The challenge of synergistically optimizing different mechanisms limits the further improvement of plasmon-mediated photocatalytic activities. In this work, an Au/Bi₂₄O₃₁Br₁₀ composite, combining an interface ohmic contact and localized surface plasmon resonance (LSPR), is prepared by a thermal reduction method. The LSPR effect induces the local resonance energy transfer effect and the local electric field enhancement effect, while the interface ohmic contact forms a stronger interface electric field. The novel synergistic interaction between the interface ohmic contact and LSPR drives effective charge separation and provides more active sites for the adsorption and activation of CO₂ with improved photocatalytic efficiency.
