Article Abstract
Today, the fabrication of carbon monoxide (CO) in industry customarily necessitates elevated temperature and pressure. Concurrently, the harnessing of infrared (IR) light, which constitutes ≈50% of solar energy, has predominantly remained unexploited due to a pronounced contradiction between the utilization of IR light and CO photoreduction. To break the above limitation, a dual-plasmon resonance conductor with a metallic nature is designed, which realizes the synthesis of CO with 100% selectivity from infrared photothermal catalytic reduction of atmospheric carbon dioxide (CO). Taking the Au particles loaded CuTe nanowires as an example, the surface dual-plasmon resonance coupling effect can optimize the three critical processes of CO photoreduction, in which it is illustrated that the dual-plasmon resonance effect lowers the thermodynamic reaction energy barrier, facilitating the selective generation of CO products. Consequently, the Au-CuTe nanowires manifest a CO evolution rate of ≈2.7 µmol g h with 100% selectivity for atmospheric CO reduction driven by IR light, several times higher than that of the CuTe nanowires.

Photocatalysis, particularly plasmon-mediated photocatalysis, offers a green and sustainable approach for direct nitrogen oxidation into nitrate under ambient conditions. However, the unsatisfactory photocatalytic efficiency caused by the limited localized electromagnetic field enhancement and short hot carrier lifetime of traditional plasmonic catalysts is a stumbling block to the large-scale application of plasmon photocatalytic technology. Herein, we design and demonstrate the dual-plasmonic heterojunction (Bi/Cs WO ) achieves efficient and selective photocatalytic N oxidation.

A bifunctional tunable metamaterial composed of pattern metal structure, graphene, and strontium titanate (STO) film is proposed and studied numerically and theoretically. The dual plasmon-induced transparency (PIT) window is obtained by coupling the bright state cut wire (CW) and two pairs of dark state dual symmetric semiring resonators (DSSRs) with different parameters. Correspondingly, slow light effect can also be realized.

Flower-like metallic nanocrystals have shown great potential in the fields of nanophononics and energy conversion owing to their unique optical properties and particular structures. Herein, colloid Au nanoflowers with different numbers of petals were prepared by a steerable template process. The structure-adjustable Au nanoflowers possessed double plasmon resonances, tunable electric fields, and greatly enhanced SERS and photocatalytic activity.

The dual plasmons (Bi, Ag)-based direct Z-scheme BiOCl/AgCl heterojunction ultrathin nanosheets are successfully synthesized by hydrothermal combined with solid-state reduction strategy. The plasmons Ag and Bi are formed during solid-state reduction process, which are firmly anchored on surface of BiOCl and AgCl, respectively, and favors the charge transfer obviously. Experiments results confirm the formation of heterojunction ultrathin nanosheets with the main size of 200∼300 nm and the thickness of <10 nm.
