“…The loading of metal nanoparticles (Ag, Au, Pt, Bi, etc.) with LSPR on semiconductor to construct plasmonic photocatalysts can prominently enhance photocatalytic activity by improving the light absorption and charge separation efficiency . However, even though the high photocatalytic activities could be obtained by applying above noble metals, their practical applications are restricted by their high cost and resource shortage.…”

Direct efficient employing of solar energy for environmental treatment is obtaining considerable attention at present, where the efficient utilizing the visible (Vis) and near‐infrared (NIR) light is of utmost importance. Herein, the plasmonic MoO2 has been firstly employed to enhance photocatalytic activity in visible and near‐infrared light. By loading MoO2 on BiOBr nanosheets, the plasmonic MoO2/BiOBr photocatalysts have been designed and synthesized through simple hydrothermal method. Localized surface plasmon resonance (LSPR) of MoO2 makes the light absorption range of MoO2/BiOBr extend near‐infrared light. The MoO2/BiOBr nanohybrids display higher photocatalytic performance for rhodamine B (RhB) degradation than that of individual MoO2 and BiOBr under Vis‐ and NIR‐light illumination. About 98 % and 60 % of RhB is degraded in 40 min under >420 nm and >780 nm light illumination. On the one hand, LSPR of MoO2 is beneficial for light absorption and utilization. On the other hand, the synergetic effect between MoO2 and BiOBr facilitates carrier generation, transportation in the interfaces of MoO2 and BiOBr, and reduce carrier recombination. Moreover, the catalytic activity of MoO2/BiOBr nanohybrid almost shows no significant weaken even after five consecutive runs. Our study may open avenues to design the efficient noble metal‐free plasmonic photocatalysts for taking advantage of solar energy efficiently.

“…16,17 Ag/AgCl/MIL-101 hybrid composites were applied for the RhB degradation under visiblelight. 18 In these examples, MOFs supported semiconductor composites shows better photocatalytic performance compared to the unsupported semiconductor materials. Therefore, MOFs are considered to be an ideal support for semiconductor materials for the photocatalytic applications in wastewater treatment.…”

“…[30] In recent reports, this drawback has been (at least partially) overcome by forming composites with other types of material. [84][85][86] In this work, we demonstrate that CuTz-1c an generate COH under irradiation and in the presence of H 2 O 2 through two pathways, as shown in Equations (2) and (3). Consequently,CuTz-1ishighly efficient in producing COH and achieved as uperior photocatalytic activity towards dyes.…”

A copper(I) 3,5-diphenyltriazolate metal-organic framework (CuTz-1) was synthesized and extensively characterized by using a multi-technique approach. The combined results provided solid evidence that CuTz-1 features an unprecedented Cu tz cluster as the secondary building unit (SBU) with channels approximately 8.3 Å in diameter. This metal-organic framework (MOF) material, which is both thermally and chemically (basic and acidic) stable, exhibited semiconductivity and high photocatalytic activity towards the degradation of dyes in the presence of H O . Its catalytic performance was superior to that of reported MOFs and comparable to some composites, which has been attributed to its high efficiency in generating OH, the most active species for the degradation of dyes. It is suggested that the photogenerated holes are trapped by Cu , which yields Cu , the latter of which behaves as a catalyst for a Fenton-like reaction to produce an excess amount of OH in addition to that formed through the scavenging of photogenerated electrons by H O . Furthermore, it was shown that a dye mixture (methyl orange, methyl blue, methylene blue, and rhodamine B) could be totally decolorized by using CuTz-1 as a photocatalyst in the presence of H O under the irradiation of a Xe lamp or natural sunlight.
