Plasmonic CsPbBr3–Au nanocomposite for excitation wavelength dependent photocatalytic CO2 reduction

Hybrid Plasmonic Nanomaterials for Hydrogen Generation and Carbon Dioxide Reduction

“…CsPbBr 3 nanocubes were decorated with AuNPs (see panel i in Figure 4 b) and tested toward their CO 2 reduction performance with both visible–NIR light (λ > 420 nm) and light below the bandgap of CsPbBr 3 (λ > 580 nm). 155 The results are in agreement with the findings of Xu et al 158 (discussed above for H 2 production), where the increase in activity due to the presence of the AuNPs could be attributed to both charge transfer from the perovskite to Au and charge transfer from Au to the perovskite, dependent on which entity was optically excited. For full visible–NIR light illumination, the introduction of AuNPs yields a 3.2-fold enhancement.…”

“…This may be one of the reasons why there is no demonstration of hydrogen production on halide perovskites yet, and that the first demonstration of CO 2 reduction in such a system was published in 2020. 155 …”

Construction of a ternary WO3/CsPbBr3/ZIF-67 heterostructure for enhanced photocatalytic carbon dioxide reduction

“…Correspondingly, the total electron consumption yield (Yield electron ) of the CO 2 reduction reaction was calculated via the following formula: Yield electron = 2Yield CO + 8Yield CH 4 . The isotope experiment was conducted with 13 CO 2 molecules as the isotopic tracer under the same photocatalytic conditions as mentioned above, and the products were detected using gas chromatography-mass spectrometry (QP2010).…”

“…Consequently, the rational design of PVK-based heterogeneous photocatalysts made by coupling PVK with selected functional materials is of supreme importance to boost their photocatalytic performances [11]. Inspired by this, various PVK-based heterostructures (i.e., CsPbBr 3 /g-C 3 N 4 [12], CsPbBr 3 /Au [13], CsPbBr 3 /Bi 2 WO 6 [14], and CsPbBr 3 /TiO 2 [15]) have been developed, and enhanced CO 2 reduction activity has been achieved. A Z-scheme heterojunction contains a two-photon excitation process, and it maintains the high redox capacity of photocarriers with a high solar energy utilization efficiency [16][17][18].…”

2D-C3N4 encapsulated perovskite nanocrystals for efficient photo-assisted thermocatalytic CO2 reduction

“…All-inorganic perovskites, for example cesium lead tribromide (CsPbBr 3 ), have emerged as a promising type of photocatalyst for the CRR, owing to their long photogenerated carrier diffusion length, tunable size, wide light-absorption range, etc. 5 c ,10 CsPbBr 3 perovskites have been widely explored in composites with other materials, such as g-C 3 N 4 , 11 graphene oxide 5 a ,12 and TiO 2 (ref. 13) to construct heterojunctions for photocatalytic CO 2 reduction.…”
