“…The factors responsible for the enhanced activity can be explained in detail as follows: (a) The SPR effect of Bi loaded on the nanosheets improved the light absorption and response of the composite; (b) the hot electrons produced simultaneously led to a temperature rise, thereby promoting the electron transfer and photocatalysis efficiency; (c) the carrier separation was improved due to the energy band bending showcased by the composite at the interface. Such synergistic use of the SPR effect has also been reported in other cases of photocatalysis, , especially by Au and is worth exploring further in the field of LHP research.…”

Lead halide perovskite (LHP) nanocrystals have emerged as promising candidates for photocatalytic reduction of CO2 into fuels such as methane (CH4) and carbon monoxide (CO) due to their several unique properties such as a tunable bandgap, high absorption coefficients across a broad solar spectrum, long carrier diffusion length, higher carrier mobility, etc. However, following the facile and controllable synthesis of LHP nanocrystals, even though variations in size, morphology, and structural properties are possible, the impact of such variations on their photocatalytic ability has not been properly discussed or overviewed. This perspective delves into the intricate interplay between structural and surface alterations of lead halide perovskite (LHP) nanocrystals, shedding light on their consequential impacts on photocatalytic CO2 reduction. Furthermore, it explores the underlying mechanisms and reaction factors governing CO2 reduction pathways, including adsorption, activation, and conversion processes, elucidating how structural and surface modifications can tailor these processes to enhance photocatalytic efficiency. Overall, this perspective offers valuable insights into designing next-generation LHP nanocrystals with enhanced photocatalytic CO2 reduction performance through deliberate structural and surface engineering strategies, thereby contributing to the advancement of sustainable energy technologies.

“…Metal bismuth (Bi) is an ideal choice to take the place of noble metals due to its lower cost and strong plasmonic effect [28][29][30]. Most importantly, Bi can be easily self-reduced onto Bi 2 MoO 6 by an in situ solvothermal process with its unique advantages of the intimate interfacial contact between Bi and Bi 2 MoO 6 due to the same containing elements [31][32][33].…”

The photocatalytic nitrogen reduction reaction (NRR) in aqueous solution is a green and sustainable strategy for ammonia production. Nonetheless, the efficiency of the process still has a wide gap compared to that of the Haber–Bosch one due to the difficulty of N2 activation and the quick recombination of photo-generated carriers. Herein, a core-shell Bi@Bi2MoO6 microsphere through constructing Schottky junctions has been explored as a robust photocatalyst toward N2 reduction to NH3. Metal Bi self-reduced onto Bi2MoO6 not only spurs the photo-generated electron and hole separation owing to the Schottky junction at the interface of Bi and Bi2MoO6 but also promotes N2 adsorption and activation at Bi active sites synchronously. As a result, the yield of the photocatalytic N2-to-ammonia conversion reaches up to 173.40 μmol g−1 on core-shell Bi@Bi2MoO6 photocatalysts, as much as two times of that of bare Bi2MoO6. This work provides a new design for the decarbonization of the nitrogen reduction reaction by the utilization of renewable energy sources.

“…14 Bi NPs can demonstrate the localized surface plasmon resonance (LSPR) effect and further enhance the visible light absorption capability. 28,29 However, both Bi NPs and Bi 2 S 3 nanorods have a natural tendency to agglomerate during hydrothermal synthesis due to their elevated surface energy, leading to a reduced catalytic activity. Nevertheless, using Ti 3 C 2 T x nanosheets as a robust support can enhance interfacial charge transfer and prevent agglomeration, thereby improving the catalytic activity of the Bi-based catalyst.…”

The distinctive properties of 2D MXenes have garnered significant interest across various fields, including wastewater treatment and photo/electro-catalysis. The integration of inexpensive semiconductor nanostructures with 2D MXenes offers a promising strategy for applications such as wastewater treatment and photoelectrochemical hydrogen production. In this study, we employed an in situ hydrothermal method to immobilize 1D Bi 2 S 3 nanorods and self-reduced metallic bismuth nanoparticles (Bi NPs) onto Ti 3 C 2 T x MXene nanosheets, resulting in the formation of a Bi/Bi 2 S 3 /Ti 3 C 2 T x (0D/1D/2D) composite catalyst, which demonstrates an outstanding efficacy in both the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) and photoelectrochemical hydrogen production. Remarkably, a 4-NP reduction efficiency of 100% was achieved only in 4 min with a reduction rate of 1.14 min −1 , which is outstanding, and it is ∼3.8 times faster than pristine Bi 2 S 3 nanorods (0.3 min −1 ). Furthermore, the photoelectrochemical assessment reveals that the Bi/ Bi 2 S 3 /Ti 3 C 2 T x catalyst displays remarkable hydrogen evolution reaction (HER) efficiency in an alkaline electrolyte. It exhibits a significantly lower overpotential and Tafel slope of 73 mV and 84 mV/dec, respectively, compared to pristine Bi 2 S 3 nanorods, which are found to be 129 mV and 145 mV/dec under light illumination. The superior reduction performance of 4-NP and charge transfer mechanism is further investigated through density functional theory (DFT) calculations, alongside validation using various microscopic and spectroscopic techniques. Interestingly, the DFT analysis revealed modifications in the partial density of states of Bi 2 S 3 within the band gap region due to the successful anchoring of Ti 3 C 2 T x nanosheets and metallic Bi NPs, facilitating efficient charge transport and separation across the local junctions. Ultraviolet photoelectron spectroscopy provided insights into band alignment and interfacial charge transfer across the Bi/Bi 2 S 3 /Ti 3 C 2 T x junction on a microscopic scale. This work is significant for the development of MXene-based hybrid catalysts, and it provides a deeper understanding of the reduction mechanism of organic pollutants and superior charge transport in the hybrid system for photoelectrochemical hydrogen production.
