Photocatalytic water splitting, CO2 reduction, and pollutant degradation have emerged as promising strategies to remedy the existing environmental energy crises. However, grafting of expensive less abundant noble-metal cocatalysts on photocatalyst materials is a mandatory practice achieve enhanced photocatalytic performance owing ability extract electrons efficiently from enable rapid/enhanced catalytic reaction. Hence, developing highly efficient, inexpensive, noble-metal-free composed earth-abundant elements considered noteworthy step toward considering photocatalysis more economical strategy. Recently, MXenes (two-dimensional (2D) transition-metal carbides, nitrides, carbonitrides) shown huge potential alternatives for cocatalysts. several excellent properties, including atomically thin 2D morphology, metallic electrical conductivity, hydrophilic surface, high specific surface area. In addition, they exhibit Gibbs free intermediate H atom adsorption close zero than that commercial Pt-based cocatalyst, Fermi level position above H2 generation potential, an capture activate molecules. Therefore, there growing interest in MXene-based various events. this review, we focus recent advances synthesis with 0D morphologies, stability MXenes, photocatalysts evolution, degradation. The challenges possible future directions enhance are also discussed.

Plasmonic Active “Hot Spots”‐Confined Photocatalytic CO₂ Reduction with High Selectivity for CH₄ Production

Advanced Materials, Год журнала: 2022, Номер 34(14)

Опубликована: Фев. 3, 2022

Plasmonic nanostructures have tremendous potential to be applied in photocatalytic CO2 reduction, since their localized surface plasmon resonance can collect low-energy-photons derive energetic "hot electrons" for reducing the activation-barrier. However, hot electron-driven reduction is usually limited by poor efficiency and low selectivity producing kinetically unfavorable hydrocarbons. Here, a new idea of plasmonic active spot"-confined photocatalysis proposed overcome this drawback. W18 O49 nanowires on outer Au nanoparticles-embedded TiO2 electrospun nanofibers are assembled obtain lots Au/TiO2 /W18 sandwich-like substructures formed heterostructure. The short distance (< 10 nm) between adjacent induce an intense plasmon-coupling form spots" substructures. These capable not only gathering incident light enhance generation migration, but also capturing protons CO through dual-hetero-active-sites (Au-O-Ti W-O-Ti) at interface, as evidenced systematic experiments simulation analyses. Thus, during 43± 2 °C, these enriched well-designed heterostructure synergistically confine hot-electron, proton, intermediates resulting CH4 production-rates ≈35.55 ≈2.57 µmol g-1 h-1 , respectively, -product ≈93.3%.

Sluggish charge kinetics and low CO2 affinity seriously limit the photocatalytic reduction reaction. Herein, simultaneous promotion of transfer activation over two-dimensional (2D) WO3 nanosheets is achieved by coupling surface C-doping oxygen vacancy. The surface-doped C atoms reconstruct atomic extracting lattice to generate intimate vacancy (C–OV coordination) as active center, which facilitates adsorption/activation, thus inducing formation *CO2 species. As a delivery channel, an exclusive W–O–C covalent bond formed C–OV coordination could enhance electron transfer. result, as-designed catalyst exhibits 85.8% selectivity for photoreduction CO under gas–solid phase reaction, with yield rate 23.2 μmol g–1 h–1 stable long-term reactivity 24 h.
