Small, Год журнала: 2024, Номер unknown

Опубликована: Май 15, 2024

Abstract In the field of photocatalytic CO 2 reduction, quantum dot (QD) assemblies have emerged as promising candidate photocatalysts due to their superior light absorption and better substrate adsorption. However, poor contacts within QD lead low interfacial charge transfer efficiency, making suffer from unsatisfactory performance. Herein, a novel approach is presented involving construction strongly fused CdS (CdS gel) for reduction. The gel demonstrates outstanding performance methanation, achieving CH 4 generation rate ≈296 µmol g −1 h , with selectivity surpassing 76% an apparent yield (AQY) 1.4%. Further investigations reveal that robust fusion in these QDs not only boosts ability absorb visible but also significantly promotes separation. present work paves way utilizing realizing efficient reduction highlights critical role engineering photocatalysts.

Abstract Halide perovskites exhibit outstanding optoelectronic properties, which make them an ideal choice for photocatalytic CO 2 reduction and benzyl alcohol (BA) oxidation. Nevertheless, the simultaneous realization of above redox coupling reactions on halide remains a great challenge, as it requires distinct catalytic sites different target reactions. Herein, Cs AgBiCl 6 (CABC) are regulated by doping Fe efficient BA The Fe‐doped CABC (Fe: CABC) exhibits enhanced visible‐light response effective charge separation. Experimental results theoretical calculations reveal synergistic interplay between Bi sites, where have lower activation energies toward Further investigations demonstrate that electrons holes prefer to accumulate at site under light irradiation, respectively, creates favorable conditions facilitating resultant Fe: achieves high performance (18.5 µmol g −1 h ) BD (1.1 mmol generation, surpasses most state‐of‐the‐art photocatalysts. This work demonstrates facile strategy regulating reactions, will pave new way designing photocatalysis.

Nitrogen Configuration Effects on Charge Carrier Dynamics in CsPbBr₃/Carbon Dots S-Scheme Heterojunction for Photocatalytic CO₂ Reduction

The Journal of Physical Chemistry Letters, Год журнала: 2024, Номер 15(21), С. 5728 - 5737

Опубликована: Май 21, 2024

Nitrogen-doped carbon dots (NCDs) featuring primary pyrrolic N and pyridinic dominated configurations were prepared using hydrothermal (H-NCDs) microwave (M-NCDs) methods, respectively. These H-NCDs M-NCDs subsequently applied to decorate CsPbBr3 nanocrystals (CPB NCs) individually, a ligand-assisted reprecipitation process. Both CPB/M-NCDs CPB/H-NCDs nanoheterostructures (NHSs) exhibited S-scheme charge transfer behavior, which enhanced their performance in photocatalytic CO2 reduction selectivity of CO2-to-CH4 conversion, compared pristine CPB NCs. The presence configuration at the heterojunction facilitated efficient transfer, leading remarkable 43-fold increase photoactivity. In contrast, showed only modest 3-fold enhancement photoactivity, was attributed electron trapping by heterojunction. study offers crucial insights into carrier dynamics within perovskite/carbon NHSs molecular level advance understanding solar fuel generation.

Finding appropriate photocatalysts for solar‐driven water (H 2 O) splitting to generate hydrogen ) fuel is a challenging task, particularly when guided by conventional trial‐and‐error experimental methods. Here, density functional theory (DFT) used explore the MXenes photocatalytic properties, an emerging family of two‐dimensional (2D) transition metal carbides and nitrides with chemical formula M n+ 1 X n T x , known be semiconductors having terminations. More than 4,000 MXene structures have been screened, considering different compositional (M, X, structural (stacking termination position) factors, find suitable bandgap in visible region band edges that align water‐splitting half‐reaction potentials. Results from analysis show how, general, = metals group III present most cases promising sizes, C‐MXenes being superior N‐MXenes. From alignment calculations candidate systems larger 1.23 eV, minimum required process, Sc CT Y (T Cl, Br, S, Se) CI are highlighted as adequate photocatalysts.
