Robust Bi-anchoring carbon dot/BiOCl sheet heterojunction photocatalysts toward superior photocatalytic activity

Nanoscale, Год журнала: 2024, Номер 16(26), С. 12670 - 12679

Опубликована: Янв. 1, 2024

BiOCl has attracted much attention due to its robust layered structure, excellent photocatalytic activity and nontoxicity. However, practical application is hindered by narrowband UV photoresponse rapid recombination of photocarriers. Herein, zero-dimensional Bi-anchoring carbon quantum dot (Bi-CD)/two-dimensional heterojunction (Bi-CD/BiOCl) photocatalysts are designed synthesized a facile hydrothermal method. Under 190-1100 nm broadband light irradiation, the optimized Bi-CD/BiOCl sample exhibits superb rhodamine B (RhB) degradation rate nearly 100%, which 2.3 (1.7) times that pristine (CD/BiOCl). Additionally, an RhB up 88.1% even under direct outdoor durability in water solution. Experimental results combined with DFT calculations reveal superior arises from synergetic effects broader absorption incorporation CD, extra hot electron excitation localized surface plasmon resonance (LSPR) effect metallic Bi, enhanced transfer across interface as well existence more oxygen vacancy traps BiOCl. This work gives insights into structure properties provides new strategy for design fabrication high-performance wide spectrum irradiation.

Two-dimensional van der Waals heterostructures have good application prospects in solar energy conversion due to their excellent optoelectronic performance. In this work, the electronic structures of Sc2CF2/Sc2CCl2, Sc2CF2/Sc2CBr2, and Sc2CCl2/Sc2CBr2 heterostructures, as well properties photocatalysis photovoltaics, been comprehensively studied using first-principles method. Firstly, both three thermodynamically dynamically stable are found type-II band alignment with gap values 0.58 eV, 0.78 1.35 eV. Meanwhile, photogenerated carriers Sc2CF2/Sc2CCl2 Sc2CF2/Sc2CBr2 predicated follow direct Z-scheme path, enabling abilities for water splitting. As heterostructure, its photovoltaic efficiency is estimated be 20.78%. Significantly, light absorption coefficients enhanced more than those corresponding monolayers. Moreover, biaxial strains observed considerably tune aforementioned heterostructures. All theoretical results presented work demonstrate potential Sc2CX2/Sc2CY2 (X, Y = F, Cl, Br) photovoltaics.
