Flower-like NiAl-LDH/BiVO₄ Z-scheme photocatalysts for sunlight-driven degradation of azo dye: performance and mechanistic insights.

ABSTRACT: Layered double hydroxide (LDH)-based materials have garnered significant attention as versatile photocatalysts for environmental remediation, particularly for the abatement of dye-laden wastewater, owing to their structural tunability, chemical robustness, and facile synthetic routes. In this context, a series of NiAl-LDH/BiVO₄ (NAL/BV) Z-scheme heterojunction nanocomposites were constructed by loading 5-15% (wt%) of BiVO₄ onto LDH via an ex situ fabrication method, and evaluated for photocatalytic degradation of Congo red (CR), a typical azo dye, under solar irradiation. The structural, morphological, and optical attributes of the nanocomposites were meticulously elucidated through comprehensive analyses, including XPS, FTIR, PL, UV-DRS, FESEM, HRTEM, a
