Low-cost synthesis of a nanocomposite of MoS₂ and alkali-activated halloysite nanotubes for photocatalytic RhB degradation

Abstract

In this work, a novel nanocomposite of highly-dispersed MoS2 nanosheets supported on alkali-activated halloysite nanotubes (a-HNTs) was fabricated via a simple hydrothermal method. The alkali (5 M NaOH herein) could...

Experimental and ab initio studies on the structural, magnetic, photocatalytic, and antibacterial properties of Cu-doped ZnO nanoparticles

“…8 Yet, its broader bandgap compared to TiO 2 makes ZnO less appealing for photocatalytic applications. [9][10][11][12] To circumvent this problem, researchers have doped ZnO with different metals such as Cr, Sm, Co, Cu, or Ag to improve the photocatalytic activity. 13,14 Among the promising dopants, Cu is preferred due to its advanced attributes such as low toxicity and abundance.…”

Enhanced CO2 Methanation over Ni/Na-HNTs: Effect of Pretreatment with NaOH

“…27 This viewpoint is supported by the findings of Zeng et al, 28 who proposed that NaOH treatment can lead to the generation of hydroxyl groups on the surface of HNTs. Wang et al 29 suggested that NaOH can attack the inert outer surface of HNTs, resulting in abundant surface defects, thereby making the MoS 2 sheets uniformly distributed on the surfaces of HNTs. The as-prepared MoS 2 /a-HNT nanocomposite showed a significantly enhanced photocatalytic efficiency for the degradation of rhodamine B (RhB).…”
