NiSe2 Nanoparticles Supported on Halloysite Sheets as an Efficient Electrocatalyst toward Alkaline Oxygen Evolution Reaction

“…Between the large numbers of materials studied, naturally abundant clay minerals with unique nanostructures, low cost, and stable physicochemical properties are believed to provide powerful candidates for electrocatalytic water splitting. , Halloysite is a widespread and inexpensive alumino-silicate clay mineral that can adopt different morphologies, including spheroidal, fibers, onions, platy shape, prismatic, and short tubular structures . Halloysite has been widely studied for various applications due to its significant properties such as high surface/volume ratio, tunable surface chemistry, rich active sites, good thermal stability, and high mechanical properties. , Halloysite has been proven as a promising material for the formation of composites for environmental applications, resulting in a pronounced improvement in the performance of the final composite, benefitting from the synergism between the two components.…”

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

“…For example, Peng et al synthesized MoS 2 /HNT in which MoS 2 nanosheets only dispersed in the lumen of HNTs and the outer surface of HNTs was bare. 21 Therefore, an appropriate modification on HNTs would raise the availability of HNTs and optimize the synergistic effect between HNTs and active compounds as well.…”

CdS Quantum Dots in Hierarchical Mesoporous Silica Templated on Clay Nanotubes: Implications for Photocatalytic Hydrogen Production

“…To develop sustainable photocatalytic technologies, it is important to produce economically feasible and efficient photocatalysts. The morphology of supports is one of the vital factors to be considered for the design of composites such as photocatalysts or electrocatalysts and therefore the morphological effect of supports on the catalytic activity is necessary to be unraveled . Inorganic supports play a key role in building up nanostructured catalysts capable of industrial application .…”

“…Inorganic supports play a key role in building up nanostructured catalysts capable of industrial application . Due to the availability of clay minerals, as well as opportunities for their chemical modification, these materials have been studied as prospective supports for photocatalytic nanoparticles. − TiO 2 , g-C 3 N 4 , ZnO, CdS, and MoS 2 are among the most efficient semiconductors and have been supported on clay minerals. ,, Tubular clays such as halloysite are characterized by better catalytic activity in photocatalytic reactions, compared to platy ones due to the higher dispersibility in reaction media, higher surface area, and additional possibility of placing active sites inside clay nanotubes. , To achieve better photocatalytic results, modification of clay tubes was performed prior to the stabilization of nanoparticles. − Grafting of aminosilanes and organic ligands on the surface of clays led to efficient photocatalysts. ,, The tailored design of new supports and optimization of the composition and the structure of catalysts are some strategies applied for enhancing the photocatalytic efficiency . However, this approach has not been fully transferred to the nanoarchitectonics of photocatalytic systems, yet.…”
