Synthesis of hierarchical structured porous MoS₂/SiO₂ microspheres by ultrasonic spray pyrolysis

Abstract

Hierarchical structure porous MoS 2 /SiO 2 microspheres were prepared by ultrasonic pyrolysis technique. The nanostructured MoS 2 /SiO 2 materials were characterised by scanning electron micrograph (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), high-resolution transmission electron microscope (HRTEM), as well as nitrogen isotherm. The MoS 2 /SiO 2 microspheres, synthesised using polystyrene latex spheres as a template, showed two pore sizes: 5.8 and 68 nm. The micro-, meso-and macropore volume was also calculated. Effect of PSL:SiO 2 ratio on the hierarchical structure was also investigated.

High Frequency Sonoprocessing: A New Field of Cavitation‐Free Acoustic Materials Synthesis, Processing, and Manipulation

“…Bulk crystals: Spray pyrolysis for nanoparticle and nanowire synthesis [70][71][72][73][74] Nanomaterials: Spray pyrolysis for nanocrystallization of molten salts, [75] synthesis of porous transitional metal dichalcogenides and their composites, [ 76,77] and, thin film deposition [78] Polymeric and biological materials: pulmonary drug delivery of aerosols and nanoparticles [ 79,80] SRBW excitation. This is not only due to the increase in the threshold sound intensity [83][84][85][86] needed to trigger these events with increasing frequency, [34,87,88] but also because the greater efficiencies of these systems often necessitate far lower input energies to drive similar mechanical phenomena (e.g., acoustic streaming in liquids) compared to their low-frequency counterparts.…”

A Spray Pyrolysis Approach for the Generation of Patchy Particles

“…In this article, we tested ultrasonic spray pyrolysis as a potential patchy particle generation method. Spray pyrolysis is a simple one-step synthesis process and is widely studied for the generation of various metal and metal oxide particles (Nagashima et al 1987;Gurav et al 1993;Choa et al 2003;Zhong et al 2012;Jian et al 2007;Guo et al 2012;Yao et al 2012). Advantages of ultrasonic spray pyrolysis include the capability of scalable production and adjustable particle size from submicron to several microns.…”

Nickel‐Based Sulfide Materials for Batteries

“…In Mondal et al.’s work, the synthesis of nanostructured hollow NiS submicrometer spheres was completed with an ultrasonic spray pyrolysis (USP) method, which had been previously reported . The solution, which was composed of NiCl 2 ⋅6H 2 O, Na 2 S 2 O 3 ⋅5H 2 O, and colloidal silica, was synthesized with a previously described procedure .…”
