Abstract

A system of chemical reactions has been developed which permits the controlled growth of spherical silica particles of uniform size by means of hydrolysis of alkyl silicates and subsequent condensation of silicic acid in alcoholic solutions. Ammonia is used as a morphological catalyst. Particle sizes obtained in suspension range from less than 0.05 μ to 2 μ in diameter.

One-step synthesis of seamlessly contacted non-precious metal cocatalyst modified CdS hollow nanoflowers spheres for photocatalytic hydrogen production
2024, Journal of Materials Science and Technology
This study ingeniously synthesized a novel CdS/NiS hollow nanoflower sphere (HNS) using a one-step method to enhance photocatalytic hydrogen production activity. Compared to conventional preparation methods, this approach features seamlessly interfaced contact that facilitates efficient electron transfer across the interface. The internal hollow structure allows for multiple light reflections, maximizing light absorption, while the exterior shell and inner surfaces simultaneously offer active sites for reactions. The modification with non-noble metal NiS enables the extraction of electrons from CdS to the NiS surface, achieving rapid charge separation. Furthermore, adsorption-free energy calculations reveal that the NiS surface is more conducive to photocatalytic hydrogen generation, providing additional reaction active sites. The results demonstrate a hydrogen production rate of 2.18 mmol g^–1 h^–1 for CdS/NiS HNS, which is 9.48 times greater than that of pristine CdS. This work presents a novel approach for synthesizing seamlessly interfaced contacts between photocatalysts and cocatalysts, offering new insight into efficient one-step synthesis for enhanced photocatalytic performance.
Polyethersulfone/silica composite membrane for desalination
2024, Separation and Purification Technology
In this study, polyethersulfone (PES) membranes for desalination were prepared under different evaporation temperatures. The morphology of the PES membranes was evaluated using scanning electron microscopy, which revealed that at a low evaporation temperature (30 °C and 40 °C) the membranes had a porous structure (the pore size in the range of 11–20 μm), whilst at a high evaporation temperature (50 °C and 60 °C) they had a more dense structure. To improve the desalination efficiency of the PES membrane, silica was generated in-situ in the PES membrane via a sol–gel reaction. The advantage of this technique was to give a good silica dispersion under a mild synthesis condition for the silica compared to the conventional direct mixing method. The effect of the in-situ silica content generated in the PES membrane on its hydrophilicity, mechanical properties, permeate flux, and salt rejection was investigated. The PES membrane prepared under an evaporation temperature at 60 °C with 7 % by weight in-situ silica showed the highest permeate flux (19.55 kg/m²h) and salt rejection (98.9 %). Accordingly, this membrane can be applied to deliver high quality fresh water for daily life.
Luminescence enhancement of Y<inf>2</inf>O<inf>3</inf> thin films based on LSPR effect of Ag nanolayers
2024, Journal of Alloys and Compounds
Based on the local surface plasmon resonance effect of Ag nanolayer, the luminescence enhancement in the visible light range of multilayer thin film has been investigated combined with metal/spacer molecule/photoluminescence material structure. The luminescence enhancement effect of multilayer thin films can be improved by adjusting the spin-coating number of Ag nanolayer and SiO₂ spacer in the multilayer structure. At the same time, the mechanism of enhanced luminescence has been analyzed according to the change in fluorescence lifetime. The effect of the coupling between Ag nanolayer and luminescence layer on the radiative transition rate and fluorescence quantum yield have been discussed. The up-conversion luminescence intensity of the noble metal-modified multilayer thin film can be further improved by combining the multilayer structure with sensitized layer.
Surfactant-free synthesis of mesoporous silica materials (Using tetraetylorthosilicate and oleic acid): Preparation, characterization, and catalytic applications
2024, Journal of Molecular Structure
Mesoporous silica nanoparticles (MSNs), one of the important porous materials, have attracted enormous interest due to their exceptional physical and chemical properties. The present study describes a non-surfactant templating route to mesoporous silica materials with large surface areas (617 m² g⁻¹) and pore volumes (0.6374 cm³ g⁻¹) using the oleic acid template that plays two important roles: as a catalyst for hydrolysis of silicon alkoxide and well-defined three-dimensional arrangement of silica nanospheres (as a natural). The silica was calcined and studied using several techniques such as FE-SEM, FT-IR, XRD, TEM, and BET. Afterward, the surfaces of the mesoporous silica nanoparticles (MSNs) were modified and used as a catalyst for synthesizing pyrazolopyranopyrimidines and pyrido[2,3-d:6,5-d]dipyrimidines.
Double-inverse-opal structured films of a hydrogel framework and mobile inorganic particles
2024, Colloids and Surfaces A: Physicochemical and Engineering Aspects
Double-inverse-opal (DIO) structured assemblies are three-dimensionally ordered porous materials containing core particles inside. In this work, DIO structured films composed of mobile inorganic colloidal particles within an organic polymer gel framework were developed. As the organic backbone, a poly(N-isopropylacrylamide) gel (PNIPAM gel) was employed to enhance the flexibility and processability of the films. A three-dimensional periodic structure of fluorescent-labelled silica core particles in the film was observed with confocal microscopy. Thermally induced volume transitions of the PNIPAM gels were observed, which showed the potential for stimuli-responsive optical materials. By selective etching of the sacrificial shell layers surrounding the core particles, cavities formed around the cores, and they exhibited random Brownian motion inside these pockets in the film. As a new type of organic-inorganic composite material, the proposed DIO structured films possessed unique characteristics originating from the combination of a flexible backbone and mobile cores, applicable to stimuli-responsive photonic devices, reusable catalytic particle assemblies, etc.
Silica-coated gold nanoshells: Surface chemistry, optical properties and stability
2024, Journal of Luminescence
In this study, we present a comprehensive analysis of the optical properties of colloidal gold nanoshells (NSs) with varying thicknesses of the gold layer and an additional silica layer. Our results demonstrate that the spectral position of the localized plasmon resonance in NSs is very sensitive to the above parameters. Furthermore, we observe that the silica coating has a notable impact on the stability of colloidal systems. We supplement our experimental results with theoretical calculations, revealing the relative contributions of the absorption and scattering to the overall extinction as a function of the gold layer thickness. The calculations also provide an insight into the origin of spectral broadening in the case of clustered NSs. Our findings hold significant potential for the design of hybrid materials intended for diverse applications, including refractive-index sensing, metal-enhanced fluorescent emission (MEF), and surface-enhanced Raman scattering (SERS).
