Abstract

Mesoporous silica is continuously raising in popularity due to its excellent and unique properties, such as customizable pore, surface shape/morphology, large pore volume, and ease of functionalization for wide applications like catalysis, energy, environment, and biomedical areas. In the templated growth synthesis, a template acts as a mesostructure-directing agent to produce hollow porous structures in silica frameworks. Templates can be divided into "hard" and "soft" templates. While soft templates are typically in a fluid-like condition and hard templates are typically solid-state materials with specific morphology and structure. In this minireview, we summarize the synthesis method of mesoporous silica with a soft-hard template approach (template-assisted method).

Abstract

The practical technique for membrane modification is dip coating. This study coats a PVDF hollow fiber membrane-based composite with a coating of zeolite. The composite is made of a polyvinylidene fluoride (PVDF) membrane. During water filtering, the separation capabilities and propensities of composite membranes for organic impurities were examined. Fourier-transform infrared spectroscopy analysis of the findings demonstrated that the Zeolite coating was successfully deposited on the PVDF membrane. The flux recovery ratio increases from 69% to 80% while the relative flux drop decreases from 63% to 50%. A composite PVDF membrane dip-coating of Zeolite with a GA and H2SO4 ratio of 1:2 is needed to remove about 75% of humic compounds from effluent. The results of this study show that the addition of Zeolite with a GA and H2SO4 layer can greatly improve the hydrophilicity, selectivity, and anti-organic fouling of the PVDF hollow fiber membrane.

Abstract

Photodegradation of organic pollutants depends significantly on the structure of metal oxide-based semiconductor photocatalysts. ZnO/ZSM-5 has shown the potential to significantly improve its photocatalytic efficiency for removing waterborne pollutants. ZnO/ZSM-5 has been reported to be an active catalyst for degrading methylene blue. These methods commonly involve various catalytic reactions, with the Langmuir-Hinshelwood process being used to describe the reaction kinetics. A kinetic study on the photocatalytic degradation of methylene blue using ZnO/ZSM-5 was conducted under UV-LED lamp irradiation. ZnO/ZSM-5 was characterized using XRD, SEM, and N2 adsorption-desorption, and it was prepared via the impregnation method. The interaction between ZnO/ZSM-5 and methylene blue solutions over a period of 30 to 180 minutes was monitored using a UV-Vis spectrophotometer. The photocatalytic degradation of methylene blue followed first-order rate kinetics. The Langmuir-Hinshelwood (L-H) kinetic analysis revealed that the photocatalytic reaction constant (kc) was 4.207 L.mg-1. menit-1, and the Langmuir-Hinshelwood constant (K) was 261.509 L.mg-1.

Abstract

Mesoporous silica is a versatile material characterized by its highly ordered nanoporous structure with pore diameters ranging from 2 to 50 nanometers. This unique structure provides a large surface area and volume, making mesoporous silica an excellent candidate for various applications in adsorption, drug delivery, catalysis, and environmental remediation. Mesoporous silica can be synthesized using commercial or natural silica precursors such as mineral clay and other natural sources. Promising alternative sources of silica for synthesizing mesoporous materials encompass a range of materials, including various clay minerals such as kaolin, rectorite, halloysite, montmorillonite, sepiolite, hectorite, bentonite, talc, muscovite, paragonite, palygorskite, and chlorite. Other natural sources like beach sand, geothermal sludge, and sepiolite also show significant potential for mesoporous material synthesis. However, these sources have not been extensively explored and warrant further investigation in the field. The mesoporous silica from natural sources has been widely used as a catalyst for biofuel production via hydrocracking, catalytic cracking, and deoxygenation reactions
