A high-speed dispersion homogenization-assisted alkali fusion-hydrothermal method was successfully developed for the preparation of NaA zeolite molecular sieve with excellent adsorption performance for ammonia nitrogen using solid waste fly ash. This study establishes a vital research foundation for the utilization of fly ash and the treatment of ammonia nitrogen wastewater, with great ecological and social benefits.

The electrocatalytic conversion of carbon dioxide (CO2) into valuable chemicals presents a promising strategy for closing the carbon cycle. In this study, we synthesized zinc (Zn) catalysts through hydrothermal methods using either polyvinylpyrrolidone (PVP) or cetyltrimethylammonium bromide (CTAB) as stabilizing agents. These catalysts proved highly efficient in converting CO2 into carbon monoxide (CO).

The effect of additions of two series of SnO2 nanoparticles synthesized using two different methods on crystal structure and superconductivity of Bi1.6Pb0.4Sr2Ca2Cu3O10+δ (BPSCCO) superconductors was investigated. Two series of spherical SnO2 nanoparticles were synthesized independently by using ultra-sonication (US-SnO2) and hydrothermal (HT-SnO2) methods.

In this work, SrFe12O19 samples were synthesized by hydrothermal method. We systematically studied the influence of an alkaline environment (NaOH) with the molar ratio (R) of 2 , 3 and 4 on the structure, magnetic properties of SrFe12O19 particles prepared by hydrothermal method. The relation between morphology, magnetic properties and microwave absorption properties of materials have been investigated.

In this report, SYGO:Eu3+ red phosphor have been successfully synthesized by sol-gel method. The X-ray diffraction results show that the sample has a cubic crystal structure, belonging to the space group Ia3d (230) without any doping. Scanning electron microscopy (FE-SEM) combined with EDS was performed to determine the microstructure and elemental composition of the fabricated phosphor.

CuO nanoparticles were synthesized by alcohol-assisted hydrothermal method at various pH values, using sodium hydroxide as a precursor for pH control. The chemical composition, morphological and structural properties of the obtained CuO nanoparticles were investigated by the Raman and energy-dispersive X-ray spectroscopies, the field-emission scanning electron microscopy, and the X-ray diffraction.

This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

In this work, TiO2-doped carbon aerogel (TiO2/CA) was synthesized from sugarcane bagasse hydrothermal, freezedrying, and carbonization methods. The effects of the calcination temperatures of 400, 500, 600, 700, and 800 oC were also evaluated. The obtained TiO2/CA exhibits an ultralow density (0.021-0.032 g/cm3 ) and porosity of more than 97 %. The asprepared TiO2/CA was applied in photodegradation of methylene blue (MB) with the effects of dose sample and pH were also investigated.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

In this study, we synthesized CuCoFe-LDH bilayer hydroxide catalysts in different Cu:Co:Fe ratios (1:1:1; 1:2:1, and 1:3:2) by hydrothermal method and applied them to activate peroxymonosulfate (PMS) for decomposing levofloxacin. The obtained LDH samples were characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy.

Ebook "MWW-type titanosilicate: Synthesis, structural modification and catalytic applications to green oxidations" provides a comprehensive review of a new generation of selective oxidation titanosilicate catalysts with the MWW topology (Ti-MWW) based on the research achievements of the past 12 years. It gives an overview of the synthesis, structure modification and catalytic properties of Ti-MWW. Ti-MWW can readily be prepared by means of direct hydrothermal synthesis with crystallization-supporting agents, using dual-structure-directing agents and a dry-gel conversion technique.

In this paper, we present the U-Pb age of titanite from different stages of the Sin Quyen deposit used to constrain the timing and origin of such events. The hydrothermal titanites are dated by in situ LA-ICP-MS technique and have UPb ages of 873±12 Ma and 844±12 Ma which indicate two mineralization/hydrothermal events at the same time, respectively.

In this paper, we reported NO2 sensors based on the ZnO nanorods with different sizes fabricated using a simple hydrothermal method without surfactants. The sensors offered the excellent response and sensitivity to NO2 at very low concentrations as low as 100 ppb. The influence of the size of the ZnO nanorods on the NO2 sensing response was focused.
