Decoration of titania nanofibres with anatase nanoparticles as efficient photocatalysts for decomposing pesticides and phenols [PDF]

, 2012
Using a series of partial phase transitions, an effective photocatalyst with fibril morphology was prepared. The catalytic activities of these materials were tested against phenol and herbicide in water. Both H-titanate and TiO2-(B) fibres decorated with

Controlling the Synthesis Conditions for Tuning the Properties of Hydrotalcite-Like Materials at the Nano Scale

ChemEngineering, 2018
Three series of layered double hydroxides (LDH) with a hydrotalcite-like structure and composition corresponding to [Mg4Al2(OH)12(CO3)]·3H2O have been prepared from a common batch by applying three different aging procedures, namely, stirring at room ...

Hydrothermal pre-treatment of rapeseed straw

Bioresource Technology, 2010
As a first step for ethanol production from alternative raw materials, rapeseed straw was studied for fermentable sugar production. Liquid hot water was used as a pre-treatment method and the influence of the main pre-treatment variables was assessed. Experimental design and response surface methodology were applied using pre-treatment temperature and ...

Hydrothermal treatment of wollastonite

Journal of the Mineralogical Society of Japan, 1981
In order to investigate the genesis of stevensite experimentally, naturally occurring wollastonite was treated hydrothermally with basic magnesium carbonate for various Mg (in basic magnesium carbonate) /Si (in wollastonite) molecular ratios ranging from 0.1 to 1.5. The products were examined by means of X-ray diffraction, thermal analysis and scanning

INFLUENCE OF DESILICATION CONDITIONS ON THE SYNTHESIS OF HIERARCHICAL ZEOLITE Y

Revista Politécnica, 2019
Hierarchical zeolites were synthesized by two methodologies, following desilication procedures of commercial zeolites. Starting from USY zeolite (Zeolyst CBV720, Si/Al=15), the effect of the amount of CTAB in the desilication media and the hydrothermal ...

Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Hydrothermal treatment of pectolite

Journal of the Mineralogical Society of Japan, 1979
In order to investigate the genesis of stevensite and “hydrated talc” experimentally, naturally occurring pectolite was treated hydrothermally with 1, 2 and 4 normal magnesium chloride solution and with basic magnesium carbonate for various Mg (in basic magnesium carbonate)/Si (in pectolite) molecular ratios ranging from 0.1 to 1.5.

Perfluorosulfonic Acid Membranes Modified with Polyaniline and Hydrothermally Treated for Potentiometric Sensor Arrays for the Analysis of Combination Drugs

Membranes, 2023
A novel potentiometric multisensory system for the analysis of sulfamethoxazole and trimethoprim combination drugs was developed. The potentiometric sensors (Donnan potential (DP) was used as an analytical signal) with an inner reference solution were ...
