[EN] Four samples of Zn-hydrotalcite containing different amounts of Co (5, 10, 20, and 30 wt%) have been synthesized and tested in the steam reforming of ethanol. The best results were obtained with the sample containing ...

[EN] Clays are considered great nanoadsorbents for many materials, including textile dyes. The use of these materials for cleaning textile wastewater is well known; however, it is not at all common to find applications for ...

[EN] Textile effluents are among the most polluting industrial effluents in the world. Textile finishing processes, especially dyeing, discharge large quantities of waste that is difficult to treat, such as dyes. By ...

[EN] Catalysts based on gold nanoclusters supported by different materials have been used for the selective semi hydrogenation of phenylacetylene to styrene. The most active species were formed by catalyst thermal activation ...

[EN] By using nanotechnologies it is possible to colour textile substrates with new printing techniques using dyes that have been discarded from non-exhausted dye baths. Hydrotalcite is clay with a high adsorbent capacity ...

[EN] There is growing concern about the health of our planet, which has led to a search for meth-ods to purify and recover the pollutant materials that are released into the environment.Among all industries, the dyeing ...

[EN] Wastewater recovery is one of the most pressing contaminant-related subjects in the textile industry. Many cleaning and recovery techniques have been applied in recent decades, from physical separation to chemical ...
