Heterogeneous acid catalysts were prepared by sulfonation of nanoporous carbons (NPCs). The NPCs were produced by pyrolysis of resorcinol-formaldehyde nanoporous resins (NPRs). The NPRs were synthesized as wet gels by ...

Sulfonated porous carbons (PCs-SO3H) are prepared by the sol-gel reaction of resorcinol and formaldehyde. The porosity is maintained during drying using a cationic polyelectrolyte as pore stabilizer. It was found that ...

Electrospun submicrometer-sized poly(e-caprolactone) (PCL) meshes and nanosized multiwalled carbon nanotubes (MWCNTs) were used as a template for preparing porous and interconnected inorganic organic hybrid materials ...

Hydrogen is considered to be a clean, economical and safe renewable energy source that would be ideal to replace fossil fuels, because it is light, highly abundant and its oxidation product (water) is environmentally benign. ...

La presente tesis desarrolla una nueva metodología de preparación de monolitos de carbono a partir de diversos materiales carbonosos abarcando desde carbones minerales hasta materiales diseñados con características específicas ...

El furfural y ácido levulínico (AL) son compuestos derivados de biomasa de alto interés para la industria ya que permite la obtención de múltiples productos. En este trabajo se evaluó su obtención en un proceso de dos ...

A sample of expanded polystyrene (EPS) was isolated from a whole solid waste sample as raw material, for the synthesis of the polyamino styrene (PSNH2) in a two steps process. Initially, it was carried out the nitration ...

Due to the anthropogenic activities that promote the contamination of the water resource, including the industrial processes in which the dyes intervene, day by day alternatives for its treatment are looked for. The use ...
