Layered Double Hydroxide/Nanocarbon Composites as Heterogeneous Catalysts: A Review
Autor: Didier Tichit, Mayra G. Álvarez
Publikováno v: ChemEngineering, Vol 6, Iss 4, p 45 (2022)
The synthesis and applications of composites based on layered double hydroxides (LDHs) and nanocarbons have recently seen great development. On the one hand, LDHs are versatile 2D compounds that present a plethora of applications, from medicine to en

Synthesis of Chalcone Using LDH/Graphene Nanocatalysts of Different Compositions
Autor: Mayra G. Álvarez, Dana G. Crivoi, Francesc Medina, Didier Tichit
Publikováno v: ChemEngineering, Vol 3, Iss 1, p 29 (2019)
Layered double hydroxides (LDH) or their derived mixed oxides present marked acid-base properties useful in catalysis, but they are generally agglomerated, inducing weak accessibility to the active sites. In the search for improving dispersion and ac

Insights into palladium deactivation during advanced oxidation processes
Autor: Verónica Pinos-Vélez, Oscar Osegueda, Dana Georgiana Crivoi, Jordi Llorca, F. Javier García-García, Mayra G. Álvarez, Francesc Medina, Anton Dafinov
A key step in creating efficient and long-lasting catalysts is understanding their deactivation mechanism(s). On this basis, the behavior of a series of Pd/corundum materials during several hydrogen adsorption/desorption cycles was studied using temp
