LPdCl2(amine) Complexes Supported by Terphenyl Phosphanes: Applications in Aryl Amination Reactions
(Royal Society of Chemistry, 2022)
Despite the excellent catalytic properties display by NHC-Pd-PEPPSI complexes in cross-coupling, phosphane analogs have been barely screened. In this work, we report the synthesis and characterization of a series of ...

Impact of Topology Framework of Microporous Solids on Methanol Carbonylation: An Operando DRIFTS-MS Study
(Elsevier, 2023)
Methanol carbonylation was evaluated over heterogeneous catalysts based on Cu-exchanged zeolitic materials with different topology: Cu@MOR, Cu@FER, and Cu@ZSM-5. Despite the similar Si/Al ratios, it is crucial to acknowledge ...

Cobalt Stabilization through Mesopore Confinement on TiO2 Support for Fischer−Tropsch Reaction
(American Chemical Society, 2023)
Cobalt supported on mesostructured TiO2 catalysts has been prepared by a wet-impregnation method. The Co/TiO2 catalytic system showed better catalytic performance after support calcination at 380 °C. Co nanoparticles ...
