    • openAccess   Introducing Structural Diversity: Fe-2(MoO4)(3) Immobilized in Chitosan Films as an Efficient Catalyst for the Selective Oxidation of Sulfides to Sulfones 

      Ordonho Líbero, Laura; Ribeiro, Lara Kelly; Granone, Luis Ignacio; Churio, Maria Sandra; Souza, Josiane C.; Mastelaro, Valmor Roberto; Andres, Juan; Longo, Elson; Mascaro, Lucia Wiley (2023-03-27)
      This work reports how the immobilization of Fe2(MoO4)3 in chitosan films affects the oxidation reaction of sulfide derivatives to sulfates in the dark, resulting in good yields and excellent selectivity. As demonstrated, ...

    • openAccess   Manganese Defective Clustering: Influence on the Spectroscopic Features of Ceria-Based Nanomaterials 

      Amaral, D.C.; Rosa Rocha, Leandro Silva; Granone, Luis Ignacio; Lage, M.M.; Churio, Maria Sandra; Sanchez, M. D.; Longo, Elson; Nascimento, H. M. S.; Assis, Marcelo de; Moura, F.; Ponce, M. A. American Chemical Society (2023-07-21)
      The influence of manganese modification on the spectroscopic features of manganese-doped CeO2 systems synthesized by the microwave-assisted hydrothermal route and their correlation with the presence of O defective structures ...

    • openAccess   Towards an efficient selective oxidation of sulfides to sulfones by NiWO4 and α-Ag2WO4 

      Assis, Marcelo de; Gouveia, Amanda; Ribeiro, Lara Kelly; Ponce, Miguel Adolfo; Churio, Maria Sandra; Oliveira, Osvaldo N.; Mascaro, Lucia; Longo, Elson; Llusar, Rosa; Guillamón, Eva; Andres, Juan Elsevier (2023-02-25)
      Chemoselective oxidation of sulfides to sulfones under mild conditions is relevant for industry, but challenging owing to the need to establish catalysis mechanisms and optimize several experimental parameters. Herein, we ...

    • openAccess   Tuning the morphology to enhance the catalytic activity of α-Ag2WO4 through V-doping 

      Lima Patrocinio, Katiana; Santos, Jeziel Rodrigues; Granone, Luis Ignacio; Ponce, Miguel Adolfo; Churio, Maria Sandra; Ribeiro, Lara Kelly; Daldin Teodoro, Marcio; Llusar, Rosa; Andres, Juan; Longo, Elson; Assis, Marcelo de Royal Society of Chemistry (2023-09-30)
      Here, we present the synthesis of a highly efficient V-doped α-Ag2WO4 catalyst for the oxidation of sulfides to sulfones, exhibiting a high degree of tolerance towards various sensitive functional groups. Remarkably, the ...
