Epoxidation reaction in promising Brazilian biomass: decreased time and catalyst loading to produce renewable monomers
(2021-09-01)
The syntheses of new materials using vegetable oils have increased due to technological interest and low environmental impact. Baru nut provides baru oil, rich in linoleic and oleic fatty acids that can be modified into ...
Propolis green biofilm for the immobilization of carbon nanotubes and metallic ions: Development of redox catalysts
(2021-11-01)
Greener materials have been used in the construction of electrochemical devices, becoming one of the main strands of this scientific development area. Thin films based on natural and renewable sources, such as propolis, ...

First Report About the Use of Micellar Keggin Heteropolyacids as Catalysts in the Green Multicomponent Synthesis of Nifedipine Derivatives
(Springer, 2016-06-24)
Micellar Keggin heteropolyacid catalysts were prepared using hexadecyltrimethylammonium bromide (cetyltrimethylammonium bromide—CTAB), 1-hexadecyl-pyridinium chloride, and Keggin heteropolyacids H3PMo12O40 and H4PMo11VO40 ...
Nanoestructured catalysts for organic reactions: design, synthesis and applications
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-07-29)
The development of more efficient and selective catalysts actively contributes for the design of safer, cleaner and less energy-demanding processes, and, therefore, catalysis is one of the cornerstones of green chemistry. ...
Keggin heteropolyacids Mo-based as catalysts in the green and selective oxidation of diphenyl sulfide
(Elsevier, 2013-03)
Heteropolyacids are used as redox catalysts due to their bifunctional properties. Some advantages over conventional catalysts, such as selectivity, easy isolation and reuse, are worth noting. In homogeneous conditions their ...
Superficial properties of activated carbon fiber catalysts produced by green synthesis and their application in water purification
(Springer Heidelberg, 2020-07)
Catalysts of Pd-In supported on activated carbon fiber were synthesized, characterized, and evaluated for the removal of nitrogen oxyanions from water. The work was carried out aiming the development of a green synthesis ...
