We report the application of a solid lanthanum–ceria–zinc catalyst in the catalytic regeneration of diesel particulate filters (DPF) in diesel engines. We synthesized a CeO2–ZnO–La2O3 (Ce–Zn–La) mixed oxide by a lactic acid-mediated sol

Species of the Byrsonima genus are widely used in Brazil, especially for the treatment of gastrointestinal disorders. However, species from the Amazonian region are still poorly studied. Thus, we studied the antioxidant, antinociceptive, and anti-inf

Cordierite honeycomb monoliths coated with ceria-copper catalyst were synthesized, characterized, and used in catalytic soot oxidation. First, Ce 0.6 Cu 0.4 O 2 was obtained by the sol–gel method and deposited on cordierite. The resulting material

In this study, we propose that ceria-based catalysts are capable to diminish the temperature at which the soot combustion occurs to values within the operation range of diesel engines exhaust gases. We investigated how the addition of 5 wt.% silver n

We employed modified substrates as outer heterogeneous catalysts to reduce the soot originating from the incomplete diesel combustion. Here, we proposed that ceria (CeO 2 )-based catalysts could lower the temperature at which soot combustion occurred

We used ceria-based catalysts to reduce the soot combustion temperature from 600 °C to values included in the operation range of diesel exhausts (270–400 °C). We synthesized CeO2–ZrO2 by the sol–gel method and effectively deposited the mixed
