Application


  • Palladium (0) nanoparticles distributed on lanthanum (III) oxide as an effective catalyst for the methanolysis of hydrazine-borane to produce hydrogen.: The study presents a novel catalyst combining Pd(0) nanoparticles with La(III) oxide for efficient hydrogen production through methanolysis of hydrazine-borane (Ruzgar et al., 2024).

  • Influence of Lanthanum Precursor on the Activity of Nickel Catalysts in the Mixed-Methane Reforming Process.: This paper investigates how different lanthanum precursors affect the performance of nickel catalysts in mixed-methane reforming, highlighting La(III) oxide′s role in catalytic processes (Zakrzewski et al., 2023).
