“…The inverse Spin Hall voltage across the Pd layer can be observed during driven ferromagnetic resonance (FMR) in the Co layer [2]. A strong spin-pumping effect [3] across the interface underlies the strong inverse Spin Hall Effect (iSHE). Unique for palladium is its affinity to hydrogen gas (H 2 ) at room temperature and normal atmospheric pressure.…”

The influence of hydrogen gas absorption by the Pd layer of bi-layered films containing Pd and Co layers on the inverse Spin Hall Effect (iSHE) in the material is measured. iSHE is driven by ferromagnetic resonance in the cobalt layer. In these conditions, the iSHE is seen as a d.c. voltage across the Pd layer. In the presence of hydrogen gas the iSHE peak shifts downwards in the applied field together with the ferromagnetic resonance absorption peak for the material. In parallel, an increase in the iSHE peak height and in its width is observed. Our analysis suggests that these observations can potentially be explained as a reduction in the spin Hall angle for the Palladium layer in the presence of hydrogen gas.

“…The reaction time is a crucial factor in determining reaction kinetics and important parameters. In most of nano‐catalyzed transesterification reactions, the biodiesel production becomes less efficient or economical after a certain time period 92–98. The transesterification of fatty acids into biodiesel using inorganic metal oxides leads to higher conversion rates into their respective alcoholic esters.…”

“…The nanocatalysts can be easily recovered and reused in subsequent cycles without losing their catalytic reactivity. As a result, the majority of metal‐based nanocatalysts are environmentally friendly for heterogeneous catalysis in the biodiesel production 92–96, 99, 100. The stirring speed of transesterification reaction enhances the percentage yield of biodiesel.…”

Advances in Metal Oxide‐based Nanocatalysts for Biodiesel Production: A Review

et al. 2023

The demand for renewable fuels has risen as a result of increasing human population, urbanization, industrialization, and transport systems. Biodiesel production using metal oxide-based heterogeneous catalysts is an efficient, sustainable, and environmentally friendly approach. Because of their recovery, reusability, and consistency, heterogeneous catalysts may be preferable to homogeneous catalysts. Since the last few decades, the metal oxides of alkali earth and transition metals and their composite materials have been used as nanocatalysts in the production of biodiesel fuel. Utilization of inorganic metal oxide nanoparticles (MONPs) and their composite materials in producing biodiesel has gained increased attention because of their advanced physical and chemical characteristics. In this review, the applicability of metal oxides and their nanocomposite-based catalysts in biodiesel production, transesterification reactions with nanocatalytic systems, and the important parameters that affect these reactions are discussed.
