Hydrogen Storage and Materials

Abstract Hydrogen adsorption on Pd-based nanoalloys was investigated for truncated-octahedral Pd $$_{32}$$ Ir $$_N$$ Rh $$_{6-N}$$ (N=0,3,6) nanoclusters using a hierarchical computational approach combining Gupta-based global optimization, molecular dynamics, local atomic pressure analysis, and spin-polarized DFT+ U…

Zeolitic imidazolate framework-8 (ZIF-8), a type of metal–organic framework (MOF), is considered a promising material for cryogenic hydrogen storage due to its high surface area, well-defined microporous structure, and strong thermal stability. In this study, pure ZIF-8 and several composite materials containing iron…

The hydrogen storage performance of LaNi₅ was systematically investigated under different pressure conditions. Hydrogen absorption experiments using LaNi₅ were conducted at hydrogen pressures of 10, 20, and 30 bar. Structural and morphological characterizations were carried out using Raman spectroscopy, XRD, SEM, and…

Abstract Solid-state hydrogen storage is a critical challenge for the practical use of hydrogen-based energy systems. In this study, La–MoS 2 composite materials containing different MoS 2 contents (1, 2, and 3 wt%) were composized by a ball-milling method to improve the hydrogen storage performance of lanthanum. Stru…

In this study, Co–Fe–B catalysts were synthesized separately in ethanol and aqueous media under ambient conditions using a chemical reduction–precipitation method for rapid and efficient hydrogen generation from sodium borohydride (NaBH 4 ) hydrolysis. The structural and morphological properties of the synthesized cat…

Bu çalışma, sera gazı emisyonlarının azaltılmasına katkı sağlayan çevreci bir enerji taşıyıcısı olan hidrojenin, sodyum borhidrür (NaBH4) çözeltisinin hidrolizi yoluyla elde edilmesini amaçlamaktadır. Bu doğrultuda, karabaş otu ekstraktı destekli Co–Zn–B nanomalzemeleri, yeşil sentez ve kimyasal indirgeme tekniklerini…

Artan enerji ihtiyacı, fosil yakıtların sınırlı olması ve çevresel kaygılar, alternatif enerji kaynaklarına yönelimi hızlandırmıştır. Bu bağlamda hidrojen, yüksek enerji yoğunluğu ve çevre dostu özellikleri ile öne çıkan bir enerji taşıyıcısıdır. Bu çalışmada, hidrojen üretimi için sodyum borhidrür (NaBH₄) kullanılmış…
