Аннотация (краткое описание)
Cellulose-based composite materials have attracted increasing interest among scientists working on developing energy-storage materials with unique properties. In the present study, an aerogel was synthesized from sunflower seed husk (SFH) to form microcrystalline cellulose (MCC), the hydrogen (H2) sorption potential of which was then investigated. The effect of MCC concentration on the nitrogen sorption capacity of the aerogel samples obtained was assessed based on comparison with other like materials. As per the results of BET analysis, the aerogel with an MCC concentration of 3% was determined to be microporous, with a specific surface area of 3000 cm2/g, average pore diameter of 29.7 nm, total pore volume of 0.44 cm3/g, density of 166 kg/m3, and porosity of 95%. It was found that at a temperature of 77 K and up to 1 bar, MCC3/polyacrylamide (PAm) aerogel can sorb up to 0.8% hydrogen. Additionally, the results of SEM analysis revealed a microporous surface morphology, while FTIR analysis showed that the hydroxy groups in the MCC molecule and the amino groups in the PAm molecule form hydrogen bonds with each other. The results of the research indicate that such an aerogel has potential for use as a material for H2 storage, and appears to be more ecologically friendly than the metal hydrides used in many H2 fuel cells and storage containers, the end-of-life processing of which remains a relatively unexplored issue. Generally, cellulose is considered to be a highly desirable material from both ecological and economic perspectives. © The Author(s), under exclusive licence to Springer Nature B.V. 2025.DOI

Практическое значение
This study demonstrates the potential of cellulose-based aerogels derived from sunflower husk waste as environmentally friendly materials for hydrogen storage applications. The developed MCC/polyacrylamide aerogel combines high porosity, large surface area, and effective hydrogen sorption capacity, providing a sustainable alternative to conventional metal-based hydrogen storage materials while promoting the valorization of agricultural wasteКвартиль
