GRAFENDAGI STRUKTURAVIY NUQSONLARNING VODOROD ADSORBSIYASIGA TA’SIRI
Ushbu ishda nuqsonli grafenlarda H₂ molekulalarining fizisorbsiyasi reaktiv molekular dinamika usuli bilan o‘rganildi. Nuqsonlar o‘lchami va konsentratsiyasi ortishi qismiy zaryadlar qayta taqsimlanishi hisobiga adsorbsiyani kuchaytirishi, shuningdek, eng yuqori nuqson ulushida gravimetrik zichlik 2,16 wt.%ga yetdi.
В работе методом реактивной молекулярной динамики исследована физическая адсорбция молекул H₂ на дефектном графене. Показано, что увеличение размера и концентрации дефектов усиливает адсорбцию за счёт перераспределения частичных зарядов. При максимальной доле дефектов гравиметрическая плотность достигла 2,16 wt.%.
In this work, the physisorption of H₂ molecules on defective graphene was studied using reactive molecular dynamics. The results show that increasing the size and concentration of defects enhances adsorption through the redistribution of partial charges. At the highest defect fraction, the gravimetric density reached 2.16 wt.%.
