Özet

A vast study on H-capture by LiRb (SnO2-SiO2), LiCs(SnO2-SiO2), NaRb(SnO2-SiO2), NaCs(SnO2-SiO2), KRb(SnO2-SiO2), KCs(SnO2-SiO2), was carried out including using DFT computations at the CAM–B3LYP–D3/6–311+G (d,p) level of theory. The hypothesis of the hydrogen adsorption phenomenon was figured out by density distributions of CDD, TDOS/OPDOS, LOL for nanoclusters of LiRb(SnO2-SiO2)–2H2, LiCs(SnO2-SiO2)–2H2, NaRb(SnO2-SiO2)–2H2, NaCs(SnO2-SiO2)–2H2, KRb(SnO2-SiO2)–2H2, KCs(SnO2-SiO2)–2H2. The oscillation in charge density amounts displays that the electronic densities were mainly placed in the edge of adsorbate/adsorbent atoms during the adsorption status. Regarding optimal energy, KRb(SnO2-SiO2), KRb(SnO2-SiO2)–2H2, KCs(SnO2-SiO2), and KCs(SnO2-SiO2)–2H2 heteroclusters have shown more stability than LiRb(SnO2-SiO2), LiRb(SnO2-SiO2)–2H2, LiCs(SnO2-SiO2), LiCs(SnO2-SiO2)–2H2, NaRb(SnO2-SiO2), NaRb(SnO2-SiO2)–2H2, NaCs(SnO2-SiO2), NaCs(SnO2-SiO2)–2H2 heteroclusters. In this research, hydrogen energy sources on functionalized 2D materials by metals have been shown as promising alternatives for clean energy systems. In a particular way, we have demonstrated here that (SnO2-SiO2) weakly adsorbs H2. At the same time, the Li/Na/K decoration significantly enhances the H2 interaction, accommodating to H2 molecules by a stronger physisorption.
