“…[34] These trap these greenhouse gases, which are common outcomes as air pollutants in coal mining and power generation regions. Studies have also demonstrated that graphene nanosheets, graphene oxide (GO), and GO-based materials are effective in removing various pollutants, such as heavy metals, [53][54][55][56] organic pollutants, [57,58] and dyes. [59][60][61] It is well known that the adsorption properties of CMs are mainly determined by their physical pore structures and surface chemical properties.…”

“…Sự suy giảm của giá trị từ độ của mẫu CoFe2O4/GO so với mẫu CoFe2O4 là do có sự xuất hiện của vật liệu GO không từ tính, do đó đã làm thay đổi tổng khối lượng hạt từ trên một đơn vị khối lượng của mẫu. Kết quả của chúng tôi cũng tương đồng với một số kết quả đã công bố [18], [19]. Từ dư (Mr) và lực kháng từ (Hc) của mẫu CoFe2O4 và mẫu CoFe2O4/GO được xác định ở hình 6 và nhận các giá trị tương ứng là 11,6 emu/g; 583 Oe (CoFe2O4) và 7,2 emu/g; 319 Oe (CoFe2O4/GO).…”

“…Molecular simulations have provided invaluable insight on the structural and thermodynamic properties of GO-based nanocomposites [41][42][43] and have managed to shed light on associated mechanisms governing their nanofiltration performance at the molecular level, thus complementing pertinent experimental studies [44][45][46][47] . The adsorption of MB and RB on graphene oxide sheets bearing varying oxidation densities, was examined using molecular dynamics (MD) and Monte Carlo simulations [48][49][50][51][52] . These studies demonstrated a selective adsorption behavior for cationic dyes, mainly due to π-π electron coupling, Van der Waals and electrostatic interactions stemming from GO.…”
