Abstract: High Resolution Image Download MS PowerPoint Slide MBene is a type of 2D metal boride compound that has drawn broad attention in the past decade. In this study, MoAlB was partially etched into a mixture of MoBene (Mo-based MBene) and Mo 2 AlB 2 . The performance in metal adsorption of the product was investigated. The large surface area (40 times higher than that of the MoAlB precursor) and −OH-functionalized surface enable MoBene/Mo 2 AlB 2 to have excellent adsorption efficiency and capacity for Cu 2+ and Pb 2+ ions. An adsorption of 89.1 mg/g (93.7% of 1.5 mM CuCl 2 solution) and 121.2 mg/g (39.2% of 1.5 mM PbCl 2 solution) for Cu 2+ and Pb 2+, respectively, was observed after 15 min of contact time. The effects of the pH, contact time, adsorbent load, and initial solution concentration on adsorption capacity were investigated. The maximum adsorption capacities of Cu 2+ and Pb 2+ were 233.4 and 308.6 mg/g, respectively. Target metals can be observed on the adsorbent surface under SEM. The maximum adsorption of Cu 2+ and Pb 2+ is 140 times and 3 times higher than that of commercial activated carbon, showcasing the ability of MoBene/Mo 2 AlB 2 to remove heavy metals from aqueous solutions.
