Abstract Highly porous carbon-based materials with 3-dimensional mesh structure as an adsorbent that have been used extensively in environmental treatment, however, it remains challenging to improve performance and to reduce costs. A novel MoxPy nanoparticles anchored mesh structural biomass carbon (MoxPy/MSBC) was prepared from renewable seaweed and applied as an efficient absorbent for the selective adsorption of dyes. The mesh structure of provides a powerful support for the MoxPynanoparticles and could protect the nanoparticles from being lost. Meanwhile, a better 3D mesh structure obtained endows MSBC a high surface area with a large number of active interaction sites. The MoxPy/MSBC composite exhibits excellent selective adsorption properties and high adsorption capacity for methyl blue (MB) and rose bengal (RB) at distinctive pH and rapid removal rates within 5 min at 298 K. The adsorption kinetics, isotherm and thermodynamics were determined. In addition, the regeneration of the MoxPy/MSBC could be accomplished in only three minutes through a simple method by using the absolute alcohol. Therefore, the simple synthesis, high efficacy, excellent selectivity and regenerability in aqueous medium enable the hybrid nanocomposites as excellent candidates to selective removal processes of dyes.

Molybdenum

See more Molybdenum products. Molybdenum (atomic symbol: Mo, atomic number: 42) is a Block D, Group 6, Period 5 element with an atomic weight of 95.96. Molybdenum Bohr ModelThe number of electrons in each of molybdenum's shells is [2, 8, 18, 13, 1] and its electron configuration is [Kr] 4d5 5s1. The molybdenum atom has a radius of 139 pm and a Van der Waals radius of 209 pm. In its elemental form, molybdenum has a gray metallic appearance. Molybdenum was discovered by Carl Wilhelm in 1778 and first isolated by Peter Jacob Hjelm in 1781. Molybdenum is the 54th most abundant element in the earth's crust. Elemental MolybdenumIt has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum does not occur naturally as a free metal, it is found in various oxidation states in minerals. The primary commercial source of molybdenum is molybdenite, although it is also recovered as a byproduct of copper and tungsten mining. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead.
