Novel electrospun PVA/Fe-MOF nanofibres as a super adsorbing material of lead ions in aqueous solution

Shooto N.D., Dikio E.D., Sikhwivhilu L., Wankasi D., VUT, ZA

In this study electrospun PVA nanofibres were functionalized with Fe-MOFs to synthesise a novel super adsorbing material. The synthesized material was characterized by scanning electron microscope (SEM), Fourier transform infrared (FTIR) and Thermogravimetric analysis (TGA). [...]

Graphene decorated metal nanoclusters as an effective novel catalyst for improving the hydrogen storage behaviour of MgH2

Sterlin Leo Hudson M., Ramesh A., Takahashi K., Central University of Tamil Nadu, IN

Abstract: High volumetric and gravimetric hydrogen density in MgH2 motivates significant research attention over the recent years to make it as a viable hydrogen storage material for fuel cell applications. However, the high thermodynamic stability [...]

Preparation of GO/PVA composite as an adsorbent for the removal of Cr(VI) from water

Singh D.K., Kumar V., Hasan S.H., Indian Institute of Technology (BHU), IN

Cr(VI) is a known toxic heavy metal and has been considered as a priority pollutant in water [1]. The effluent of various industries including electroplating, anodizing baths, leather tanning, steel industry and chromium based catalyst [...]

Adsorption of Cd (II) Ions from Aqueous Solution Using Activated Carbon Prepared from Vitellaria paradoxa Shell

Adebayo G.B., Adekola F.A., Jimoh A.A., Alao F.O., Adegoke H.I., University of Ilorin, NG

Activated carbon prepared from vitellaria paradoxa shell using ortho-phosphoric acid as activating agent was used for the removal of Cd (II) ions from aqueous solution. The adsorbent sample was characterized by some physicochemical and spectroscopic [...]

Effect of Big-Cube Zr2Ni on the Absorption and Desorption Kinetics of Nanocrystalline MgH2 Powders
