Effect of Biochar Loading on Carbon Nanofibrous Sponge Produced from Biochar and Electrospun Polymer Nanofibers

Numan-Al-Mobin A.M., Maddipudi B., Amar V.S., Shende R.V., Fong H., South Dakota School of Mines and Technology, US

The goal of this study is to process a typical waste product, namely the biochar obtained from the oxygen-limited hydrothermal system of biomass (e.g., corn stover), into the value-added product. Particularly, the 3D carbon nanofibrous [...]

Production of Supercapacitor Carbon Electrodes from Corn-stover Via Facile Thermal Activation

Shell K.M., Maddipudi B.K., Amar V., Thakkar A., Shende R.V., Kumar S., Gupta R.B., Virginia Commonwealth University, US

Use of biomass is an emerging and promising alternative to produce carbon electrodes for supercapacitors. Lignin-rich unhydrolyzed solids (UHS) obtained from alkaline pretreatment and enzymatic hydrolysis of corn stover were valorized into biochar via hydrothermally [...]

HTL Derived Biochar for Supercapacitor Electrodes

Huynh K., Maddipudi B.K., Amar V.S., Houck J.D., Shende R.V., South Dakota School of Mines and Technology, US

In this study, biochar samples were prepared by conversion of biomass feedstock (corn stover) via catalytic hydrothermal liquefaction (HTL) and later used as electrode material in conjunction with sol-gel derived perovskite based mixed (Mn,Ti)-oxides (Mn:Ti [...]

BTMO Catalyzed Hydrothermal Liquefaction of Lignocellulosic Biomass

Amar V., Shende A., Shende R.V., Shende A., Shende R.V., South Dakota School of Mines and Technology, US

Binary transition metal oxide nanoparticles, M1M2Fe2O4 (where M1 or M2 = Ni, Zn, Co), were prepared using a soft templating approach and characterized by powder x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy [...]

Cobalt Doped (Mn,Ti)- Oxides for Supercapacitors

Houck J.D., Amar V.S., Shende R.V., South Dakota School of Mines and Technology, US

In this investigation, a (Mn,Ti)-oxide (Mn:Ti 65:35 wt%) was prepared using surfactant templating assisted sol-gel method. To prepare this nanocomposite, sol-A with Ti precursor and sol-B containing Mn precursor were separately prepared using the required [...]

Hydrogen Generation from Thermochemical Water-Splitting Using Core Shell Ni-Ferrite/Y2O3 Nanoparticles

Amar V.S., Shende R.V., South Dakota School of Mines & Technology, US

During thermochemical water-splitting process for hydrogen generation,ferritenanoparticles undergo significant grain growth that reduces their surface area and affect the porous morphology. Consequently, hydrogen volume generation diminishes with increase in thermochemical cycles. In order to mitigate [...]

Synthesis of Visible light Nanocomposites for H2 Production

Hussein A.M., Shende R.V., South Dakota School of Mines & Technology, US

Visible light active nanocomposites were synthesized by the sol-gel method using non-ionic surfactant as a template. Cr-doped ZrO2-modified coupled ZnO/TiO2 composite was thoroughly characterized for surface area, crystal phase, microstructure, elemental identification and band gap [...]
