Bio-oil production from hydrogenation liquefaction of rice straw over metal (Ni, Co, Cu)-modified CeO2 catalysts
This paper describes catalytic hydrogenation liquefaction of rice straw over metal (Ni, Co, and Cu)-modified CeO2 catalysts for bio-oil production. The results show that the highest rice straw conversion (89.08%) and bio-oil yield (66.7%) were obtained over Ni/CeO2 catalyst. The bio-oil contains mainly phenols, high-value-added, and widely used chemicals. Furthermore, metal-modified CeO2 catalys...

Catalytic hydroliquefaction of rice straw for bio-oil production using Ni/CeO2 catalysts
A series of Ni/CeO2 catalysts were synthesized via a simple one-pot hydrothermal method and characterized by XRD, SEM, TEM, EDX, EDX mapping, Raman, H-2-TPR, BET, XPS, TGA and ICP-MS. Their catalytic performances were systematically evaluated in hydroliquefaction of rice
straw. The impact of reaction temperature, reaction time, H-2 pressure and Ni/Ce molar ratios on product yields and distrib...

Promoting Effect of Boron on the Stability and Activity of Ni/Mo2C Catalyst for Hydrogenation of Alkali Lignin
Different amount of boron-modified Ni/Mo2C were synthesized, characterized and tested during the hydrogenation of alkali lignin, to evaluate the effect of boron on the Ni promoted behavior. xB-Ni/Mo2C (x =0.5, 1, 3, 5) is found to enhance the lignin conversion and bio-oil yield at the same time, and the highest bio-oil yield was obtained with 1B-Ni/Mo2C (63.8%), under the optimum reaction condit...

40. Synthesis of graphene/Ni-Al layered double hydroxide nanowires and their application as electrode material for supercapacitors
Graphene oxide (GO) as a template for the morphology controllable synthesis of inorganic particles has recently attracted enormous attention. In this study, we report the synthesis of graphene/Ni-Al layered double hydroxide (LDH) nanowires by using GO and adjusting the loading of urea in hydrothermal reactions. Transmission electron microscopy observation demonstrates that the graphene/Ni-Al LDH n...

【Electrochimica Acta】Hydrothermal Synthesis Of Ni(OH)2 Nanoflakes On 3D Graphene Foam For High-Performance Supercapacitors
Ni(OH)2 nanoflakes were successfully synthesized with a facile hydrothermal method on 3D (three-dimensional) graphene grown by atmospheric pressure chemical vapor deposition (APCVD). The hydrothermal temperature and time were optimized to improve the performance of the composite as a binder-free supercapacitor electrode. The Ni(OH)2/3D graphene composite synthesized at 180 °C for 3 h shows high...

Electrodeposition of Ni-Co-S nanosheet arrays on N-doped porous carbon nanofibers for flexible asymmetric supercapacitors
ABSTRACT: In this work, a novel flexible electrode material for supercapacitor is prepared by electrodeposition of Ni-Co-S interconnected nanosheet arrays on N-doped hierarchical porous carbon nanofibers (Ni-Co-S@N-pCNFs). The electrode exhibits a remarkable specific capacitance of 520.2 F·g-1 at the current density of 0.2 A·g-1 and 670 F·g-1 at 2mV·s-1. The activated...

Pt-Ni bimetallic composite nanocatalysts prepared by using multi-walled carbon nanotubes as reductants for ethanol oxidation reaction
The multi-walled carbon nanotubes (MWNTs) are introduced as reductants to prepare bimetallic PtNix composite nanocatalysts via a hydrothermal reaction for the investigation of ethanol oxidation reaction (EOR). The crystal structure and elemental analysis of PtNix/MWNTs nanocatalysts are characterized by X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS), respec...

233. Flexible Hybrid Membranes with Ni(OH)2 Nanoplatelets Vertically Grown on Electrospun Carbon Nanofibers for High-Performance Supercapacitors.
The practical applications of transition metal oxides and hydroxides for supercapacitors are restricted by their intrinsic poor conductivity, large volumetric expansion, and rapid capacitance fading upon cycling, which can be solved by optimizing these materials to nanostructures and confining them within conductive carbonaceous frameworks. In this work, flexible hybrid membranes with ultrathin Ni...
