Influence of Weight Fraction on the Average Crystallite Size of Hybrid ZnO/Al2O3 Supported Bio-Waste Activated Carbon Composites

Onuoha David Chikaorama*, Egbe Evudiovo Apha Peter, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka

Due to the inherent high surface energy and the multifaceted interaction between them and the matrix interface, metal  nanoparticles tend to coalesce in the absence of repulsive forces provided by a capping agent. It is therefore imperative  to provide a support system that will moderate the spatial behaviour of the partic...

Evaluation of the Effects of Weight Fraction on the Average Crystallite Size of ZnO Supported Bio-Waste Activated Carbon Composites

Onuoha David Chikaorama*, Egbe Evudiovo Apha Peter, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka

Metal nanoparticles are known to possess outstanding mechanical properties, relative to their bulk materials. However, due to large surface energy, nanoparticles tend to coalesce to each other, forming bulk particles and eventually deteriorate in quality. It is therefore, essential to immobilize nanoparticles on a support to help particles stay ...

Green Synthesis and Characterisation of Magnetite Nanoparticles Using Factorial Design of Experiment

Olasupo Olayode Adesola*, Abdulkareem Ambali Saka, Kovo Abdulsalami Sani, Abubakre Oladiran Kamardeen

Magnetite nanoparticles have been produced by green synthesis method. Aqueous extract of Mangifera indica leaves was used as reducing agent for co-precipitation of magnetite from iron (II) and iron (III) salts 3 in 1:2 molar ratio. Optimisation of the process was carried out using 2 factorial design of experiments taking into consideration stir...

Optimization of the Green Synthesis of Tin Oxide Nanoparticles by Response Surface Methodology (RSM) using Box-Behnken Design.

Kareem Aduagba Ganiyu*, Abdulrahman Asipita Salawu, Abdulkareem Ambali Saka, Tijani Jimoh Oladejo

Tin oxide nanoparticles has been synthesized via green route using SnCl .2H O and Euphorbia trigona (African  2  2  cactus) plant extract as precursors. In this green route process parameters such as, solution pH, precursor concentration  and synthesis temperature were optimized to produce nanoparticles with smaller size. The degree of sensitivity ...
