Nanosized CeO2-CuO (CeCu, 2:1) and CeO2-CoO (CeCo, 2:1) were synthesized by co-precipitation from nitrate precursors using 25% ammonia solution (NH4OH) as the precipitating agent. The catalysts were calcined in air at 800°C for 4h to evaluate the thermal stability. Powder x-ray diffraction (XRD) and Dynamic Light Scattering (DLS) techniques were used for catalyst characterization. A Thermo Gravimetric/Differential Thermal Analyzer (TG/DTA) was used to determine the catalytic efficiency and soot oxidation activity. Ce-composite nanoparticles heightens the redox properties of the catalyst relative to undoped ceria. The Ce-composite samples exhibited excellent soot catalytic combustion performance by decreasing activation energy of soot oxidation.

Efficient energy generation and utilization of both energy resources and energy by the end user will play a significant role in the socio-economic development and generation of wealth in Zimbabwe. One of the most promising renewable energy source in the country is Solar Energy. In recent years, solar energy has received much attention as an easily utilizable energy source of electricity. If proper systems and technology are used, solar energy can provide an environmental friendly option and national energy security for a long-term sustainability of the Zimbabwean economy. This paper describes the potential of Advanced Solar Energy Generation by integrating Nano Carbon Electrical Energy Storage System to improve the energy sector in Zimbabwean perspective.
