Carbon dioxide is one of the gases that have amplified the greenhouse effect that, in turn, results in a warmer atmosphere. Many innovative designs and technologies have been established to slow down the climate change that is known to result from an amplified greenhouse effect. Among these technologies include Chemical Looping Combustion and the NanoCO 2 .
Chemical looping combustion
The CLC is a dual step combustion technology for heat and power generation with the inherent carbon dioxide capture with the utilization of either solid, liquid, or gaseous fuels. This technology offers a better alternative to produce energy while eliminating the emission of CO2. The system comprises of two reactors where natural gas or coal is burned together with the metal oxide that are converted to their respective meals. The second reactor is used for conversion of the metal into its original metal oxide form. CLC splits combustion gases into nitrogen that is first collected during the combustion. The steam condenses to produce water while the gas by-product is pure carbon dioxide ( Kronberger, Lyngfelt, Löffler, & Hofbauer, 2005) .

NanoCO 2
The nanometals can be used to efficiently separate the carbon dioxide from nitrogen and other materials emitted into the atmosphere. This would permit the separation of CO2 and hence preventing the release into the atmosphere. The metal-organic framework has a remarkable selectivity to isolate CO 2 from nitrogen. Amines are attached to these nanoparticles to quicken the process of carbon dioxide capture. A hybrid class of hybrid substances are preferred for this separation process due to their ability to improve the efficiency of carbon dioxide capture. Compared to other methods used to separate carbon dioxide, the use of nanomaterials is relatively less expensive, and it is less energy intensive ( Valverde, Perejón, & Perez-Maqueda, 2012) .
