Transitioning to lower carbon energy and environment sustainability requires a reduction in greenhouse gases such as dioxide (CO2) methane (CH4) that contribute global warming. One of the most actively studied rare earth metal catalysts is cerium oxide (CeO2) which produces remarkable improvements dry reforming methane. This paper reviews management CO2 emissions recent advent trends bimetallic...
The influence of a cerium additive on the kinetics of oxidation and size distribution of ultrafine diesel particles was studied using a high-temperature oxidation-tandem differential mobility analysis method over the temperature range 300–700 ◦C. The addition of cerium to the diesel fuel was observed to cause significant changes in numberweighted size distributions, light-off temperature, and k...
Traditional nanostructured design of cerium oxide catalysts typically focuses on their shape, size, and elemental composition. We report a different approach to enhance the catalytic activity of cerium oxide nanostructures through engineering high density of oxygen vacancy defects in these catalysts without dopants. The defect engineering was accomplished by a low pressure thermal activation pr...
