Influence of Morphology Change on Photoelectrochemical Activity of Cerium Oxide Nanostructures

Abstract

Aims: Photocatalysis has become a crucial area in the field of energy generation Background: The conversion of solar energy into chemical or thermal energy for various energy related applications has taken precedence over many traditional research areas. Objective: The urgency to become independent of non-renewable energy resources is paramount due to issues of global warming. Objective: The urgency to become independent of non-renewable energy resources is paramount due to issues of global warming. Method: To that end, researchers are exploring various material systems, geometries and material combinations to obtain ideal photocatalysts for efficient solar conversion. Here, the nanostructures were fabricated via electrodeposition. Results and Discussion: The morphology was controlled by varying the concentration of chemical additive, namely dimethyl sulfoxide, during the deposition process. The morphology controlled cerium oxide nanostructures were thoroughly characterized and tested for their photoelectrochemical performances. Conclusion: Our present investigation contributes to this area of research by studying the influence of morphology on the photoelectrochemical activity of cerium oxide nanostructures.
