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 energyrelated 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.

Methods: 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.
