To design the shape of nanocrystals in one of the most important issues in nanoscience, chemistry, and physics
owing to the close correlations between the surface morphology and the surface energy and chemical reactivity.
Preferential adoption of-of organic and inorganic additives on certain crystallographic surfaces offer a good opportunity
to tune and control the surface activities of nanomaterials. The ability to understand, predict and control of exposed
surfaces is of critical importance to elucidate and explore shape-dependent chemical and physical properties. Cuprous
oxide Cu2O is a p-type semiconductor, which can be operated at relatively low temperatures. It posses high stability and
good electrocatalytic characteristics. The conductivity of Cu2O is mainly determined by the hole carrier density of the
inter-granular contact region. Moreover, materials based on copper are the most evolving group due to their redox pair
Cu2+/Cu3+. Presented work aims to investigate the influence of the copper oxide nanostructures with well-defined faces
towards their electrochemical sensing activity. Different morphologies of Cu2O nanocrystals were synthesized by a typical
wet-chemical technique in the presence of various capping/reducing agents. The morphology of obtained materials
was analyzed by SEM observation. The XRD, FTIR and Raman spectroscopy measurements were carried out for phase
analysis. The surface properties were determined by DLS and zeta potential measurements. Electrochemical behavior
towards glucose, hydrogen peroxide, and hydrazine detection was investigated by cyclic voltammetry.
