Palladium nanoparticles are of great importance as catalytic materials, as well as for a number of other applications such as hydrogen storage, surface enhanced Raman scattering, sensors, study of size-dependent properties, and fabrication of high-order structures. High-yield synthesis of Palladium Nanocubes were synthesized by a single step addition of CTAC and AA as the surfactant and reducing agent respectively using seeded growth approach. Unlike existing methods which consist of multiple experimental procedures and conditions, in this report, we introduce the use of single step chemical reduction and condition-free method. Reducing experimental complexity and thus, improving reproducibility. Reproducibility is an essential principle of the scientific process where any idea that a discovery is valid only if any scientist in any lab can conduct the same experiment under the same conditions and obtain the same results in order to build upon it. As such, in this project, we aim to simplify experimental procedures and conditions to optimise the chances of reproduction. The results were examined under Scanning Electron Microscopy and Ultraviolent Spectrometry. In addition, other Pd nanoparticles morphologies were also investigated using single step and condition-free methods.
