2D Methyl Germanane Enhanced 3D Printed Photoelectrodes

Abstract 3D printing is a cutting‐edge technology, that allows the printing of 3D objects according to the design provided. Nanocarbon electrodes that can be fabricated using 3D printing technology, suffer from a lack of required properties. For enhancing the photoelectrochemical properties of 3D printed electrodes, functionalized germanenes, belonging to the family of 2D materials are used here. Functionalized germananes are becoming popular for application in photoelectrochemical processes, due to their photoactivity in the visible spectral region and their tunable optoelectronic properties, thanks to covalent functionalization. It is shown that 2D methyl germanane has great potential for photoelectrocatalytic enhancement of 3D printed structures, and this potential goes beyond the demonstrated application of water splitting.
