Control over the topography of semiconducting materials can lead to enhanced performances in photoelectrochemical related applications. One means of implementing this is through direct patterning of metal-based substrates, though this is inadequately developed. Conventional techniques for patterned fabrication commonly involve technologically demanding and tedious processes. 3D printing, a form of additive fabrication, enables creation of a 3D object by deposition of successive layers of material via computer control. In this work, the feasibility of fabricating metal-based 3D printed photoelectrodes is explored. Electrodes comprised of conical arrays are fabricated and the performance for photoelectrochemical water splitting is further enhanced by the direct growth of TiO2 nanotubes on this platform. 3D metal printing provides a flexible and versatile approach for the design and fabrication of novel electrode structures. Advanced 3D-printed conical arrays of Ti-substrates are acting as substrates to form TiO2-based photoanodes with enhanced photoelectrochemical water splitting performance. Tunable sizes and densities of conical arrays are achievable from 3D printing technology. These 3D printed metal-based structures in addition to ease of functional modifications open a new way in fabricating novel electrode materials for photoelectrochemical related applications.
