3D-printed Cu₂O photoelectrodes for photoelectrochemical water splitting

Abstract

Cu2O 3D photoelectrode for PEC water splitting are realized by a sequential process including extrusion-based 3D printing and electrodeposition.

Development and Optimization of Medical-Grade Multi-Functional Polyamide 12-Cuprous Oxide Nanocomposites with Superior Mechanical and Antibacterial Properties for Cost-Effective 3D Printing

“…To overcome these issues and improve the performance of the parts produced by the FFF technology, composite materials are developed using well-established polymers in engineering applications (usually called engineering-grade polymers) as the matrix. Such composites are fabricated using fillers in micro/nano or fiber form to achieve improved mechanical [ 12 , 35 , 36 ], thermal [ 37 , 38 , 39 ], or electrical performance [ 11 , 40 , 41 ], compared to the matrix alone. Many additives hinder the flow of the material, so several studies on the flowability of composites exist in this field [ 12 , 42 ].…”

“…Copper (I) oxide (cuprous oxide), is met with the chemical formula of Cu 2 O. It is an inorganic compound with a cubic crystal structure [ 56 ] and is utilized in a wide range of applications, such as semiconductors [ 41 , 57 ], medical applications [ 58 , 59 , 60 ], and others. Copper (I) oxide’s antibacterial performance has been studied and it is well documented in the literature [ 61 , 62 ].…”

Improved Interfacial Charge Transfer on Noble Metal‐Free Biomimetic CdS‐Based Tertiary Heterostructure @ 2D MoS2‐CdS‐Cu2O with Enhanced Photocatalytic Water Splitting

“…[ 17 ] On the other hand, Cu 2 O with a bandgap of 2.2 eV can act as p‐type semiconductors based on the synthesis condition [ 18 ] and hence more attention has been given in recent times as a potential photocatalyst. [ 19,20 ] Moreover, surface morphology and the anisotropic effect of Cu 2 O [ 21 ] influence the photocatalytic hydrogen production efficiency to much extent which clearly underlined the importance of shape and structure of photocatalyst. [ 22,23 ] However, CdS and Cu 2 O suffer from catalyst deactivation due to photocorrosion in an aqueous medium [ 24 ] and fast electron and hole recombination rate resulting in low photocatalytic activity.…”

Trilateral Multi-Functional Polyamide 12 Nanocomposites with Binary Inclusions for Medical Grade Material Extrusion 3D Printing: The Effect of Titanium Nitride in Mechanical Reinforcement and Copper/Cuprous Oxide as Antibacterial Agents

“…It has been processed and investigated in AM as well [ 60 , 61 , 63 , 64 , 65 , 66 ], with several works exploiting its antibacterial performance in AM [ 34 , 65 ]. Cuprous oxide has been employed in semiconductors [ 67 , 68 ], among other applications; still, it is mainly used and investigated for its antibacterial properties [ 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 ]. Its antibacterial properties have also been exploited in vat photopolymerization [ 32 , 34 ] and MEX 3DP for polylactic acid (PLA) [ 35 ] and PA12 polymers [ 8 ], achieving sufficient antibacterial performance in the nanocomposites developed in these studies.…”
