Angle-independent solar radiation capture by 3D printed lattice structures for efficient photoelectrochemical water splitting

Abstract

Photoelectrochemical water splitting is one of the sustainable routes to renewable hydrogen production. One of the challenges to deploying photoelectrochemical (PEC) based electrolyzers is the difficulty in the effective capture...

Isotype heterojunction: tuning the heptazine/triazine phase of crystalline nitrogen-rich C3N5 towards multifunctional photocatalytic applications

“…The ameliorated current density is due to the well separation of electron–hole pairs in the CC3N5-500 sample. 68 The charge transfer ability was also confirmed through transient photocurrent responses (Fig. 6c).…”

Additive Manufacturing: A Paradigm Shift in Revolutionizing Catalysis with 3D Printed Photocatalysts and Electrocatalysts Toward Environmental Sustainability

“…attempted to create an angle‐independent solar radiation capturing device by DLP ( Figure B). [ 238 ] In recent years, a sudden surge has been experienced in the field of PEC semiconductors R&D. Yet, the same issue still emerged; inefficient solar capture due to the natural movement of sun's direction. Continuous tilting of the photoelectrode can serve as one solution, but the high energy consumption and mechanical design make them not viable for commercial application.…”

Modulation of charge-transfer behavior via adaptive interface treatment for efficient photoelectrochemical water splitting

“…Solar-driven photoelectrochemical (PEC) water splitting has been broadly regarded as a promising solution for sustainable and decarbonized technology in the quest of green and renewable energy. 1–7 Since TiO 2 photoanodes, researched by Fujishima and Honda, 8,9 were employed to perform water splitting to produce hydrogen, a majority of semiconductors, for example, TiO 2 , 10 α-Fe 2 O 3 , 11–14 Ta 3 N 5 , 15,16 and BiVO 4 , 17–22 have been regarded as ideal photoanodes for PEC water splitting in recent years. Among various candidates, BiVO 4 is the most promising candidate for PEC water oxidation because of a low bandgap (2.4 eV), low cost, and ideal band-edge positions.…”
