“…According to the ISI-XPS testing results, compared with the dark environment, the binding energy of both P 2p and O 1s exhibits a positive shift after the light irradiation, which proves that Ag 3 PO 4 loses the electrons. However, I 3d has a significant negative shift, indicating AgI captures the electrons during the photocatalysis . Hence, the S-scheme heterojunction formed at the interface of the composite sample could transfer electrons from Ag 3 PO 4 to AgI until the Fermi level is consistent (Figure S7d).…”

At the moment, the VB position of AgI (3.55 eV) is far more positive than that of H 2 O/ • OH (2.72 eV), so the • OH generated from the h + can play a role in the photocatalytic reaction process.…”

A silver phosphate (Ag 3 PO 4 )/silver (Ag)/silver halide (AgX, X = Cl, Br, or I) ternary composite photocatalysts were prepared by loading Ag nanoparticles on Ag 3 PO 4 tetrapods followed with in situ halogenation. The interface charge transfer behavior in the Ag 3 PO 4 /Ag/AgX nanocomposite was studied, and the photocatalytic performance was also evaluated. The results show that the Ag 3 PO 4 /Ag/AgI photocatalyst exhibits higher photocatalytic activity than the other two photocatalysts due to the more matched band structure between AgI and Ag 3 PO 4 . An internal electric field (IEF) from Ag 3 PO 4 to AgI is formed at the heterogeneous interface, so the photogenerated electrons at the conduction band of AgI can rapidly transfer to the valence band of Ag 3 PO 4 and recombine with photogenerated holes, which is consistent with the S-scheme charge transfer mechanism. Meanwhile, the photogenerated electrons left at the conduction band of Ag 3 PO 4 can transfer to Ag nanoparticles due to the Schottky junction and react with oxygen to produce • O 2 − , which is proved to be the main active species in the photocatalytic procedure. This tandem junction modulated between the S-scheme heterojunction and Schottky junction promotes the efficient separation of photogenerated carriers, thus significantly increasing the average PL lifetime of electrons by 2.95 times. Therefore, the Ag 3 PO 4 /Ag/AgI photocatalyst exhibits excellent photocatalytic activity for the degradation of methylene blue and norfloxacin. The seven consecutive cyclic tests prove the good stability of the photocatalyst, thus showing the application potential in the field of sewage treatment.

Semiconductor‐based materials utilized in photocatalysts and electrocatalysts present a sophisticated solution for efficient solar energy utilization and bias control, a field extensively explored for its potential in sustainable energy and environmental management. Recently, 3D printing has emerged as a transformative technology, offering rapid, cost‐efficient, and highly customizable approaches to designing photocatalysts and electrocatalysts with precise structural control and tailored substrates. The adaptability and precision of printing facilitate seamless integration, loading, and blending of diverse photo(electro)catalytic materials during the printing process, significantly reducing material loss compared to traditional methods. Despite the evident advantages of 3D printing, a comprehensive compendium delineating its application in the realm of photocatalysis and electrocatalysis is conspicuously absent. This paper initiates by delving into the fundamental principles and mechanisms underpinning photocatalysts electrocatalysts and 3D printing. Subsequently, an exhaustive overview of the latest 3D printing techniques, underscoring their pivotal role in shaping the landscape of photocatalysts and electrocatalysts for energy and environmental applications. Furthermore, the paper examines various methodologies for seamlessly incorporating catalysts into 3D printed substrates, elucidating the consequential effects of catalyst deposition on catalytic properties. Finally, the paper thoroughly discusses the challenges that necessitate focused attention and resolution for future advancements in this domain.
