The escalating demands for energy sources and cumulative global environmental apprehensions have synergistically contributed to advancements in solar-driven technologies to utilize renewable energy resources. Photocatalytic water splitting, which is considered the most promising and sustainable process to harness solar energy for H 2 and O 2 evolution, is of particular interest. The photocatalytic performance of Ag 3 PO 4 is attributed to its visible-light active 2.43 eV band gap energy, tunable facet crystal structure, and high thermal stability. The suitable valence band (+ 2.85 V) potential of Ag 3 PO 4 is suggestive of its extraordinary oxidation capability. Herein, recent advances in preparation, characterization, and photocatalytic activity of silver orthophosphate (Ag 3 PO 4 ) based photocatalytic materials for water splitting are reviewed. The well-suited synthesis methods and rational engineering aspects for eliminating the significant limitations of self-photocorrosion and minimum absorption in the solar spectrum are highlighted. The achievement of Ag 3 PO 4 -based photocatalytic materials in water splitting is elaborately discussed, with the main focus on heterostructure formation, facet morphology, and plasmonic phenomena. Besides, some vital accomplishments in bandgap modulation and attaining the required surface energy to achieve an attractive yield of H 2 and O 2 in the region of visiblelight are also presented. Finally, a conclusive summary outlines this all-inclusive review with appropriate recommendations for photocatalytic water splitting to meeting a green approach shortly. We expect this comprehensive study could provide a guideline to tailor more efficient Ag 3 PO 4 -based photocatalytic materials with broad research prospects toward water splitting and other sustainable applications.

Among the technologies proposed for wastewater treatment, the Advanced Oxidation Processes are viable and technological strategies for dyes degradation. Different photocatalytic systems classified in metal oxides alone or combined through hybrid composites or immobilized onto supports have been designed in various nanostructured shapes for their application in the photodegradation of polluting dyes. This review aims to describe the dyes as an environmental threat, photocatalysis as an effective process to remove dyes from water and provide an overview of the recent studies using photocatalytic systems grouped according to their development. Furthermore, this review describes the main parameters of a photocatalytic system with an important role in dye photodegradation. Finally, we discuss the limitations of photocatalysis for real industrial applications and the challenges for this environmental nanotechnology.

“…In recent years, silver-based photocatalysts have attracted widespread attention. Among them, Ag 3 PO 4 has been extensively studied due to its narrow band gap (about 2.40 eV) and excellent photocatalytic activity under visible light [15][16][17]. However, the speedy recombination of photoexcited electron-hole pairs and poor light stability severely weakens its photocatalytic performance [18][19][20][21][22].…”

In this study, the Ag3PO4/SnO2 heterojunction on carbon cloth (Ag3PO4/SnO2/CC) was successfully fabricated via a facile two-step process. The results showed that the Ag3PO4/SnO2/CC heterojunction exhibited a remarkable photocatalytic performance for the degradation of Rhodamine B (RhB) and methylene blue (MB), under visible light irradiation. The calculated k values for the degradation of RhB and MB over Ag3PO4/SnO2/CC are 0.04716 min−1 and 0.04916 min−1, which are higher than those calculated for the reactions over Ag3PO4/SnO2, Ag3PO4/CC and SnO2/CC, respectively. The enhanced photocatalytic activity could mainly be attributed to the improved separation efficiency of photogenerated electron-hole pairs, after the formation of the Ag3PO4/SnO2/CC heterojunction. Moreover, carbon cloth with a large specific surface area and excellent conductivity was used as the substrate, which helped to increase the contact area of dye solution with photocatalysts and the rapid transfer of photogenerated electrons. Notably, when compared with the powder catalyst, the catalysts supported on carbon cloth are easier to quickly recycle from the pollutant solution, thereby reducing the probability of recontamination.
