“…However, too much g-C 3 N 4 would block the incoming excitation light of TiO 2 , leading to less photogenerated electrons and holes, and turn into recombination centers of charge carriers instead, which would hinder electron transfer. 39–41 All of these conform to the PL result.…”

“…However, too much C 3 N 4 may reduce the availability of catalytic active sites, and become the center of recombination at which most photogenerated electrons and holes could recombine with each other and leave only a small part of charges participates in the photodegradation of tetracycline. 39,42–44…”

“…Figure 3 b shows the HRTEM image of 1-ATM. The marked crystal plane spacing of 0.351 nm is indexed to the anatase (101) crystal plane [ 21 , 37 ]. The lattice fringe of 0.228 nm can be ascribed to the crystal face of Ag (111) [ 38 , 39 ], indicating that Ag element exists as metallic Ag, which is consistent with the XRD results.…”

Ag/TiO2/muscovite (ATM) composites were prepared by the sol–gel method and the effects of Ag modification on the structure and photocatalytic performance were investigated. The photocatalysts were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer–Emmett–Teller surface area (BET), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectra (FTIR), photoluminescence spectra (PL) and ultraviolet–visible diffuse reflectance spectra (DRS). The photocatalytic activity of the obtained composites was evaluated by taking 100 mL (10 mg/L) of Rhodamine B (RhB) aqueous solution as the target pollutant. The muscovite (Mus) loading releases the agglomeration of TiO2 particles and the specific surface area increases from 17.6 m2/g (pure TiO2) to 39.5 m2/g (TiO2/Mus). The first-order reaction rate constant increases from 0.0009 min−1 (pure TiO2) to 0.0074 min−1 (150%TiO2/Mus). Ag element exists in elemental silver. The specific surface area of 1-ATM further increases to 66.5 m2/g. Ag modification promotes the separation of photogenerated electrons and holes and increases the visible light absorption. 1%Ag-TiO2/Mus (1-ATM) exhibits the highest photocatalytic activity. After 100 min, the rhodamine B (RhB) degradation degrees of PT, 150%TiO2/Mus and 1-ATM are 10.4%, 48.6% and 90.6%, respectively. The first-order reaction rate constant of 1-ATM reaches 0.0225 min−1, which is 25 times higher than that of pure TiO2.

“…[104] The non-TiO 2 -based photocatalysts are categorized as1) metal oxides such as ZnO and BiVO 4 ; [105] 2) metal sulfides, such as CdS (high occurrence), Cu 7 S 4 , ZnS, Bi 2 S 3 , PdS, [106] and NaBiS 2 ; [107] 3) bismuth metalates, such as Bi 2 WO 6 ; [108] 4) graphene-based photocatalysts, such as graphene-TiO 2 , under solar light irradiation; [109] and 5) carbon nitride photocatalysts, such as TiO 2 -based composites loaded with g-C 3 N 4 . [47] Hence, discovering new potent photocatalysts and lacking convincing technical applications have rendered TiO 2 irrelevant to research.…”

This study explores the decade‐long history of photocatalytic water treatment using a novel integration of the Delphi method and the preferred reporting items for systematic reviews and meta‐analyses approach, along with bibliometric analysis, to examine publication trends, author and country coauthorship networks, keyword co‐occurrence, citation analysis, and catalyst/contaminant evolution over time. The key findings include a steady increase in annual publications, a shift in dominant disciplines toward Environmental Sciences and Chemical Engineering, the role of specific authors in country productivity and citation rankings, and a growing need for international collaboration. TiO2‐ and TiO2‐based materials remain dominant, but a clear trend of abandonment in favor of novel materials is observed. Solar light is gaining importance for the photocatalytic elimination of aquatic pollutants, shifting simple organic compounds to priority substances. The evolution of this field is highlighted by tracing advancements in catalyst diversity and complexity, process optimization, and intensification. However, despite important milestone achievements, persistent knowledge gaps, discrepancies in comparability among studies, a lack of understanding of the fundamentals, and low funding incentives for transitioning to market hinder large‐scale applications. This study aims to provide a comprehensive guide for researchers by summarizing previous findings, unsuccessful approaches, and possibilities for improving photocatalytic applications.
