Special Issue Information

Dear Colleagues,

This Special Issue, entitled “Chemical Research on Photosensitive Materials, 2nd Edition”, aims to discuss the design, synthesis, characterization, and application of photosensitive materials. Photosensitive materials include photochromic materials, photoluminescence materials, photothermal materials, photovoltaic materials, and photocatalysts; most of them have exhibited important applications in detection/indication, energy conversion, environmental protection, and phototherapy. Photosensitive materials may be composed of small molecular compounds, polymers, inorganic materials, or organic–inorganic hybrids. The key focus of this Special Issue is on the relationships among the structure, properties, and applications of photosensitive materials, especially novel designs of structures that lead to advanced properties and extended applications.

Abstract
Bismuth oxychloride (BiOCl)– copper oxide (CuO) heterostructures were synthesized via a solvothermal route and assessed as visible-light-driven photocatalysts for methyl orange (MO) degradation. Different CuO loadings deposited on BiOCl microspheres were investigated to identify the optimal composition. Structural and physicochemical characterization revealed that [...] Read more.
Bismuth oxychloride (BiOCl)– copper oxide (CuO) heterostructures were synthesized via a solvothermal route and assessed as visible-light-driven photocatalysts for methyl orange (MO) degradation. Different CuO loadings deposited on BiOCl microspheres were investigated to identify the optimal composition. Structural and physicochemical characterization revealed that low CuO content (0.6 wt. %) promoted uniform dispersion and enhanced surface area, whereas higher loadings led to nonuniform coverage and reduced photocatalytic efficiency. Operating conditions were optimized using response surface methodology based on a central composite design, considering catalyst dosage (0.1–0.8 g L−1) and pH (4–9). The highest degradation efficiency (~50% after 60 min irradiation) was achieved at pH = 4 and a catalyst dosage of 0.8 g L−1 using the BiOCl surface modified with 0.6% CuO. Kinetic analysis followed a pseudo-first-order model. Mass spectrometry identified transient intermediates associated with demethylation and desulfonation pathways, while radical scavenger experiments confirmed hydroxyl radicals (OH) as the dominant oxidizing species, with a secondary contribution from superoxide radicals (O2). These results highlight the critical role of CuO dispersion and interfacial quality in enhancing charge separation and photocatalytic performance, providing practical guidelines for the rational design of BiOX-CuO heterostructures for water remediation applications.

Metal–organic frameworks (MOFs) possess ordered pore structure, high surface area, tunable composition and tailorable functionality, and thus present promising prospect in many applications. Among them, titanium-based MOFs (Ti-MOFs) composed of organic ligands and titanium–oxygen clusters exhibit great potential in photocatalysis, owing to their diverse topological configurations, outstanding photocatalytic activity, low toxicity, and easy production. The latest developments in Ti-MOFs, including the synthetic strategies, structural features, methods for enhancing catalytic performance, and typical applications, were reviewed in this paper. The application in CO2 reduction, hydrogen evolution, organic pollutant removal, and photocatalytic sensing were emphasized. Moreover, we present a distinctive perspective on the relationship between the structure and their applications of Ti-MOFs, and provide new information in the design and construction of advanced Ti-MOFs for high-efficiency photocatalytic conversion.

Bismuth-based oxyfluorides (BiOxF3−2x) have recently emerged as promising photocatalysts due to their unique electronic structures and tunable physicochemical properties. This review provides a comprehensive overview of these materials, focusing on their crystal structures, band gap characteristics, and photocatalytic performance. Particular attention is given to BiOF, Bi7O5F11, and β-BiOxF3−2x, highlighting the influence of fluorine’s high electronegativity and internal electric fields on charge separation and light absorption. The potential of Aurivillius-type oxyfluorides is also discussed. Structural modifications, such as the introduction of oxygen vacancies, morphology control, and metal/non-metal doping, are examined for their effects on photocatalytic efficiency. Furthermore, various synthesis techniques and heterojunction engineering strategies involving semiconductors, carbon-based materials, and metal nanoparticles are explored to improve light harvesting and reduce charge recombination. Applications in pollutant degradation and CO2 photoconversion are reviewed, demonstrating the versatility of these materials. Despite their promise, the challenges associated with phase identification and composition control are also emphasized, underlining the need for rigorous structural characterization. Future directions for optimizing the photocatalytic activity of bismuth-based oxyfluorides are outlined, focusing on strategies to enhance their performance. Full article
