One of the most challenging problems for people around the world is the lack of clean water. In the past few decades, the massive discharge of emerging organic pollutants (EOPs) into natural water bodies has exacerbated this crisis. Considerable research efforts have been devoted to removing these EOPs due to their biotoxicity at low concentrations. Heterogeneous photocatalysis via coupling clay minerals with nanostructured semiconductors has proven to be an economical, efficient, and environmentally friendly technology for the elimination of EOPs in drinking water and watershed water. Natural zeolite minerals (especially clinoptilolites) are regarded as appropriate supports for semiconductor-based photocatalysts due to their characteristics of having a low cost, environmental friendliness, easy availability, co-catalysis, etc. This review summarizes the latest research on clinoptilolites used as supports to prepare binary and ternary metal oxide or sulfide semiconductor-based hybrid photocatalysts. Various preparation methods of the composite photocatalysts and their degradation efficiencies for the target contaminants are introduced. It is found that the good catalytic activity of the composite photocatalyst could be attributed to the synergistic effect of combining the clinoptilolite adsorbent with the semiconductor catalyst in the heterogeneous system, which could endow the composites with an excellent adsorption capacity and produce more e−/h+ pairs under suitable light irradiation. Finally, we highlight the serious threat of EOPs to the ecological environment and propose the current challenges and limitations, before putting the zeolite mineral composite photocatalysts into practice. The present work would provide a theoretical basis and scientific support for the application of zeolite-based photocatalysts for degrading EOPs.

“…Metal oxides, metal ferrites, and metal sulfides are examples of semiconductors, which have particular band gap energies. Semiconductor nanomaterials have been widely used because of their ability to harness light energy and produce charged carriers [26,[28][29][30]. The typical mechanism involving semiconductors is depicted in Figure 2.…”

“…In this review, we focus solely on photochemical processes, particularly highlighting the use of photosensitizing catalysts in the degradation of pesticides. Mechanistic and reaction pathways have been adequately discussed in previous literature [22][23][24][25][26] and are not the main focus of this review; however, we provide a brief introduction with references to mechanistic considerations before reviewing and discussing multiple pivotal works that report several important photochemical approaches. Finally, we will analyze the literature regarding the application of tetrapyrrolic macrocycle photosensitizers on the photodegradation of pesticides.…”

Exposure to pesticides is inevitable in modern times, and their environmental presence is strongly associated to the development of various malignancies. This challenge has prompted an increased interest in finding more sustainable ways of degrading pesticides. Advanced oxidation processes in particular appear as highly advantageous, due to their ability of selectively removing chemical entities form wastewaters. This review provides a concise introduction to the mechanisms of photochemical advanced oxidation processes with an objective perspective, followed by a succinct literature review on the photodegradation of pesticides utilizing metal oxide-based semiconductors as photosensitizing catalysts. The selection of reports discussed here is based on relevance and impact, which are recognized globally, ensuring rigorous scrutiny. Finally, this literature review explores the use of tetrapyrrolic macrocyclic photosensitizers in pesticide photodegradation, analyzing their benefits and limitations and providing insights into future directions.

Photocatalysis represents a solar‐to‐chemical energy transformation process including three processes, light absorption, charge separation/transfer, and surface reactions. Owing to the merits of single‐atom catalysts (SACs) toward maximal atom utilization, unsaturated coordination structure, and tunable electronic configuration, single‐atom photocatalysts (SAPs) exhibit extraordinary photocatalytic performance toward a series of sustainable reactions. Accompanied by the complexity of photocatalytic processes and the realistic demand for tandem reactions as well as the promotion of intricate reactions with multiple reaction routes and intermediates, significant efforts are desired to gain in‐depth insights into the design and fabrication of synergistic photocatalysts. In this review, the first part discusses the design principles from traditional semiconductor‐based photocatalysts to SAPs. Moreover, six basic models of synergistic photocatalysts including remote dual atoms, bridged dual atoms, adjacent dual atoms, single atoms + clusters/nanoparticles (NPs), single atoms + defects, NPs + NPs, are highlighted and distinguished by their structure features. Second, specific examples of SAPs and synergistic photocatalysts are appreciated under the category of CO2 reduction reaction (CO2RR), hydrogen evolution reaction (HER), nitrogen reduction reaction (NRR), and pollutants degradation. Finally, this review will conclude by discussing the challenges and future perspectives of SAPs and synergistic photocatalysts for sustainable applications.
