Its advantage is that it relies on mechanical energy and is independent of electricity and light source, unlike electrocatalysis or photocatalysis processes. In this research, 2H-MoS2/g-C3N4 heterojunction materials were successfully fabricated via the hydrothermal method and utilized as piezocatalyst in the treatment of Rhodamine B. This material exhibited a highly efficient piezo-catalyst effect, with the piezo-response amplitudes of 78.8 mV, almost doubled compared to 39.8 mV of 2H-MoS2. The degradation of Rhodamine B by ultrasonic irradiation could reach 75.4% only after 5 s and then 94.9% in 60 s without light assistance. This ultra-rapid degradation rate is attributed to the electron–hole pairs and transfer of the charge-carriers on the surface of 2H-MoS2 and g-C3N4 via S-scheme heterojunction model, which was confirmed by density functional theory study.

Our study takes a unique approach by focusing on immobilizing the white-rot fungus (WRF) Pleurotus sajor-caju onto a Luffa cylindrica plant support. This innovative method aims to facilitate the mycoremediation of agro-industrial pollutant pulp wash generated by the orange industry. The immobilization process significantly increased MnP enzymatic activity, reaching 23 IU.mL−1 and Lac activity at approximately 40.5 IU.mL−1. Qualitative SEM and FTIR analyses provided insights into the microorganism’s attachment mechanism to the support, suggesting that aggregation occurs due to an affinity to the lignocellulosic structure, enhancing the production of polysaccharides responsible for biocatalyst adherence and potential reusability. Furthermore, the production of an enzymatic extract rich in ligninolytic enzymes from P. sajor-caju showcased its ability to reduce the toxicity of pulp wash. An exploration into the toxicity of citrus effluent revealed the generation of embryos with severe deformities and the inhibition of Lactuca sativa germination, even at low concentrations. Notably, post-treatment with the enzymatic extract resulted in a remarkable 90% reduction in toxicity to the trophic level of Danio rerio and lettuce seeds. This research significantly contributes to understanding fungal immobilization strategies in environmental biotechnology, emphasizing the potential of agricultural residues as sustainable inducers for enzyme production and their pivotal role in mitigating the environmental impact of agro-industrial waste.","PeriodicalId":801,"journal":{"name":"Topics in Catalysis","volume":"40 1","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, steps towards waste water treatment must be taken. By using piezoelectric materials in the purifying process, a new area of waste water treatment known as piezo-photocatalysis has emerged. To improve the material’s water purification effectiveness, the piezoelectric action is paired with sun irradiation in this case. Up until this point, photocatalysis has served as a sophisticated method for purification. Thus, the piezoelectric materials became the center of attention in the quest for cutting-edge technologies for water purification. Piezoelectric materials have other potential applications outside of water treatment, including hydrogen production and carbon dioxide adsorption. The lead, barium, KNN, and bismuth perovskite compounds that have seen extensive usage in wastewater treatment are covered in this paper.

Various characterization methods were used to fully explore the crystalline character, morphological surface, chemical state and magnetic property of the prepared catalyst substances. In the presence of hydrogen peroxide (H2O2) as a green oxidant, the catalytic performance of RhB degradation using the proposed magnetic catalyst was explored. The experimental factors affected on the Fenton performance such as solution pH, catalyst concentration and H2O2 concentration were evaluated and optimized. Using the established protocol, 50 mg mL−1 of RhB can be completely at 15 min reaction time. Additionally, the used OFe-GO catalyst can be regenerated without losing the degradation performance for at least five cycles.
