Herein, a perovskite oxide material, strontium titanate (SrTiO3, STO), is synthesized via a sol–gel method and employed for the first time as an efficient advanced electrocatalyst for the degradation of organic pollutants. The STO electrode annealed at 900 °C demonstrates superior degradation efficiency, achieving 86.3% removal of 60 mg L−1 chlortetracycline. This outstanding activity stems from the optimized crystal structure and enhanced surface redox properties of STO, which significantly boost OH radical generation. Compared to recent electrocatalysts, STO achieves competitive degradation efficiency and lower energy consumption under mild conditions, highlighting a notable performance breakthrough. Mechanistic insights, obtained through liquid chromatography–mass spectrometry and radical scavenging experiments, reveal that hydroxyl radicals (·OH) play a dominant role in the degradation process. Moreover, STO demonstrates exceptional long-term stability and broad applicability in degrading various antibiotics, underscoring its versatility and potential for treating complex organic wastewater. This work establishes STO as a cost-effective and scalable electrocatalyst with high stability and energy efficiency, addressing key challenges in electrocatalytic degradation and advancing the use of perovskite materials in environmental remediation.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 7","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144598727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These problems have been addressed by triboelectric nanogenerators that convert droplets, waves, and flows of mechanical power into electricity. This paper aims to review the antecedents of solid–liquid triboelectric nanogenerators (SL-TENG) while focusing on lightweight, cost efficiency, and sustainability. SL-TENGs are appropriate for industrial, environmental, and marine environments because of their capacity to convert liquid flow into electrical power. However, they have drawbacks, including material degradation, biofouling, corrosion, and ecological effects that constrain their performance and durability. It has been suggested that advanced materials and coatings, such as superhydrophobic surfaces, self-healing layers, and composites, be featured to overcome these challenges. Processes such as solgel deposition, plasma-enhanced techniques, and spray coatings boost their sturdiness and functionality. The paper focuses on performance reviews involving triboelectric output, corrosion, mechanical stability, and the ability to demonstrate how new designs and coatings have determined SL-TENG efficiency. Therefore, this review will be a clear roadmap to realize efficient and durable SL-TENG technologies for future energy harvesting systems.","PeriodicalId":54339,"journal":{"name":"ChemNanoMat","volume":"11 8","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first synthesis, a molar ratio of 1:26 (Co2:2-methylimidazole) results in particles with an average diameter of 230 nm and a surface area of 1374 m2 g−1. The first recycling step produces ZIF-67 particles that doubl in diameter and surface area, reaching 520 nm and 1690 m2 g−1, respectively. In the second recycling step, the particles further increase to 1040 nm in diameter and 1806 m2 g−1 in surface area. This increase in diameter is attributed to changes in the metal-to-ligand ratio, which affects the nucleation and growth rates. Increased surface area is linked to a reduction in the average micropore diameter, which decreases from 1.42 nm (first synthesis) to 1.37 nm (second recycling step).
