Acoustic cavitation exploits high-frequency ultrasonic waves to generate transient and stable bubbles, leading to localized high temperatures, pressures, and reactive species formation. Hydrodynamic cavitation, achieved through fluidic devices, such as Venturi tubes and vortex diodes, generates cavities under controlled low-pressure zones, providing scalable solutions for large-scale operations. This study critically examines the industrial viability of cavitation technologies, emphasizing their unique ability to combine mechanical, thermal, and chemical energy release. A detailed comparative analysis reveals the limitations of acoustic cavitation, including energy attenuation and equipment wear, against the superior scalability of hydrodynamic systems. Key challenges, such as enhancing hydroxyl radical yield, reducing operational costs, and improving system robustness, are explored alongside potential synergies with complementary technologies, like advanced oxidation processes and photocatalysis. Emerging industrial implementations, including biogas enhancement and chemical processing, underscore the evolving landscape of cavitation-based innovations.

Furthermore, due to their extensive usage, per- and polyfluoroalkyl substances (PFAS) and endocrine-disrupting chemicals (EDCs) have emerged as significant global concerns due to their pervasive presence and substantial accumulation in aquatic ecosystems. Research to date has primarily focused on these contaminants in isolation, leaving the interactions and cumulative effects among MPs, PFAS, and EDCs (trifecta) relatively unexamined. We elucidate the probable interaction mechanisms among these three categories of contaminants and to analyze their combined toxicity, as well as the existing regulatory frameworks and policies applicable to them. Our findings indicate that the sorption of EDCs and PFAS onto MPs is predominantly governed by hydrophobic and electrostatic forces and is sensitive to various environmental parameters, including pH, salinity, temperature, and dissolved organic matter. The interactions among these contaminants are intricate, encompassing mechanisms such as cation-π bonding and biofilm formation, all of which influence the dynamics of sorption. The synergistic effects of MPs in conjunction with co-contaminants, such as PFAS and EDCs, exacerbate toxicity, promote bioaccumulation, and elevate health risks for both aquatic organisms and mammals, typically contingent upon factors such as exposure duration, dosage, and environmental conditions. In conclusion, we underscore that while significant advancements have been achieved, considerable efforts are still required to address regulatory deficiencies and to advance legislation aimed at mitigating the impact of persistent pollutants.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101126"},"PeriodicalIF":8.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143799288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional strategies to enhance charge separation include solid–solid junctions, facet engineering, and cocatalyst addition. This review explores an alternative approach using ferroelectric materials to improve photoelectrochemical (PEC) water splitting efficiency. Ferroelectric materials exhibit spontaneous electric polarization, generating internal electric fields that modulate band bending at the solid–liquid interface. This intrinsic property enhances charge carrier separation and directs photogenerated electrons and holes toward specific redox sites or cocatalysts. We highlight key studies demonstrating the effectiveness of ferroelectric materials in PEC applications. Electric polarization of BiFeO<sub>3</sub> thin films resulted in controlled enhancement of water oxidation by directly influencing band bending and charge transfer processes. Similarly, BaTiO<sub>3</sub>–TiO<sub>2</sub> core–shell structures with Ni(OH)₂ cocatalysts exhibited improved PEC activity through polarization-mediated charge separation. BaTiO<sub>3</sub> particles also demonstrated enhanced PEC water oxidation and hydrogen evolution in both film and suspension systems due to ferroelectric effects. These findings underscore the potential of ferroelectric materials to optimize charge carrier dynamics in photocatalytic processes for better solar energy conversion.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101123"},"PeriodicalIF":8.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of ultrasound in electrochemical processes such as water electrolysis can lead to an energy efficiency enhancement in the range of 2–25% in low-temperature water electrolysers (LT-WE).

The main objectives of this review are to highlight recent advancements in using power ultrasound in water electrolysis and shed some light on possible commercial development by addressing the fundamental obstacles that lie in this technology.

However, even with the observed higher efficiencies from the <em>sonoelectrolysers</em> for hydrogen production in R&D labs, this technology still faces challenges for further development due to the efficiency in competing with commercial LT-WEs, which are already in the range of 60–70%.
