This has prompted extensive research efforts focused on the fabrication structure and enhancement of the electronic characteristics, structure modification, and applications of these one-dimensional substrates as TNT-based electrocatalysts. This review comprehensively addresses all these topics, which were not previously covered. It begins with the preparation techniques, modification strategies of TNTs, and the formation of TNT factors, elaborating on each in depth. The review also discusses the chemical and physical properties of TNTs, the fundamental principles of the electrocatalytic process using TNTs, and their application in water electrolysis and CO₂ reduction. The main electrocatalytic potential of TNTs, including hydrogen and oxygen gas generation, is discussed extensively, considering the reported experiments conducted in the last decade. For example, 1D TNTs supported PtOx nanoclusters were studied as a more effective electrocatalyst for the hydrogen evolution reaction, achieving an overpotential of -30 mV to produce -10 mA cm⁻². Thus, the PtOx/TNTs electrocatalyst was superior to that of PtOx loaded on TiO₂ nanoparticles and the benchmark electrode (Pt/C). This outstanding activity can be attributed to the strong interaction between the TNTs and the Pt nanoclusters. This review aims to enhance understanding of TNT-based nanostructured materials and their potential applications as effective substrates in electrocatalytic processes. The challenges of using conductive or semiconductor support for loading the co-catalyst in the future include the need for it to be low-cost, robust, scalable, and sustainable; however, titanium oxide nanotubes (TNTs) can address all of these challenges and pave the way for long-term sustainable energy applications.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"31 7","pages":"6601 - 6633"},"PeriodicalIF":2.6,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, one-dimensional models are commonly employed to quickly investigate the thermo-hydraulic behavior of fuel cells under various start-up strategies, while three-dimensional models offer more intuitive insights into internal mass transport and phase change phenomena. However, the influence of key material properties on cold start performance remains insufficiently explored and warrants further investigation. Accordingly, this study develops a one-dimensional multiphase model to investigate how key material parameters affect fuel cell cold start performance. Results show that optimizing parameters such as the thickness and contact angle of the catalyst layer, gas diffusion layer thickness, and membrane thickness can significantly reduce ice formation and improve cold start success. Specifically, thicker gas diffusion layers enhance moisture management, while an 8-μm catalyst layer balances ice accommodation and voltage output. Higher contact angles lower freezing points, and increased membrane thickness delays freezing and boosts internal heat. These optimizations notably improve cold start performance at − 10 °C and − 15 °C.</p></div>","PeriodicalId":599,"journal":{"name":"Ionics","volume":"31 7","pages":"7105 - 7123"},"PeriodicalIF":2.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This investigation primarily centres on the hydrothermal synthesis of ZnO/Ti₃C₂T_x composites, poised for application in the photocatalytic breakdown of dyes. The FESEM analysis reveals the transformation of particulate ZnO to fleet-like decoration assisted by the MXene flakes and however some of the ZnO particles got embedded onto the surface and growing in the interlayers.

Remarkably, the composite demonstrated exceptional degradation capabilities as MB solution was degraded by 97% of its initial concentration within 45 min with good recyclability over 2 cycles. The exceptional photocatalytic efficacy of the catalyst can be attributed to various factors, including precise band alignment, Schottky barrier creation, and an extensive surface area.
