Contact-electro-catalysis (CEC) has emerged as a novel approach for catalyzing redox reactions. However, there is still significant room enhancing the catalytic efficiency of CEC. Here, an organic degradation device that combines water atomization and CEC based on gas-liquid two-phase flow-based triboelectric nanogenerator (GL-TENG) was designed. When using 8 mg/L crystal violet (CV) target dye airflow velocity reaches 30 m/s, rate constant k high 73.15 min-1, significantly exceeding existing contact electrocatalytic efficiencies. The impact concentration output performance GL-TENG investigated. It shows good linear relationship between signal GL-TENG. Real-time monitoring can be achieved located at end tube. These experimental results not only offer ultrafast method degrading dyes but also provide new insights into interactions solutions solid surfaces.

Contact-electro-catalysis (CEC) has emerged as a promising catalytic methodology, integrating principles from solid-liquid triboelectric nanogenerators (SL-TENGs) into catalysis. Unlike conventional approaches, CEC harnesses various forms of mechanical energy, including wind and water, along with other renewable sources, enabling reactions under natural conditions without reliance on specific energy inputs like light or electricity. This review presents the basic discusses its applications, degradation organic molecules, synthesis chemical substances, reduction metals. Furthermore, it explores methods to improve efficiency by optimizing conditions, structure catalyst materials, start-up mode. The concluding section offers insights future prospects potential applications CEC, highlighting role in advancing sustainable technologies.

Metallic superhydrophobic surfaces often encounter several challenges, including poor durability, limited functionality, and difficulties in application to complex curved structures. Therefore, we propose a novel strategy for surface biomimetic interpenetrating phase composites (S-BIPC). This approach employs laser powder bed fusion (LPBF) technology create microstructures as the primary on Ti6Al4V single step. Subsequently, functional nanofillers synthesized via sol-gel method serve secondary phase, with form heterogeneous (BHS). The interaction among these materials endows BHS exceptional allowing it retain superhydrophobicity after at least 5000 cycles of sandpaper abrasion approximately 200% compressive strain. Furthermore, exhibits self-cleaning properties, wear resistance, corrosion anti-icing capabilities, can be applied structures, making S-BIPC one most promising candidates metallic surfaces.
