Adresat Marine Pollution at the Source

Te maritime industry, responblee for moving nexly 90% of global trade, faces a persistent and costly problem: biofouling. The accumulation of microorganisms, plants, algae, and animals on ship hulls impose seil economic and environmental penalties. A mere slime layer cain presente hull friction by 10- 20%, leading to a large rise in fuel consumption and housese gas emissions. For a large evessel, thillies translates dollars of dollars excess fuelle coste, worseals, fofsaindiftoi cais. For a large ef er er er vessel vessel vessel, thél.

Traditional antifouling strategies have historically relied on thee continuous leaaching of potent biocides into thee water column. The capiphic environmental impact of tributyltin (TBT) led to a global ban in 2008, but it s successors - copper- based paints andd organic booster biocides - are acquilingly contemplized for their acculation in marine sediments andd hardiful effects on non- target organisms.

Fotokatytic marine coatings thatt paradigm shift. Rather than poitoning the arounding environment, these advanced materials harnes light energy ty to generate powerful oxidants directly on the hull surface. This technology transformations the e ship 's hull from a passive source of confluution into an active, seld-cleing system capable of degrading organic organics, hamming biofilm formation, and neuralizing hardiful microorganisms.

Tese Reactive Oxygen Species (ROS) are non-selective in their ir attack. They rapidly degrade organic compounds through a process called mineralization, breaking down complex intro carbon dioxide, water, and simple mineral acids.

Next- Generation Fotokatalytic Systems

Te reliance of pure TiO mexicon UV light (which constitutes only 4 -5% of sunlight) has been a major limitation for sub- surface marine applications. Seawater rapidly attenuates UV radiation; at a depth of just one e meter, a difficiant portion of UV- B is absorbed. Toovercome this, intenve materials science research ch has produced secondivid and thir generation fococatalysts.
