Due to the limited biological degradation of dyes in conventional wastewater treatment plants, treating wastewater from the textile industry proves to be challenging. One option for water purification is the use of high-energy UV-C radiation, which can break down difficult-to-degrade organic compounds. However, this method is associated with very high energy costs. Alternatively, photocatalytic oxidation\u2014using titanium dioxide (TiO\u2082) as a catalyst\u2014presents a promising approach. TiO\u2082 can completely oxidize nearly all organic substances when exposed to UV-A radiation. Compared to the use of UV-C lamps, this process requires significantly less energy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The aim of the GMBU Department &#8220;Functional Coatings&#8221; was to develop photocatalytically active TiO\u2082 coatings through modifications in synthesis and deposition techniques, enabling the utilization of longer wavelengths of light, beyond UV-A, for photocatalytic activity. By modifying the TiO\u2082 coatings with silver (Ag) and nitrogen (N), the range of the light spectrum usable for photocatalytic activation was extended. This enabled the use of less energy-rich visible light range (> 400 nm, UV-vis) for dye degradation, effectively allowing sunlight to serve as an additional energy source. Materials such as glass fibers and highly porous ceramics were used as substrates for the photocatalytic coatings and were successfully implemented in pilot plants in Vietnam.<\/p>\n\n\n\n<div style=\"height:23px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-small-font-size wp-block-paragraph\">Project partners:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-small-font-size\">Institute for Research and Development of Natural Products (INAPRO) &#8211; Hanoi University of Science and Technology (HUST), Vietnam<\/li>\n\n\n\n<li class=\"has-small-font-size\">Institute of Materials Science and Max Bergmann Center for Biomaterials (MBZ) &#8211; Technical University of Dresden (TUD), Germany<\/li>\n\n\n\n<li class=\"has-small-font-size\">UMEX GmbH &#8211; Dresden, Germany<\/li>\n\n\n\n<li class=\"has-small-font-size\">GMBU e.V. &#8211; Department &#8220;Functional Coating&#8221; &#8211; Dresden, Germany<\/li>\n<\/ul>\n\n\n\n<div style=\"height:22px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-gmbu-primary-color has-alpha-channel-opacity has-gmbu-primary-background-color has-background is-style-wide\" \/>\n\n\n\n<div style=\"height:29px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-text-align-center has-gmbu-primary-color has-text-color has-link-color wp-elements-6cf1941a20ae45384428d77c8403d6d1 wp-block-paragraph\"><strong><span style=\"text-decoration: underline\">ANSPRECHPARTNER<\/span><\/strong>:<br><strong>Dr. Ulrich Soltmann<\/strong><br> Fachsektion Dresden &#8211; &#8220;Funktionelle Schichten&#8221;<br>Tel.: 0351 \/ 2695 343<br>E-Mail: soltmann@gmbu.de<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The German-Vietnamese research project &#8220;NaViTex&#8221; aimed to develop photocatalytic oxidation processes for wastewater treatment in the textile and garment industry, specifically designed for use in tropical regions.
