Industrial processes of the production of tin containers for food packaging, precious metal extraction, remediation of industrial wastewaters and contaminated soils and hydrogen fuel generation from renewable energy sources require a chemically stable/environmentally-friendly material able to oxidize the water and organic pollutants with low energy consumption. These processes employ titanium anodes with an active and expensive coating of precious metal oxides of limited service life. Upon degradation, the anodes are to be disposed as process waste or the anode coating should be repaired externally with high costs. A novel anode production/renewal procedure will be investigated, involving defined hydrothermal synthesis of less-expensive oxides to prepare uniform coatings of extended service lives. Investigation should result in optimized easy-to-use methodology for in-site procedure for the reparation of waste anodes of improved service characteristics. The results will impact the reduction of industrial wastes, sustainable energy consumption and production, as well as production costs in food industry, metallurgy and corrosion protection, with simultaneous self-sustainable progress toward clean technologies in heavy industry.
