Description
María Rosario Sánchez-Macías and co-authors turned metal waste into a sunlight-powered cleaner in a 2026 study. Sulfate-eating bacteria in a sludge reactor produced sulfide that pulled mixed metal sulfides out of metallurgical wastewater. The recovered material was mostly antimony sulfide with bismuth phases, in a fibrous form that absorbs sunlight well. The team tested it against Rhodamine B, a bright pink dye used as a model pollutant.
Under sunlight, the waste-born catalyst broke down over 98 percent of the dye under the test conditions. It beat pure reagent-grade antimony sulfide, reacting more than five times faster at its best. Early reuse checks followed. The work shows a double win: cleaning metal wastewater and gaining a cheap catalyst that cleans dyed water.
