Using micromotors to treat water and generate green energy

Researchers at the Institute of Chemical Research of Catalonia in Spain have developed autonomous micromotors for wastewater purification. The micromotors, made from a silicon and manganese dioxide tube, release bubbles from one end setting the tube in motion. Covered with the enzyme laccase, the micromotors accelerate the conversion of urea in polluted water into ammonia, which can be extracted and converted into hydrogen, offering potential as a green energy source. An AI method from the University of Gothenburg is in use to optimise the micromotor design. The micromotors could enhance water treatment, addressing eutrophication issues, and potentially produce green energy from extracted ammonia. (University of Gothenburg)
