Electrochemical Process: A new electrochemical process converts urea into percarbamide, enabling the treatment of urine in urban wastewater and transforming it into a useful resource.
o Pathway I: Urea reacts directly with hydrogen peroxide in the presence of a catalyst.
o Pathway II: Urea binds to a hydroperoxyl (-OOH) intermediate with H+ ions, forming percarbamide with catalyst support.
