American chemists have recently developed a catalyst that can lift hydrogen fuel from urine. This kind of catalyst not only can drive the future hydrogen fuel automobile, but also help to deal with municipal sewage.
Challadian Portmeyer of Ohio University used electrolysis to separate hydrogen from the world's most abundant waste, such as urine. Compared to dividing hydrogen atoms from water, the cost of this type of system is much lower.
The important component of urine is urea. Each urea molecule contains four hydrogen atoms. It is important that they are not so closely connected to the hydrogen atoms in the water molecule.
Porter's method is to electrolytically smash the molecular layout, manipulate a cheap new nickel-based electrode, and selectively oxidize urea molecules. The urea molecular layout requires 0.37 volts, while the split water molecule requires 1.23 volts.
Porter thought that the craft was convenient for large-scale range maneuvers and could also be used to treat sewage. She said: "There is no need to reform the car. At the moment, the operation of the electrolytic cell is very widespread."
