As global warming and climate change caused by fossil fuel grew to be a public concern, find a clean and sustainable substitute energy had become a scientific hotspot. Urea is a hydrogen carrier which makes it a feasible energy source. The urea-rich wastewater or urine which normally contains 0.33 M urea were used as fuels, which can generate electricity while processing wastewater to reduce water pollution and others. Moreover, It is considered to have a great application in aerospace to recycle the urine produced by astronauts.
