摘 要：Recovering waste heat from fuel energy supply is a haunting challenge for greatly reducing the emissions of greenhouse gas CO2,and achieving sustainable ***,a significant amount of energy is dissipated to environment as low-grade heat （below 250~oC）,largely produced in transportation and chemical engineering *** accounts for～30%of the total global energy products but is much more difficult to recycle than high-grade heat （Figure 1 A）[1].So the reuse of low-grade heat is of great importance for the future energy demands and the issue of climate change[2,3].So far,several technologies have been developed to recover low-grade waste heat,such as organic Rankine cycle,water desalination,piezoelectric,and thermoelectric conversion[4].
