it has been paid much attention because of its great advantages in energy conservation and environmental protection.[1-3] LiBr/H2O is generally used as the working fluid of absorption system because of its favorable thermophysical properties. However, as a traditional working fluid, LiBr/H2O has strong corrosivity to common metal materials and even corrosion resistant alloys, which not only reduces the life of absorption system, but also worsens the vacuum and the performance due to producing hydrogen and solid corrosion product.[4-10] These adverse effects restrain the applications of high-temperature absorption heat pump, such as the absorption heat transformer and triple-effect absorption refrigeration system
