Study on Preparation of Nano-granular Pr6O11 by Thermal Decomposition and its Optical Absorption Properties AITranslate
Abstract AITranslate
The nano-granular Pr6O11 was prepared by thermal decomposition using Pr2(C2O4)3·6 H2O as the praseodymium source.The thermal decomposition process of Pr2(C2O4)3·6 H2O in air was studied by TG-DTA curves.The phases,morphologies and optical absorption properties of the thermal decomposition products of Pr2(C2O4)3·6 H2O in air were characterized by XRD,SEM and UV-Vis spectrophotometer,respectively.The results show that there are two main stages in the thermal decomposition process of Pr2(C2O4)3·6 H2O in air.The first stage is room temperature^300 ℃,and large flake-like Pr2(C2O4)3·6 H2O loses its adsorption water and crystal water to turn into small flake-like Pr2(C2O4)3.The second stage is 300~800 ℃,and small flake-like Pr2(C2O4)3 is thermally decomposed into small flaky Pr6O11.Nano-granular Pr6O11 is obtained by heat preservation at 900 ℃ for 10 min,and its absorption ability for visible light is significantly better than that of small flaky Pr6O11.
