Abstract—In current study, the Pd/SnO2 catalyst had been nanometer-sized SnO2 was mixed with an aqueous solution
prepared essfully by using precipitation method and its containing appropriate amount of PdCl2. The mixture was
characters were analyzed by XRD (X-ray diffraction), SEM stirred for 30 min in inert atmosphere and sequential drying at
(Transmission electron microscopy) and Specific surface area room temperature for 24h and at 120 ℃ for 2 h. then calcined
analyzer etc. The catalytic reduction of nitrate (100ppm) in ℃
deionized water was investigated in a batch reactor at room at 350 in ceramic furnace for 3 h. After that, the materials
temperature and atmospheric pressure, with formic acid (FA) were reduced by excess sodium borohydride solution at room
used as reducing agent. The results showed that nitrate could temperature for 30 min and dried at 100 ℃ for 2 h in vacuum
be pletely by Pd/SnO2 catalyst based on of drying oven. The catalysts obta
