Embodiment 1
[0037] A preparation method of a flower-shaped palladium hydride catalyst for catalyzing an oxygen reduction reaction, said method comprising the steps of:
[0038] 1) Take 10 mg of sodium chloropalladate and 30 mg of tungsten hexacarbonyl, and then add 8 mL of N,N-dimethylformamide solution. After the solution is fully mixed, add 2 mL of acetic acid solution; the solution is fully mixed Afterwards, place it in an oil bath and heat it to 140°C. After reacting for 2 hours, wash, centrifuge, and dry to obtain flower-shaped palladium.
[0039] 2) Take the flower-shaped palladium with a mass of 4mg, add 20mL of N,N-dimethylformamide solution, mix well, put it in an oil bath and heat it to 160°C, and react for 16h After washing, centrifuging and drying, the flower-like palladium hydride redox catalyst is obtained.
[0040] The SEM figure of the flower-shaped palladium hydride that obtains sees figure 1 . The TEM figure of the flower-shaped palladium hydride obtained is shown in ...
Embodiment 2
[0043] A kind of preparation method of the spongy palladium hydride alloy catalyst of catalytic oxygen reduction reaction, described method comprises the steps:
[0044] 1) Take 1 mg of sodium chloropalladate and 1 mg of tungsten hexacarbonyl, and then add 1 mL of N,N-dimethylformamide solution. After the solution is fully mixed, add 1 mL of acetic acid solution; the solution is fully mixed Afterwards, place it in an oil bath and heat it to 50°C, react for 1 hour, wash, centrifuge, and dry to obtain palladium hydride in the form of sponge.
[0045] 2) Take the prepared sponge-like palladium hydride with a mass of 4mg, add 1mL of N,N-dimethylformamide solution, mix well, place in an oil bath and heat to 50°C, and react After 1 h, wash, centrifuge, and dry to obtain a spongy palladium hydride oxygen reduction catalyst.
[0046] The SEM figure of the spongy palladium hydride obtained is referring to Figure 8 , to obtain linear sweep voltammetry at 1600 rpm, mass activity and a...
Embodiment 3
[0049] A preparation method of a flower-shaped palladium hydride catalyst for catalyzing an oxygen reduction reaction, said method comprising the steps of:
[0050] 1) Take 50mg of sodium chloropalladate and 50mg of tungsten hexacarbonyl, respectively, and then add 20mL of N,N-dimethylformamide solution. After the solution is fully mixed, add between 10mL of acetic acid solution; the solution is fully After mixing, place in an oil bath and heat to 200°C, react for 10 hours, wash, centrifuge, and dry to obtain the product.
[0051] 2) Take the prepared product with a mass of 10mg, add 50mL of N,N-dimethylformamide solution, mix well, put it in an oil bath and heat it to 200°C, and react for 30h, Wash, centrifuge and dry to obtain the catalyst.
[0052] Because in this process, the mass of sodium chloropalladate and tungsten hexacarbonyl is relatively large, the size of the catalyst synthesized is also relatively large; in addition, after increasing the amount of acetic acid, t...
