Embodiment 1
[0059] A PdNiW / C ternary alloy nano catalyst is a PdNiW / C ternary alloy nano catalyst formed with Pd, Ni and W as active centers and XC-72 activated carbon as a carrier;
[0060] The amount of the active center of the PdNiW / C ternary alloy nanocatalyst and the carrier XC-72 activated carbon is calculated according to the mass ratio, that is, the quality of the XC-72 activated carbon: the total mass of Pd, Ni and W is 4:1;
[0061] In the active center of the PdNiW / C ternary alloy nanocatalyst, calculated by molar ratio, Pd:Ni:W is 7:2:1.
[0062] The preparation method of above-mentioned a kind of PdNiW / C ternary alloy nano-catalyst, concrete steps are as follows:
[0063] (1), 11.86mgPdCl 2 Dissolve in 50ml ethylene glycol solution, ultrasonic for 1h to form solution 1;
[0064] (2), add 0.5g L successively to the solution 1 formed in step (1) -1 NiCl 2 ·6H 2 O in ethylene glycol solution 9.1ml, 1g L -1 Na 2 WO 4 2.8ml of ethylene glycol solution, adjust the pH value ...
