CATALYST WITH SUPPORTED PLATINUM-GROUP METAL PROCESS FOR PRODUCING WATER IN WHICH HYDROGEN PEROXIDE HAS BEEN DECOMPOSED PROCESS FOR PRODUCING WATER FROM WHICH DISSOLVED OXYGEN HAS BEEN REMOVED AND METHOD OF CLEANING ELECTRONIC PART

摘要

The macropores in the bubble form overlap each other and the overlapping portions become openings having an average diameter of 30 to 300 in the water wet state. The continuous macropores are 0.5 to 5 ml / g of the total pore volume, The anion exchanger is uniformly distributed in the organic porous anion exchanger, and in the SEM image of the cut surface of the continuous macropore structure (dried body), anion exchange capacity per volume of 0.4 to 1.0 mg equivalent / The platinum group metal nanoparticles having an average particle diameter of 1 to 100 nm are supported on the organic porous anion exchanger having a skeleton area of 25 to 50% of the image area on the cross section in an amount of 0.004 to 20 wt% Metal supported catalyst. According to the present invention, when the SV is 2000h^-One, It is possible to provide a high performance catalyst capable of decomposing hydrogen peroxide or removing dissolved oxygen even when the height of the packed bed of the catalyst is made thinner.;
