Nano Platinum for Hydrogen Content Determination

Nano Platinum for Hydrogen Content Determination

Specification of HONGWU's Nano Platinum:

MF: Pt

Form: powder or customized dispersion(collodial)

Particle size: <20nm 

Breif introduction of platinum nano material: As a functional material, nano Pt material has important application value in the fields of catalysis, sensors, fuel cells, optics, electronics and electromagnetism.

Key step to achieve good properties: according to the specific field of platinum for catalyst application, choose suitable dispersing agent and stabilizer to maximize the catalytic efficiency of nano-platinum.

Platnium(Pt) nano used in titrant for determining the content of hydrogen:

Nano size platinum is used to prepare the titrant. Usually, this platinum nano colloid solution has platinum nanoparticles with fine particle size, high concentration and good catalytic performance, which can effectively improve the accuracy and efficiency of hydrogen determination.

One of the most convenient and quick methods for determining the hydrogen content in a solution at present: redox titration (methylene blue-nano platinum colloidal solution titration). The principle is to catalyze hydrogen reduction of methylene blue (MB) by colloidal platinum (nano platinum Pt). Methylene blue is a commonly used dye and redox titration indicator. Due to the influence of the covalent bond of hydrogen itself, it is difficult for hydrogen to react with methylene blue, but under the catalysis of colloidal platinum, it can undergo a redox reaction with hydrogen of equal molecular weight, and the reaction can make the blue oxidized methylene blue become the reduced methylene blue (leucoMB/leucomethylene blue): blue MB+2H⁺+2e^-=leucoMB
