Platinum with nano size 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 content of hydrogen in a solution at present: redox titration (MB-nano Pt colloidal solution titration). The principle is to catalyze hydrogen reduction of methylene blue (MB) by pcolloid Pt (nano platinum Pt). MB 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 MB, but under the catalysis of colloidal Pt, it can undergo a redox reaction with hydrogen of equal molecular weight, and the reaction can make the blue oxidized MB become the reduced methylene blue (leucoMB/leucomethylene blue): blue MB+2H⁺+2e^-=leucoMB

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