Detailed introduction

Platinum group metals are known to have high electrical activation, platinum electrode electrolysis oxygen evolution of water can better produce hydrogen molecules, thus achieving high concentration of hydrogen water, water electrolysis, the electrode reaction formula is as follows.In acidic solution, the cathode reaction: 4H++4e-=2H2, ∏=0V, the anodic reaction: 2 H2O-4e-=4H++O2, ∏=1.23 V, alkaline solution, the cathodic reaction: 2H2O+4e-=2H2+4OH-, ∏=0.828V, the anodic reaction: 4OH--4e-=2H2O+O2,∏=0.401V

From the above equation, it can be seen that the total reaction of hydrolyzation is as follows, whether in acidic or alkaline solutions.2H2O=2H2+O2, the theoretical decomposition voltage of water is independent of pH value, and the selection of good electrodes is crucial.

Advantages of coated titanium electrodes:

1.The size of the anode is stable and the distance between electrodes does not change during the electrolysis process, so the electrolysis operation can be carried out under the condition of stable tank voltage.

2.Low working voltage, small power consumption, DC power consumption can be reduced by 10-20%.

3.Titanium anode has long working life and strong corrosion resistance.

4.The dissolution of graphite anode and lead anode can be overcome and the pollution of electrolyte and cathode products can be avoided.

5.High current density, low overpotential, high catalytic activity of electrode, and high production efficiency.

6.Titanium anode is used in chlor-alkali production, with high product quality, high chlorine gas purity, no CO2 and high alkali concentration, which can save heating steam and energy consumption.

7.It can avoid the short circuit of lead anode after deformation and improve the current efficiency.

8.Easy to make and high precision.

9. The titanium matrix can be reused.

10.Low overpotential characteristic, the surface between electrodes and the bubbles of electrodes are easy to be removed, which can effectively reduce the voltage of electrolytic cell
