Problems solved by technology

In 2004, the literature published by Wang et al. in "Surf.Interface Anal.36" also used X-ray photoelectric spectroscopy to study the stability of heated platinum cluster catalysts, and found that in the process of heating platinum cluster catalysts, the surface of platinum cluster catalysts It will slowly absorb iodine, resulting in the weakening of the effectiveness of the platinum cluster catalyst
Although the catalyst efficiency can be regenerated by reheating, this method requires heating up to 380°C, which is energy-intensive and not suitable for mass production

Embodiment 1

[0050] Embodiment 1: make the electrode containing catalyst layer and the solar cell with this electrode

[0051] [Making cathode / counter electrode]

[0052] Synthesis of polyvinylpyrrolidone (Poly(N-vinyl-2-pyrrolidone; PVP)-coated platinum nanoparticles was first dissolved in 44 milliliters (mL) of 0.1 grams (g) of PVP molecules (molecular weight (MW) = 8000) deionized water, and stirred at room temperature. Then add 0.2g of H2PtCl6 as a precursor to the previously prepared PVP solution, so the solution contains a ratio of polymer weight to precious metal weight of about 1.1. Then slowly add 5mL of reducing agent (0.5M NaBH4 solution). At this moment, the solution in the beaker will quickly change from light yellow to black, indicating that nano-scale platinum metal particles have been generated. The whole production process is carried out at room temperature and takes about 30 minutes.

[0053] In addition, a clean ITO glass plate (20Ω / □) was immersed in a bath containing ...

[0060] This example is to replicate the dye-sensitized solar cell provided in Example 1, except that when making the cathode, 0.5 g of PVP and 0.2 g of H2PtCl6 are used to prepare a PVP-coated platinum nanoparticle suspension.

Embodiment 3

[0061] Embodiment 3: make the electrode containing catalyst layer and the solar cell with this electrode

[0062] This example is to replicate the dye-sensitized solar cell provided in Example 1, except that when making the cathode, 2 g of PVP and 0.2 g of H2PtCl6 are used to prepare a PVP-coated platinum nanoparticle suspension.

Abstract

The invention discloses a method for forming electrodes containing catalyst layers. The method comprises the following steps: forming a conductive layer on the surface of a basal plate; conditioning the surface of the basal plate; soaking the basal plate in a second solution containing noble metals coated by macromolecules to form a noble metal catalyst layer on the surface of the basal plate; and thermally processing the noble metal catalyst layer at a temperature approximately lower than 300 DEG C in practice. The invention also discloses a method for manufacturing an electrochemical deviceby utilizing the electrodes.

Description

technical field [0001] The invention relates to a method for forming an electrode containing a catalyst layer, in particular to a method for forming an electrode by using polymer-coated noble metal particles to form a catalyst layer, and a method for manufacturing an electrochemical device with the electrode. Background technique [0002] Recently, due to the potential of Dye-sensitized solar cell (DSSC) to become a low-cost energy storage component, its development has gradually attracted attention. Traditionally, the anode (photoanode) of DSSC is a dye-sensitized nanocrystalline semiconductor layer deposited on indium tin oxide (Indium-tin oxide; ITO) or fluorine-doped tin oxide (Fluorine-doped tin oxide; FTO) glass; the cathode Platinum-plated counterelectrode is used. The electrolyte is generally a redox pair with iodine and triiodide ions in a suitable medium. figure 1 Describe the basic operation of DSSC, which can be summarized into the following five steps: (1) pho...
