This patent details a new catalyst composed of an ordered intermetallic compound of platinum and germanium with the formula Pt3Ge.

The Pt3Ge is uniquely structured with a single crystallographic facet oriented in the 202 plane, designed specifically for catalyzing the hydrogen evolution reaction. Additionally, the patent covers the development of a catalyst ink, an electrode, an electrochemical cell, and related methods.

The newly described catalyst is noteworthy for its precise atomic configuration, which enhances its ability to facilitate the hydrogen evolution reaction. This process is crucial in various applications, particularly in renewable energy technologies like hydrogen fuel cells, which are seen as a cleaner alternative to fossil fuels.

The catalyst consists of an intermetallic compound of platinum and germanium, denoted by the chemical formula Pt3Ge. Its structural uniqueness lies in the orientation of its crystallographic facet, which is aligned in the 202 plane. This orientation is expected to optimize the surface interactions involved in the hydrogen evolution reaction, potentially increasing the efficiency and effectiveness of the process.

Alongside the catalyst itself, the patent outlines the creation of related materials and devices, including a catalyst ink that can be applied to various surfaces or components. The inclusion of electrodes and electrochemical cells suggests that the invention can be integrated into existing energy systems, offering a path to improve or innovate current hydrogen-based technologies.
