my country has made new breakthroughs in methanol catalysis research, and methanol fuel cells will have very good application potential in the field of new energy.
Recently, Li Yue's research group, a researcher at the Micro-Nano Technology and Device Laboratory of the Institute of Solid State Physics, Hefei Institute of Physical Sciences, Chinese Academy of Sciences, has made new progress in the controllable preparation of porous gold-silver-platinum (AuAgpt) alloy nanomaterials and its research on methanol catalysis. .
In recent years, with the rapid economic development, my country's demand for energy is increasing. Fossil energy, as the most important energy consumed globally, not only brings convenience to us, but also causes serious pollution to the global environment. Therefore, it is becoming increasingly important to develop clean energy that can replace fossil energy. A fuel cell is a device that can directly convert chemical energy in fuel and oxidant into electrical energy. It is the fourth power generation method after hydraulic, thermal, and atomic power generation. It is energy-saving, high conversion efficiency, and close to zero emissions. advantages; it has become an important way to solve energy and environmental problems. Among them, methanol fuel cells are widely used in portable devices due to their high efficiency and environmental friendliness. Compared with hydrogen energy, methanol is a cheaper liquid fuel that is easy to store and transport, and has a higher theoretical energy density. Therefore, methanol fuel cells have very good application potential in the field of new energy.
At present, the catalysts of methanol fuel cells are mainly made of platinum nanomaterials. However, during the preparation process of traditional platinum nanomaterials, side effects such as poisoning and precipitation will occur, which gradually reduces the effective area activity and mass activity of platinum nanocatalysts, seriously affecting the Methanol fuel cell service life. In addition, the storage amount of metal platinum required to prepare platinum nanomaterials is low, expensive and costly, which is very unfavorable for large-scale commercial application of batteries. In order to improve the catalytic activity and stability of methanol fuel cell catalysts, platinum and platinum-based nanocatalysts with different structures have been prepared through multiple methods, such as: platinum nanoparticles with high-index crystal planes, hollow platinum-palladium alloys, platinum-based nanocatalysts, etc. Nickel alloys, silver-platinum alloys, etc. However, most of the preparation methods of these materials have complex processes and long reaction cycles, and cannot well solve the above-mentioned catalytic activity and stability problems.
