The Vietnamese doctor breeds an alternative to platinum

Dr. Dao Van Duong (Phenikaa University) synthesized hybrid materials with high conversion efficiency, 20% cheaper price than platinum in conventional batteries.

As one of 5 Vietnamese scientists in the top of global reviewers in 2019,  Dr. Dao Van Duong (36 years old) is highly appreciated for pursuing integrated studies of hybrid materials with effects. Resonance and properties superior to the platinum material in batteries for the purpose of reducing costs for users.

This hybrid material is a combination of Nio blade and nanoparticles , has a large surface area with high porosity, large catalytic capacity, reducing reaction at the opposite electrode and increasing the efficiency of optical cells. electricity. This material has a high conversion efficiency (8.2%) compared to 8.8% of platinum devices.

From the initial results, he created a battery containing Nio hybrid materials , which is 20% cheaper than conventional ones, with an average life expectancy of 30%. Conventional batteries use two electrodes made of conductive metal, platinum and graphite, in which platinum catalysts must be imported from abroad, resulting in higher fuel prices and durability. inferior and toxic. The research results are published in the international energy journal Journal of Power Source and Nano Energy.

Dr. Duong said, to be able to optimize the outstanding characteristics from Nio materials, the research team needs more time for further research. When successful, the material can be applied in lighting systems in hospitals, serving agricultural production.

He currently has more than 90 articles published in international journals (with 80 under ISI Q1), 6 patents. In 2019, he reached the top 100,000 leading researchers in the world through scientific quotes and scientific quantitative indicators from the Scopus database (analysis data in 2017).

Starting research on hybrid materials and renewable energy in 2013 as a Professor at Chungnam National University (Korea), in 2019, Dr. Duong returned to Vietnam with the task of leading the research team. strong "conversion and storage of renewable energy" at Phenikaa University.

1. The new material is proven to reach the limit of hardness, being extremely light
2. Successful fabrication of durable glass, but made from wood
