Dr. Lakshya Mathur’s Post

Delighted to share that our recent paper, titled "Efficient #hydrogen splitting via single atom catalysts supported on Zn12O12 nanocage for sustainable clean fuel production" has been published at the International Journal of Hydrogen Energy (Q1 Journal). Hydrogen, as a #renewable_energy source, offers numerous advantages such as high energy density, zero carbon dioxide emissions, lightweight properties, and non-toxicity, making it a promising candidate for future #energy_systems. In many industrial processes, #hydrogen_dissociation reactions play a crucial role. These reactions involve breaking down H2 molecules into reactive hydrogen atoms, which then bind with support materials or catalysts. This enables the storage of significant amounts of hydrogen at low temperatures and pressures. The primary objective of our study is to design first-row transition metals (Sc–Zn) doped zinc oxide (Zn12O12) and investigate their thermodynamic stability, electronic properties, and ability to facilitate hydrogen dissociation reactions through DFT simulations. For more details, the paper is attached.

I am thrilled to share our latest collaborative paper, published in the Journal of the American Chemical Society, detailing our innovative research at Brookhaven National Laboratory. This work focuses on advancing acid oxygen evolution reaction (OER) electrocatalysts, crucial for hydrogen production through water splitting—a key component in reducing greenhouse gases. Our team, comprising scientists from Brookhaven National Laboratory and Columbia University, has designed an innovative catalyst from the ground up. By leveraging theoretical calculations, we minimized the use of iridium, an expensive and scarce metal, while maximizing the catalyst's stability and activity in acidic conditions. This achievement is pivotal, considering the high costs and limited availability of iridium which previously hindered large-scale applications of iridium oxide (IrOx)-based electrocatalysts. Our catalyst demonstrated exceptional performance, requiring four times less iridium than commercially available options to produce hydrogen at an equivalent rate, or producing hydrogen four times faster for the same amount of iridium. This significant enhancement underscores the potential of our catalyst for industrial applications. This research exemplifies how theory-driven understanding at the atomic level can lead to practical catalyst designs, bringing us closer to real-world applications. The remaining challenge is scaling up production from milligrams to kilograms or tons to meet the demand for large-scale green hydrogen production. This research marks a promising step towards sustainable hydrogen production and a greener future. I am excited about the potential impacts of our findings and look forward to further developments in this field.

📰 A material has been modified for the solar-powered production of hydrogen from water decomposition in an experiment carried out in collaboration between two research centres supported by FAPESP. Agência FAPESP * - Research conducted by the Brazilian Centre for the Development of Functional Materials (CDMF) and the Centre for New Energy Innovation (CINE) has developed a new method of plasma treatment of thin films of antimony triselenide (Sb 2 Se 3 ) to make their surfaces hydrophilic, i.e., attracted to water molecules and easily dissolved by water, rather than hydrophobic (repelled by water). The material has properties that enable it to be used as a photocathode to produce hydrogen by a solar-powered water decomposition method. The hydrophobic surface of antimony triselenide impairs its performance in photoelectrochemical cells, reducing its ability to convert light (solar energy) into chemical energy. The production of hydrogen from solar energy is important because hydrogen is a strong candidate for power generation in automobiles and other areas. #semiconductor #CDMF #CINE #FAPESP #solarenergy #hydrogen #powergeneration #chips
