Platinum-iridium alloys are mixtures of the precious metals platinum and iridium from the platinum group.Platinum-iridium alloy, a platinum alloy containing iridium and used for jewellery and surgical pins.
Platinum-iridium is a readily worked alloy that is much harder, stiffer, and chemically resistant than pure platinum, which is relatively soft.
When compared to the soft pure platinum, platinum-iridium alloys are significantly tougher, stiffer, and more resistant to chemical attack. They are also easily worked metals.
The Global Platinum Iridium Alloy Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Composites of Platinum-Iridium Alloy Nanoparticles and Graphene Oxide for the DimethylAmine Borane (DMAB) dehydrogenation at ambient conditions.
The use of fossil fuel resources has several limitations, which has made it difficult for people to estimate the world’s future energy situation.
Finding alternative energy sources is now necessary for a sustainable environment. Hydrogen is currently being considered as a clean, renewable, and eco-friendly energy source. Unsolved is the issue of synthesis materials with high catalytic activity, safety, and storage capability.
Because of their high stability, hydrogen content, ease of use, and non-flammability, ammonia borane derivatives are chosen over other sources of hydrogen that include it, like ammonia borane.
Dimethylamine Borane (DMAB), a derivative of Ammonia Borane, has developed a keen interest in the use of hydrogen storage.Composites of platinum-iridium alloy nanoparticles and graphene oxide (PtIr@GO) for dimethylamine borane (DMAB) dehydrogenation, including their production, characterisation, catalytic, and computational research.
The PtIr@GO alloy nanoparticles were characterised using a variety of cutting-edge spectroscopic techniques, including X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Transmission Electron Microscopy (TEM), and high-resolution transmission electron microscopy. The prepared PtIr@GO nanocatalysts were created using an ethanol super-hydride method (HRTEM).
Also, experiments were conducted to test the catalytic activity, reusability, substrate concentration, and catalyst concentration of PtIr@GO alloy nanoparticles that were used to catalyse the dehydrogenation of DMAB.
The results showed that PtIr@GO NPs catalyst was still useful and active for the DMAB even under ambient settings. For the PtIr@GO cluster, DFT-B3LYP calculations have also been used to determine the prepared catalytic activity.
