Hydrogen production through low-temperature steam reforming of methane (LTSRM) has gained attention due to its potential for efficient and cost-effective hydrogen generation. Traditional processes using nickel-based catalysts at high temperatures are being replaced by low-temperature processes that offer benefits like quick start-up and reduced operational costs. Noble metal catalysts such as Ru, Rh, and Pt supported on Al2O3 have shown improved methane conversion and catalyst stability. Recent studies have focused on iridium-based catalysts supported on TiO2, demonstrating high activity in methane activation and steam reforming, paving the way for efficient low-temperature hydrogen production. Techniques like in situ XRD, TEM, Raman spectroscopy, and microkinetic simulations are utilized for catalyst characterization and understanding reaction mechanisms. The study highlights the importance of catalyst design and supports in enhancing hydrogen production efficiency and reducing environmental impact.
