A analysis crew from UNIST has unveiled a novel know-how able to extracting hydrogen (H₂) saved in ammonia (NH₃) by including silicon (Si), concurrently producing high-purity H2 and silicon nitride (Si₃N₄). This revolutionary course of not solely reduces hydrogen manufacturing prices, but additionally allows the recycling of silicon from waste photo voltaic panels, attracting important consideration as a sustainable answer.
Led by Professor Jong-Beom Baek within the Faculty of Vitality and Chemical Engineering at UNIST, the analysis crew developed a ball milling course of that may produce 100% pure H₂ immediately from NH₃ at low temperatures.
Their paper, “Separation-Free High-Purity Hydrogen Production via the Mechanochemical Ammonia–Silicon Reaction under Mild Conditions” was revealed within the September 2025 version of the Journal of the American Chemical Society.
NH3 is considered a promising clear gas service due to its excessive H₂ content material (17.6 wt%) and well-established infrastructure for storage and transport. Nevertheless, typical strategies to launch H₂ from ammonia require excessive temperatures (400–600°C) and extra purification steps, resulting in elevated power consumption and prices.
The newly developed course of operates at a remarkably…
