Description
Jiawei Li and co-authors turn titanium hydride into a catalyst that converts nitrate into ammonia with electric power. Making ammonia the green way could dodge the heat and pressure of the Haber-Bosch process, but nitrate reduction is slow and plagued by side reactions. Their 2024 paper builds the catalyst by electrochemically loading hydrogen into titanium fiber paper.
The hydride gave a large ammonia yield and near-total Faradaic efficiency at high current. Kinetic studies credit hydrogen that moves straight from the crystal lattice to the reaction site. A balance between lattice hydrogen and active hydrogen kept the catalyst stable as well. Energy chemists get a lattice-based design idea for cleaning nitrate while making a useful product.
