摘要: Abstract In this work, surface properties of wustite-based iron and iron‑cobalt catalysts were investigated. Measurements hydrogen temperature-programmed desorption (TPD-H2) area active forms conducted after reduction catalyst precursors (16 h) in pure at various temperatures (450, 475, 500, 550 600 °C). The amount cobalt the structure number adsorption sites relative to correlated with activity for ammonia synthesis reaction. presence increased thermal resistance same time their
