摘要：
The surface of an unpoisoned and sulfur-poisoned industrial iron ammonia catalysts is investigated by K, K+ thermal desorption. The K+ desorption energy increases while the K energy decreases upon poisoning. Presence of sulfur also suppresses the potassium desorption in electronically excited states.
