摘要：
Oxygen and nitrogen complexes formation in coal char due to its reaction with NO at 100 degreesC in presence or absence of O-2 and/or H2O was studied by XPS. Fort-nation of -NO2 and pyridinic complexes and a considerable increment of oxygen complex was observed. The -NO2 complexes can be formed in all cases, even when there is no molecular oxygen present in the gas mixture. The presence of O-2 and/or H2O promotes their fort-nation. Apparently, this complex can be formed by the presence of C(O) complexes next to the site capable of chemisorbing NO. (C) 2002 Elsevier Science B.V. All rights reserved.
