Comparison of adsorption and reactions of pyrrole on Cu(100) and O/Cu(100)

Mg–O–F Nanocomposite Catalysts Defend against Global Warming via the Efficient, Dynamic, and Rapid Capture of CO2 at Different Temperatures under Ambient Pressure

“…The total number of basic sites (sites·g –1 ) over each sample was measured by the TPD of pyrrole (99%-ACROS Organics, New Jersey, USA) as a probe molecule using TG and DSC techniques. The experimental details can be explained as follows: , 60 mg of each sample is preheated at 390 °C for 1 h in the air before the probe molecule is exposed. 20 ± 2 mg covered samples with pyrrole were subjected to thermogravimetric analysis (TGA) and another sample was subjected to DSC analyses at a heating rate of (10 °C·min –1 ) in a dry N 2 flow (40 mL·min –1 ), using a 50H Shimadzu thermal analyzer (Japan).…”

“…Numerous articles have studied the TPD technique of Others investigated the use of pyrrole as an IR spectroscopic molecular probe in a surface basicity determination of MgF 2 and metal oxides, 58,59 as well as employing pyrrole as an NMR probe molecule to determine the basic sites' strength over solid catalysts. 60 Very recently, Chen and his co-workers 33 proposed some possible intermediates of pyrrole due to its reactions with the O/Cu (100) surface, based on the TPD curves of pyrrole.…”
