Collect the information about methods to study surface chemistry.

Following are the few methods that are employed to study surface chemistry.

i. X-ray photoelectron spectroscopy : 

It is a surface-sensitive spectroscopic technique which is used to measure elemental composition of the surface, to determine elements that are present as contaminants on the surface, etc.

ii. Auger electron spectroscopy : 

It is a common analytical technique which is used to study surfaces of materials.

iii. Temperature programmed desorption (TPD) :

Adsorbed molecules get desorbed when the surface temperature is increased. TPD technique is used to observe these desorbed molecules and helps in providing information about binding energy between the adsorbate and adsorbent.

iv. Scanning Electron Microscopy : 

In this technique, a scanning electron microscope is used to focus electron beam over the surface of the sample to be examined. The electron beam interacts with the sample and an image is obtained. This image provides information about surface structure and composition of the sample.
