About this program:

Surface and interfacial chemistry examine the chemical processes that occur at the phase boundary between solid/ solid liquid/ solid, liquid/ liquid and gas/ solid interfaces. Surface chemistry branch conduct experiments to study the surface of a solid/ liquid and their interfaces before, during and after reaction. The understanding is used to develop new or improved surfaces, coatings and materials for different application. Research program includes modifying surface to reduce corrosion, understanding dynamics on surfaces as they pertain to film deposition, nanomaterial synthesis, adsorption and catalysis.

Objectives

Develop different oxide material with high surface area through different technique like hydrothermal, sol-gel and reverse microemulsion etc

 New technique development for the synthesis of oxide nanomaterials with uniform size and variable surface properties. Material modification to improve the surface properties so that the material can be used as coating, adsorbent and catalyst.

Development of hydrophilic, hydrophobic, self cleaning and corrosion resistant oxide coating on metal/glass surfaces through sol-gel technique.

  • Facility for BET surface area, pore size, average pore diameter and pore volume analysis. Detail surface functional group and chemical environment of the element in a material can be characterized using available facilities like FTIR, Raman spectroscopy and XPS at NML.

Major Developments  

High surface area oxide materials like TiO2, Al2O3 and mixed oxides

Nitrogen doped titania-zirconia binary oxide with high surface area and enhanced photocatalytic activity

Different thermally stable transition metal oxide pillared clays  for use as adsorbent and catalysts

Stable, nontoxic nanosilver and gold dispersion in aqueous solution 

Development of corrosion resistant oxide coating on SS and mild steel material

 Major Facilities

(i) BET Surface area and pore size analyzer, (ii)  FTIR spectroscopy, (iii) UV-visible Spectroscopy with defused reflectance facility, (iv) Ultrasonic processor for synthesis, (v) Nanoparticle size analyzer, (vi) Contact angle meter and (vii) X-ray photoelectron spectroscopy (XPS)
