They focus on high temperature gas-solid reactions where solids volatilize and condense and lose or gain volatile components, and where heterogeneous chemisorption reactions occur between gases and solid surfaces.
Further, adsorption is divided into chemical adsorption (or chemisorption) and physical adsorption (or physisorption).
The literature also suggest a mechanism for which the adsorption of transitional metals on these kind of surfaces, through the formation of a covalent bond between the metal ion and the oxidic surface, called chemisorption, according to equation (2) where M could be any transitional metal.
The Pseudo secord-order kinetic model assumes that chemisorption is the rate determining step.
The objective of his research was to report a new method, which would involve the chemisorption and the subsequent NaBH4 reduction of Au(III) complex ions on TiO2-Pt (TiO2-Pt: Pt nanoparticles deposited TiO2).
This behavior supported the assumption behind the model that the adsorption is due to chemisorption. The rate controlling step underlying chemisorption involved the electronic interaction between the MG dye molecules and the adsorbent IPN surface.
The approach reported in this article is to modify conventional zeolite with active metal sites so that the adsorbing molecules are more strongly bound to the zeolite surface (chemisorption), resulting in a higher release temperature [12, 13, 14, 15].
Then, silver nanoparticles undergo chemisorption so that the silver nanoparticles fuse to each other and form wiring.
Pseudo second order kinetics by Ho and McKay [33], which describes the adsorption process for all concentration and may as well, describes chemisorption process.
The hydrogen is produced from the clean sources such as solar energy and water, it has to be stored by physiorption or chemisorption processes on to the solid state systems.
The adsorption on ammonia on the surface can be divided into two categories: physisorption and chemisorption. Bannov et al.
