Chemisorption: Properties, Reactions and Uses opens by presenting chemisorption analysis by a pulse flow system for determining the metal nanosize for different heterogeneous catalysts. The authors show some examples of palladium, nickel, platinum, copper and gold nanoparticles supported on different supports, and discuss potentialities, criticalities and applicability of the technique.
Following this, the synthesis of titanium oxide coatings on a high-porosity silicas surface with a regular pore structure was studied using a thermogravimetric setup with a McBain balance and atomic force microscopy. The kinetic dependences of chemisorption processes used in the molecular layering method were determined, and the difference in flow mechanisms and results of coating synthesis on meso- and microporous silicas are presented.
The salt-ammonia chemisorption cycle has been extensively developed in many fields such as low-grade heat driven refrigeration, heat pump, thermal storage and power generation. As such, the kinetic models of salt-ammonia chemisorption were reviewed and discussed in this work, and the values of kinetic parameters in different models were summarized and listed for ammonia chemisorption.
In the concluding study, heterophase textured films of vanadium dioxide on single-crystal silicon substrates have been synthesized by the sol–gel method from solutions of triethoxyvanadyl VO(OEt)3 in methyl cellosolve CH3OCH2CH2OH. The effect of ozone and ethanol vapor chemisorption on the parameters of the semiconductor–metal phase transition in vanadium dioxide VO2(B) are also studied.
