Intercalation vanadium pentoxide

A colloidal suspension of conductive vanadium pentoxide [130] can be used to perform intercalation, adsorption or encapsulation of electroactive molecules or biomolecules for electrodes or biosensor realization [131]. Encapsulation of glucose oxidase in nanocomposite films made with polyvinyl alcohol and V205 sol-gel matrix or in ferrocene intercalated V2Os sol-gel [132] were envisaged to prepare glucose biosensors. 

Vanadium pentoxide has been investigated for 30 years ° ° it has a layered structure with weak vanadium—oxygen bonds between the layers and is now known to react by an intercalation mechanism 40,85 + V2O5 = LLV2O5.

Vanadium pentoxide xerogels are very reactive layered host materials which can be intercalated by various means such as cation-exchange, acid-base chemistry, or redox reactions. Vanadium pentoxide xerogel was prepared by polymerization of HVO3 after a few days of reaction at room temperature. The resultant xerogel...

Remarkably, a large number of electronically conducting intercalation hosts are accessible today, including numerous transition-metal oxides with framework lattices, such as vanadium pentoxide and nickel oxide, and organic solids with molecular lattices. Additionally, a large variety of ionic guest species have been studied. 

Orthorhombic crystalline vanadium pentoxide is a typical intercalation compound as a result of its layered structure, see Fig. 5.2, which finds widespread use in lithium ion intercalation applications such as electrochromic cells [17], high energy density batteries [18], supercapacitors [19], and sensors [20], since it offers the essential advantages of low cost, abundant availability, easy synthesis, and high intercalation densities [15, 16]. 

In 1975, Whittingham was first to report the reversible electrochemical lithium intercalation into vanadium pentoxide [11]. V2O5 electrodes are expected to undergo lithium ion insertion accompanied by several structural modifications, occurring in several consecutive stages [21, 22]...
