Analytical methodologies using carbon substrates developed by pyrolysis

Abstract

As a viable alternative with respect to carbon-based materials prepared by vapor deposition, the pyrolysis of non-volatile organic precursors has allowed the fabrication of substrates with advantageous properties towards the development of analytical methodologies.

Fabrication of cotton textile waste-based magnetic activated carbon using FeCl3 activation by the Box–Behnken design: optimization and characteristics

“…62 Further weight loss emerged aer 400 C, the exothermic process reected the formation of solid phase carbide. 63 For FeCl 3 $6H 2 O, except for the evaporation of crystallization water from 0 C to 155 C, there were two major weight loss steps ($17% and $9.5%) occurring at 155-230 C and a weight loss ($11%) located in the range of 400-460 C for the FeCl 3 . According to the DSC spectrum of FeCl 3 , the process in the range of 155-460 C involved an endothermic reaction.…”

SU-8 based pyrolytic carbon for the electrochemical detection of dopamine

“…Under this category, SU-8 is one of the most commonly reported materials. 19 Pyrolysis results in nanographitic thin film materials. Large densities of edge-plane sites and oxygenated functionalities of PyC make it an ideal candidate for electrochemical sensor applications.…”

Carbonization of polymers of intrinsic microporosity to microporous heterocarbon: Capacitive pH measurements

“…Novel carbon and nano-carbon materials provide an impor-tant driving force for the development of new (electro-)analytical methodology and sensor devices [1]. Particularly exciting are the recent development of "nano-dot" carbons [2], functionalized nanoparticles [3], the use of grafting to provide surface modified carbon sensors [4], hyper-crosslinked porous carbons [5], and the pyrolytic formation of microporous carbon substrates for electroanalysis [6].…”

“…Pyrolysis of polymer precursors provides versatile access to both nonporous and porous electrode materials [6]. High quality sensor films can be produced for example from thin films of photo-resist polymer coatings [25,26].…”
