Nitrogen-doped carbon black as methanol tolerant electrocatalyst for oxygen reduction reaction in direct methanol fuel cells

One-dimensional nitrogen-containing carbon nanostructures

“…Nitrogen-containing carbon (CN x , x<1) materials, e.g., N-containing carbon blacks [1,2], activated carbons [3][4][5], pyrolytic carbons [6], graphites [7][8][9], glass-like carbons [10,11], and carbon fibers [12], are one of the most extensively studied modified/functionalized carbon materials because of their unique physico-chemical properties and versatile applicability [13,14]. Their properties depend mostly on the type and content of different nitrogen functional groups.…”

Printing nanostructured carbon for energy storage and conversion applications

“…Nitrogen-doped carbon black and mesoporous carbon has already been demonstrated for fuel cell applications, where it exhibited similar oxygen reduction performance compared to in its undoped state [127,[135][136][137]. While there are myriad other carbon nanomaterials, studies of their suitability for printing has not yet been carried out.…”

“…The use of carbon black for methanol fuel cells [127] and for precious metal-free catalysts [128] has also been reported. Numerous studies have demonstrated its efficacy as a printable nanostructured carbon material for both inkjet [125,126,[129][130][131][132][133] and screen [134] printing of functional devices.…”

Synthesis of Nitrogen Doped Carbon and Its Enhanced Electrochemical Activity towards Ascorbic Acid Electrooxidation

“…Ndoped mesoporous carbon spheres have also been successfully fabricated by using melamine formaldehyde as the precursor [17]. NDC materials have been synthesized using polyaniline-carbon composites that revealed electrocatalytic 2 International Journal of Electrochemistry activity enhancement in oxygen reduction reaction [18]. Earlier attempts were reported [19,20] in converting the polyaniline into nitrogen containing carbon.…”
