Multiwalled Carbon Nanotubes anode with low oxygen content for ascorbic acid fuel cells design

Enhanced dehydrogenation kinetics for ascorbic acid electrooxidation with ultra-low cell voltage and large current density

“…Various electrocatalysts have been explored for the AAOR, including precious metals [8,9,16], transition metals [17], molecular catalysts [18], and metal-free electrocatalysts [19]. Carbon materials have outstanding advantages owing to their wide availability, low cost, excellent catalytic activity, and high selectivity towards DHA [20]. Since it was realized that oxygen-containing groups (OCGs) on the carbon surface have a positive impact on the AAOR, numerous strategies have been developed to modify the OCGs, such as microwave treatment [21], acid etching [20], and DMF exfoliation [22].…”

However, the methods used to introduce OCGs are often energy-intensive and polluting.…”
