Here, we prepared a series of Pt supported on carbon nanofiber catalysts which vary intheir Pt particle size and the content of oxygen groups on the surface of the CNF. We show that the activity ofthese catalysts for electrocatalytic glucose oxidation relates linearly with the content of support oxygen groups.Since the electronic state of Pt (XAS) and Pt surface structure (CO-stripping) were indistinguishable for allmaterials, we conclude that sorption effects of glucose play a crucial role in catalytic activity. This was furtherconfirmed by establishing a relation between the annulus of the Pt particles and the activity PB Elsevier SN 0926-3373 YR 2023 FD 2023 LK http://hdl.handle.net/10498/31411 UL http://hdl.handle.net/10498/31411 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 13-nov-2026
