dc.descriptionAbstract: This manuscript proposes to valorize the macauba endocarp (E) wastes from the macauba processing by a pyrolytic + hydrothermal process to produce activated carbon (ACE), followed by chemical treatment with H2O2 (ACEA) and HNO3 (ACEB). Elemental analysis, surface area, pore-size distribution, and surface functional groups are investigated for the different prepared materials. ACEA and ACEB offer a higher surface area and functionality than Vulcan XC-72R (VC), making them suitable as carbon supports for Pd nanoparticles. The prepared Pd/ACEA and Pd/ACEB are physicochemically characterized by X-ray diffraction and Transmission Electron Microscopy. Their electrochemical performance is initially evaluated in a 3-electrode glass cell and is found to surpass that of Pd/VC in glycerol electro-oxidation. This trend is confirmed in the glycerol acid-alkaline electroreformer, where hydrogen and electricity were simultaneously produced, achieving a maximum power density of 0.28 kW m−2 and H2 flux of 0.6 STP m3 m−2 h−1 at 80 °C.
