Ultra-low casting of Pt based nano-ink for electrooxidation of glycerol and ethylene glycol fuels in alkaline medium

Tailor‐Designed Porous Catalysts: Nickel‐Doped Cu/Cu2O Foams for Efficient Glycerol Electro‐Oxidation

“…However, it is toxic and a crossover problem through the membrane diminishes the efficiency of the fuel cell with time. Other alcohols, e. g., ethanol, have been used as promising non‐toxic alternatives with higher energy density compared to methanol (8.01 kW h kg −1 vs. 6.09 kW h kg −1 ), but the difficulty of the C−C bond breaking (for complete ethanol oxidation at low temperature) is a severe drawback . In this context, polyols, e. g., glycerol, seem to be promising alternatives owing to its unique features such as low flammability and volatility, non‐toxicity, low crossover flux through the membrane and bio‐renewability .…”

“…Other alcohols, e. g., ethanol, have been used as promising non-toxic alternatives with higher energy density compared to methanol (8.01 kW h kg À 1 vs. 6.09 kW h kg À 1 ), [14] but the difficulty of the CÀ C bond breaking (for complete ethanol oxidation at low temperature) is a severe drawback. [14] In this context, polyols, e. g., glycerol, seem to be promising alternatives owing to its unique features such as low flammability and volatility, nontoxicity, low crossover flux through the membrane and biorenewability. [15][16][17][18][19] Additionally, from the economic and environmental point of view, glycerol is produced in large amounts as a byproduct during the biodiesel production process.…”

Recent advances in glycerol valorization via electrooxidation: Catalyst, mechanism and device

“…The incorporation of carbonized 1,10-phenanthroline moiety created the strong metal-support interactions between the amorphous Pt clusters and carbon supports, which induced a remarkable enhancement 5.1 times in the activity and 24.3 times stability compared with the commercial Pt/C. In another study, an approach of using microwave-assisted synthesis for producing Pt loaded carbon nanotubes (Pt/CNT) was proposed for GOR electrocatalysts, and the Pt/CNT showed a enhancement 6 times in the current density of GOR as well as the stability compared to Pt/C due to the strong metal-support interaction for preventing the Pt aggregation and increased surface area of the CNT support [146]. In addition to the use of carbon-supported Pt catalysts, the creation of hydroxyl-enriched metal oxide (CeO2•xH2O) adlayers on the Pt/CNT catalysts was illustrated to significantly enhance the GOR activity.…”

Stimulation of ethylene glycol electrooxidation on electrodeposited Ni–PbO2–GN nanocomposite in alkaline medium

“…Another pathway leads to the formation of glycolates and formate which can be further oxidized to poisonous products as follows [20][21][22]: But, generalizing the use of EG fuel cells on a commercial scale requires highly efficient and cheap anode catalysts for EGOR. For many years, EGOR has been extensively investigated on various metal and modified metal electrodes such as Pt, Pd Au, Co, Ag, Fe, and Ni in alkaline media [19,[23][24][25][26][27][28][29][30][31]. The use of Pt and Pt-based catalyst anodes are of great importance due to their high efficiency towards the EGOR and the reaction takes place at lower potential values, but its high cost and its poisoning by CO adsorbed species are challenges [6, 10-12, 24, 25].…”
