Fabrication of Pt–CeO2 nanoparticles supported sulfonated reduced graphene oxide as an efficient electrocatalyst for ethanol oxidation

Chlorine-doped reduced graphene oxide nanosheets as an efficient and stable electrode for supercapacitor in acidic medium

“…RGO was synthesized from graphite rod according to previous works but we shall briefly repeat the main features here [24][25][26][27]. Static potentials of 5 V using a DC power supply were applied to the 2 graphite electrodes and exfoliation of graphite was occurred.…”

Electrocatalytic Oxidation of Ethanol on the Surface of Graphene Based Nanocomposites: An Introduction and Review to it in Recent Studies

“…prepared a Pt/CeO 2 /sulfonated reduced graphene oxide (SRGO) nanocomposite through anchoring CeO 2 and Pt nanoparticles on the oxygenated functional groups existing on the surface of SRGO sheets (Figure ), exhibiting not only a better catalytic activity but also a lower activation energy for ethanol electro‐oxidation reaction in comparison with Pt/RGO with Nafion and Pt/SRGO. It was demonstrated by XRD analysis that the prepared catalyst consists of segregated nanocrystalline deposits and no alloy phase formation between CeO 2 and Pt, as depicted in Figure …”

“…It is believed that the conventional strategies employed for the energy generation and conversion are no longer appropriate to make progress in the world. Hence, the severe problems faced by human society, including the environmental pollution and energy crisis, arising from not only the ever increasing energy demand but also the great combustion of fossil fuels, coupled with the decrease in the supply of fossil fuels have resulted in a huge attention to the improvement of fuel cells over the past several decades . Fuel cells are extensively regarded as sustainable energy conversion devices.…”

Effect of Confined Spaces in the Catalytic Activity of 1D and 2D Heterogeneous Carbon‐Based Catalysts for Synthesis of 1,3,5‐Triarylbenzenes: RGO‐SO3H vs. MWCNTs‐SO3H

“…Recently, Kakaei and co‐workers reported several papers regarding the synthesis and exfoliation of GO from graphite in the ionic liquids and different surfactants for different applications . For example, the mentioned group prepared different functionalized GO including PtCeO 2 /SRGO, NiCo/NRGO, Pt 3 Sn/GO, and Pt/graphene for ethanol and methanol oxidation processes. Also, they synthesized different nanocomposites of GO for oxygen reduction process and supercapacitors ,, …”
