“…21,44 As observed in Figure 3C, the broad and weak band related to metallic copper (111) has appeared at 43.9 . 10 Disappearance of metallic oxides peaks demonstrated the reduction of nickel and copper oxides completely emerged during the EDR reaction. The observed peaks at 2θ = 27.1 and 29.12 probably proved the existence of carbon in the catalyst after the stability test.…”

“…EDR and ED reactions are strongly endothermic; thereby, ethanol conversion was increased by augmenting the temperature. 10,11 The ethanol conversion was sharply enhanced with an increase in the reaction temperature up to 800 C irrespective to the C/E variable. This result was in accordance with the various reports.…”

“…26,27 It should be pointed that selection of suitable support not only improves thermal stability and catalytic activity but also proposes a chance to coke control. 10,14,28 It is clear that oxide supports based on rare-earth metals decrease the growth of nickel and copper oxide size particle, thereby, prohibiting the formation of bigger particles, which are the main factor for coke deposition, and hinders reoxidation of metallic nickel and copper in the reforming reactions (21). Rare-earth elements were applied in EDR reactions as a modifier of traditional oxide carriers 13 and as bulk support such as CeO 2, 22 La 2 O 3, 13 and Ce x Zr 1Àx O 2.…”

Summary The mechanistic kinetic model through Langmuir‐Hinshelwood (LH) isotherm was derived for ethanol dry reforming (EDR) processaccompanied by the ethanol decomposition (ED) and methane dry reforming (MDR). For justifying mechanistic relation, EDR tests wereaccomplished under a vast range of operating variables (including temperature varied from 500°C to 900°C and ratio of CO2 to C2H5OH in the inlet feed [C/E ratio] of 1‐3) over a Ni‐Cu/La2O3 catalyst. The physicochemical properties of the fresh and spent catalysts were investigated via inductively coupled plasma atomic emission spectrometer (ICP‐AES), X‐ray diffractometer (XRD), transmission electron microscopy (TEM), thermal gravimetric analysis (TGA), temperature programmed reduction (TPR), and N2 adsorption/desorption tests. The ethanol conversion near to 100% was obtained at 850°C and a C/E ratio of 1, and no obvious deactivation was observed up to 800 min initial on stream. The estimation procedure of kinetic parameters was conducted via nonlinear least square regression to correlate between rate and equilibrium constants in terms of temperature via Arrhenius and van't Hoff equations, respectively. The error of the kinetic model was measured as 11.92% and predicted ethanol conversion with higher precision than other responses. The ethanol conversion and H2 yield higher than 90% achieved beyond 800°C regardless of the C/E ratio. A maximum point was located at 700°C for CO2 conversion trend vs the temperature. An increase in the C/E ratio resulted in ethanol conversion and CO yield, while trends of the CO2 conversion and H2 yield passed from a maximum point. H2 yield 93.45% was obtained at 800°C and a C/E ratio of 1.5 in presence of Ni‐Cu/La2O3 catalyst, which was bigger than reported values by various scientists.

The reduction of molecular oxygen is considered to be a key reaction for electrochemical energy conversion in direct methanol fuel cells (DMFCs). The slow kinetics of oxygen reduction reaction along with the high cost of Pt catalyst hampers the application of fuel cells. In this study, we have reported for the first time oxygen reduction reaction (ORR) activity on rare earth cerium containing perovskite oxides composite with vulcan carbon (VC) in alkaline media. The study has demonstrated the synergistic role of vulcan carbon in cerium perovskite nanomaterials-VC composite for improving ORR activity. The 60 % CeCuO 3 -VC perovskite oxide composite with surface areas of 180 m 2 /g showed better oxygen reduction capability as compared to that of bare cerium perovskite. On optimization, among all the prepared catalysts 60 % CeCuO 3 -VC showed the highest ORR activity with low onset potential and high current density. Further, the optimized 60 % CeCuO 3 -VC followed the 4e À pathway with 95 % methanol tolerance properties and high stability i.e 76 %. This study on ceriumbased perovskite with vulcan carbon will provide an opportunity for the study of rare earth cerium perovskite electrocatalysts for electrochemical energy conversion.
