A study on the effect of support's reducibility on the reverse water-gas shift reaction over Pt catalysts

Effect of Ce/Ti ratio on the catalytic activity and stability of Ni/CeO2–TiO2 catalyst for dry reforming of methane

“…Interestingly, it was observed that the reaction rate was increased by increased CeO 2 loading. Goguet et al [31] and Kim et al [41][42][43] claimed that carbonate formed at the oxygen vacant sites on the support was the main intermediate of the reaction and noted the importance of the redox characteristics of the support. This is consistent with the TPR results of Fig.…”

Use of CuNi/YSZ and CuNi/SDC Catalysts for the Reverse Water Gas Shift Reaction

“…Good results were also obtained when they were tested individually on catalyst supports [4][5][6] using the RWGS reaction. Metallic pure Cu catalysts have shown a tendency to deactivate over time when exposed to high temperatures [8][9][10].…”

“…In this case the reaction would occur on an extended region of the support surface surrounding the three-phase boundary. Kim et al [5] proposed a similar Langmuir-Hinshelwood mechanism to explain results obtained with a solid oxide fuel cell.…”

“…Also, Pt is stable at high temperatures and produces both high CO selectivity and CO 2 conversion [4][5][6]. However, noble metals such as Pt have a high cost.…”

Influence of attrition milling on V/Ti catalysts for the selective oxidation of ammonia

“…Panagiotopoulou et al [12] reported that the activity of Pt/TiO 2 catalysts with various properties, applied to the water gas shift (WGS) reaction, was affected by the primary crystallite size of TiO 2 . Kim et al [13,14] demonstrated that the primary crystallite size of the catalyst, determined via XRD analysis, was a major factor influencing the catalyst activity. With a smaller primary crystallite size, the turnover frequencies (TOFs)…”
