“…A very well-known effect of deactivation quenching is by increasing the basicity of the support and/or decrease its acidity [56]. Kumar et al [264] have indicated some of the trends within the use of basic support in the reforming of acetic acid: CeO2, and ZrO2 have interesting redox features together with basic character. The incorporation of La2O3 [265] or Ca and Mg [266] also exhibits enhanced coke resistance.…”

“…Cobalt‐based catalysts have been reported for their high activity and selectivity in ATR of HOAc 4, 8; however, deactivation caused by cobalt metal oxidation, sintering, and coking 9 remains the main concern for sustainable hydrogen production 10. Accordingly, strategies for modification of crystal phases and strong metal‐support interaction (SMSI) have been adopted 11, and specific structures, e.g., hydrotalcite‐like structure, dolomite, olivine, solid solution, and ordered mesoporous structure, were synthesized and showed improved reactivity 12.…”

Autothermal reforming (ATR) of acetic acid (HOAc) is a promising and alternative route for hydrogen production from renewable resources, but catalyst deactivation caused by cobalt metal sintering and coking is a major concern in ATR. In this work, perovskite‐like catalysts of the formula SrxTi1–xCoO3±δ (x = 0, 0.2, 0.5, and 0.8) were prepared by evaporation‐induced self‐assembly and then evaluated in ATR for hydrogen production. The SrxTi1–xCoO3±δ catalysts exhibited high activity and stability as well as 100 % conversion of HOAc. Additionally, the Co particles with strong metal‐support interaction of SrTi(Co)O3 inhibited coking and agglomeration, and showed potential for hydrogen production by the ATR process.

By introducing Mg, Cu, Zn, Sn, and Mn into the synthesis processes of Ni and Al based hydrotalcite, Ni–Al layered hydrotalcite-derived catalysts with different metal compositions were prepared. In this paper, the effect of metal composition on the structure of Ni–Al layered hydrotalcite-derived catalysts is investigated, and then catalytic activities of prepared catalysts with different metal compositions on ethylene glycol aqueous-phase reforming are analyzed. The physicochemical properties of the Ni–Al layered hydrotalcite-derived catalysts were characterized by X-ray diffraction (XRD), temperature-programmed reduction (TPR), and nitrogen adsorption–desorption technology. The obtained hydrotalcite-derived catalysts were applied to the process of ethylene glycol aqueous-phase reforming (APR). The XRD results confirmed that the precursors of hydrotalcite-derived catalysts with metal compositions of Ni/Mg/Al, Ni/Cu/Al, Ni/Zn/Al, and Ni/Sn/Al had hydrotalcite crystalloid morphology. During the process of ethylene glycol aqueous phase reforming, all the catalysts showed high conversion of ethylene glycol (>90%), and the optimum hydrogen yield (73.5%) was obtained when using the catalyst with metal composition of Ni/Mg/Al at 225 °C under 2.6 MPa in nitrogen atmosphere for 2.5 h.
