“…The result of the research is consistent with the structure of pristine ATC in the literature [49,50]. In Figure 3A,B, it can be seen that the analogy in respect of morphology between PM-Ni/ATC and IM-Ni/ATC were also observed, which may be ascribed to their similar preparation procedure [41]. As shown in Figure 3C, the Ni particle size on the surface of MM-Ni/ATC is larger and the aggregation of them is severer than those of the other two catalysts.…”

“…Because of the weak bonding force in MM-Ni/ATC, these free Ni particles are easily reduced deeply before reaction, which results in the higher activation at the initial stage of the reaction. Meanwhile, these free Ni particles could also overcome the crystal force of surface and agglomerate to emerge larger size crystallites during the reforming process, which accelerates the deactivation of the catalysts [41]. These results are demonstrated by catalytic test of all catalysts, as shown in Section 2.2.…”

“…From Table 1, it also displays that the surface areas of the three catalysts, which are similar to one another, are significantly increased compared with that of ATC, and the pore volumes of them are very close to that of ATC. In short, the three synthesis methods can enlarge the surface areas of the catalysts, and further enhance the catalytic activity and metallic dispersion of them [41,48]. Both nature ATC and the three Ni/ATC catalysts exhibit well-defined hysteresis loops of H 3 Type (Figure 2a), demonstrating that the samples are made up of plate-like particles (loose assemblages) forming slit-like pores [47].…”

“…Furthermore, the diffraction peaks at 2θ of 44.5 • and 51.8 • are attributed to crystal phase of Ni • species (JCPDS PDF# 04-0850) in all reduced and spent catalysts. This is because NiO species are highly disperse on the surface of ATC and strongly interactive with ATC through the synthesis methods of precipitation and impregnation, resulting in the crystal phase of NiO which cannot be detected by XRD in fresh PM-Ni/ATC and IM-Ni/ATC catalysts [25,41]. By comparison, among the XRD spectra of reduced and spent catalysts of these three Ni/ATC catalysts, the intensities of the Ni • peaks are increased in the order of MM-Ni/ATC > PM-Ni/ATC > IM-Ni/ATC.…”

“…This result manifests that the bonding crystal force inside the structures of PM-Ni/ATC and IM-Ni/ATC is stronger than that of MM-Ni/ATC. It is well known that Ni • particles in Ni-based catalysts contribute to the catalytic activation of SR reaction [17,41]. Because of the weak bonding force in MM-Ni/ATC, these free Ni particles are easily reduced deeply before reaction, which results in the higher activation at the initial stage of the reaction.…”

Abstract:In this research, catalytic steam reforming of acetic acid derived from the aqueous portion of bio-oil for hydrogen production was investigated using different Ni/ATC (Attapulgite Clay) catalysts prepared by precipitation, impregnation and mechanical blending methods. The fresh and reduced catalysts were characterized by XRD, N 2 adsorption-desorption, TEM and temperature program reduction (H 2 -TPR). The comprehensive results demonstrated that the interaction between active metallic Ni and ATC carrier was significantly improved in Ni/ATC catalyst prepared by precipitation method, from which the mean of Ni particle size was the smallest (~13 nm), resulting in the highest metal dispersion (7.5%). The catalytic performance of the catalysts was evaluated by the process of steam reforming of acetic acid in a fixed-bed reactor under atmospheric pressure at two different temperatures: 550 • C and 650 • C. The test results showed the Ni/ATC prepared by way of precipitation method (PM-Ni/ATC) achieved the highest H 2 yield of~82% and a little lower acetic acid conversion efficiency of~85% than that of Ni/ATC prepared by way of impregnation method (IM-Ni/ATC) (~95%). In addition, the deactivation catalysts after reaction for 4 h were analyzed by XRD, TGA-DTG and TEM, which demonstrated the catalyst deactivation was not caused by the amount of carbon deposition, but owed to the significant agglomeration and sintering of Ni particles in the carrier.

With increasing global emphasis on environmental sustainability, the reliance on traditional energy sources such as coal, natural gas, and oil is encountering significant challenges. H2, known for its high energy content and pollution‐free usage, emerges as a promising alternative. However, despite the great potential of H2, approximately 95% of hydrogen production still depends on non‐renewable resources. Hence, the shift towards producing H2 from renewable sources, particularly through methods like steam reforming of methanol ‐ a renewable resource ‐ represents a beacon of hope for advancing sustainable energy practices. This review comprehensively examines recent advancements in efficient H2 production using Ni‐based catalysts in methanol steam reforming (MSR) and proposes the future prospects. Firstly, the fundamental principles of MSR technology and the significance in clean energy generation are elucidated. Subsequently, the design, synthesis techniques, and optimization strategies for enhancing the catalytic performance of Ni‐based catalysts are discussed. Through the analysis of various catalyst compositions, structural adjustments, surface active sites, and modification methods, the review uncovers effective approaches for boosting the activity and durability of MSR reactions. By offering a comprehensive critical analysis, this review serves as a valuable reference to enhance MSR hydrogen production efficiency and catalyst performance.
