“…The proposed modifications of the catalysts are most broadly related to the improvement of the dispersion of copper particles and the enhancement of their redox properties [68]. Among promoters for copper catalysts, ZrO 2 [68,69], Ga 2 O 3 [73], TiO 2 [66], ZnO [71], CeO 2 [57,68,74], MgO [71,75], yttrium [72], lithium, sodium potassium [75], and lanthanum [76] have been reported. The amount of promoter added to the catalyst structure strongly affects the catalytic activity; therefore, the selection of the appropriate promoter content is crucial for the activity and selectivity of the methanol steam reforming process.…”

“…Moreover, the addition of titanium promotes the reduction of the acidity of the catalyst, thus limiting the occurrence of side reactions. It was also reported that a basic promoter, including Na, K, Mg, may be used as a sorbent for generated carbon dioxide, allowing for obtaining a gas stream with an even higher hydrogen content [75].…”

Recent Progress on Hydrogen Storage and Production Using Chemical Hydrogen Carriers

Depleting fossil fuel resources and anthropogenic climate changes are the reasons for the intensive development of new, sustainable technologies based on renewable energy sources. One of the most promising strategies is the utilization of hydrogen as an energy vector. However, the limiting issue for large-scale commercialization of hydrogen technologies is a safe, efficient, and economical method of gas storage. In industrial practice, hydrogen compression and liquefaction are currently applied; however, due to the required high pressure (30–70 MPa) and low temperature (−253 °C), both these methods are intensively energy consuming. Chemical hydrogen storage is a promising alternative as it offers safe storage of hydrogen-rich compounds under ambient conditions. Although many compounds serving as hydrogen carriers are considered, some of them do not have realistic perspectives for large-scale commercialization. In this review, the three most technologically advanced hydrogen carriers—dimethyl ether, methanol, and dibenzyltoluene—are discussed and compared. Their potential for industrial application in relation to the energy storage, transport, and mobility sectors is analyzed, taking into account technological and environmental aspects.

“…18 Therefore, the development of a feasible pathway to simultaneously improve the hydrogen concentration and lower the CO selectivity, through which the thermodynamic equilibria of both SRM and WGS can be promoted by in situ CO 2 adsorption. 21,22 A few experimental studies have been conducted to verify the feasibility of SE-SRM by using intermediate-temperature CO 2 sorbents such as MgO and hydrotalcite. Wu et al 23 investigated the hydrogen production characteristics of SE-SRM at 230 C under atmospheric pressure, using commercial CuO/ZnO/Al 2 O 3 and K 2 CO 3 -modied hydrotalcite as a catalyst and CO 2 sorbent, respectively.…”

In Situ DRIFTS-MS Methanol Adsorption Study onto Supported NiSn Nanoparticles: Mechanistic Implications in Methanol Steam Reforming

Methanol adsorption over both supported NiSn Nps and analogous NiSn catalyst prepared by impregnation was studied by in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) to gain insights into the basis of hydrogen production from methanol steam reforming. Different intermediate species such as methoxides with different geometry (bridge and monodentate) and formate species were identified after methanol adsorption and thermal desorption. It is proposed that these species are the most involved in the methanol steam reforming reaction and the major presence of metal-support interface sites in supported NiSn Nps leads to higher production of hydrogen. On the basis of these results, a plausible reaction mechanism was elucidated through the correlation between the thermal stability of these species and the evolution of the effluent gas released. In addition, it was demonstrated that DME is a secondary product generated by condensation of methoxides over the acid sites of alumina support in an acid-catalyzed reaction.
