Summary: The study deposited highly dispersed nickel nanoparticles on aluminum oxide using atomic layer deposition, and found that the addition of MgO increased the basicity of catalyst surfaces, assisting CO2 adsorption and activation. Although the formation of NiO-MgO solid solution did not improve overall reducibility, the interaction between reduced Ni nanoparticles and MgO inhibited sintering and provided sufficient metal-support interface for CO2 activation, leading to higher methane reforming rates.

Summary: This study investigates the use of Ni/Al2O3 catalysts for dry reforming of methane, with a focus on the effects of different promoters on catalyst stability. Higher iron loading on the catalyst leads to lower coke formation during dry reforming. Additionally, promoters with high CO2 affinity can accelerate catalyst oxidation during regeneration, ultimately leading to sintering and increased coke formation. Promoters with significant CO2 interaction are more effective on sintered catalyst samples compared to unpromoted Ni/Al2O3.

Summary: The effects of vanadium promotion on gamma-alumina supported nickel catalysts for methane dry reforming were investigated. The introduction of vanadium was crucial to hinder catalyst deactivation by coke deposition. The formation of nanotubes was reduced and hydrogen yield increased. When coupled with calcium, selectivity toward hydrogen/syngas production was improved. Under concentrated gases, vanadium was fundamental for a higher activity, with an increase of 30% and 15% in CH4 and CO2 conversions compared with the non-doped catalyst.

Summary: The catalytic behavior of different Ni/Al2O3 catalysts originating from NiO and different Ni/Al2O4 sources for the dry reforming of methane was studied. The catalyst prepared from the stoichiometric Ni/Al2O4 precursor showed higher activity and stability with less carbon deposits, while the catalyst formed from NiO exhibited lower initial activity and notable deactivation due to the encapsulation and separation of Ni metal particles facilitated by weaker metal-support interactions.

Summary: Increasing the calcination temperature of nickel-based catalysts on alumina leads to the formation of nickel-alumina spinel, enhancing metal-support interaction and reducing temperature. It also decreases nickel nanoparticle size and increases effective dispersion due to the formation of nickel aluminate. The catalyst calcined at 750 degrees C shows the highest conversion rates in methane dry reforming and excellent stability in a 200 h test.

Summary: Nickel-based catalysts used in the dry reforming of methane (DRM) face issues of coking and sintering, which limit their industrial application. The addition of an anti-coking additive (CaO) to a commercial nickel catalyst was investigated using thermogravimetric analysis. It was observed that the catalyst sintered at temperatures between 850 and 900 degrees C, leading to permanent deactivation. The coking and carbon gasification rates were found to be equal at temperatures of 796-860 degrees C for the tested Ni/CaO-Al2O3 catalyst, depending on the heating rate.

The synergistic interaction between Ni and Co is found to enhance the activity and total yield of methane and liquid fuels. The optimum operating range for high efficiency co-production of SNG and liquid fuels is determined to be at 550-578 K, H2/CO = 3, 3.0 MPa, and W/F = 5 gcat h mol-1, with the 2Ni-1Co/SiO2 bimetallic catalyst showing promising results.

Summary: In this study, bifunctional catalysts composed of SAPO-34 zeolite and Mn-doped ZnCrAlOy oxide were used for the direct conversion of syngas to light olefins. It was found that Mn doping could decrease the particle size of ZnCrAlOy spinel and increase the formation of oxygen vacancies, which protected more light olefins and intermediates from hydrogenation.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
