Summary: In this study, attapulgite-based MCM-41 (AM) was synthesized using attapulgite as a silicon source, and AM-supported Ni/Ce/Zr catalysts were manufactured by sol-gel assisted impregnation method. It was found that the optimal Ce-Zr additives and calcination temperature could enhance the electronic interaction among Ni/Ce/Zr components, resulting in the highest ethanol conversion rate and stability of the catalyst. This study provides a new opportunity for the preparation of efficient and low-cost AM-supported Ni/Ce/Zr catalysts for ethanol steam reforming.

Summary: The idea of hydrogen production through dry reforming of methane (DRM) is excellent for decreasing greenhouse gas concentration. The addition of ceria to the yttria-zirconia supported nickel catalyst enhances its catalytic activity. The addition of 2 wt% ceria reduces the crystallinity of metallic nickel, increases the CH4 decomposition sites and oxygen mobility, resulting in a 79% H2 yield.

Summary: A carbon-based catalyst was prepared by Ni/Co modification of acid pickling biochar from peanut shell. The modified catalyst showed abundant pore structure and oxygen-containing functional groups, providing more active sites for metal particles loading. It exhibited high catalytic activity for steam reforming of acetic acid and could be a potential catalyst for the production of H-2.

Summary: In this study, an acid-modified vermiculite (AVM)-supported Pd-Ni bimetallic catalyst was investigated for the hydrodeoxygenation of bio-oil and its model compounds. The catalyst efficiently hydrodeoxygenated phenol, reaching 94% conversion at 0.5% Ni loading and temperatures beyond 513 K. The synergistic effects between the active component and the carrier were found to be the main reason for the catalytic activity, with significant influences of Ni loading and temperature on the hydrogenation of phenol.

Summary: The use of a catalyst support for the design of nanoscale heterogeneous catalysts based on cerium oxide offers vast possibilities for future catalyst development. In this study, zirconia-supported ceria catalysts were synthesized and characterized. Experimental results show that the formation of reversible reactive pyrochlore structures can be achieved through low-temperature reduction-oxidation pretreatment, without altering the morphology of the catalyst.

Summary: In this study, the strong metal-support interaction (SMSI) phenomenon for supported Ni/CeO2 catalysts with different CeO2 nanomorphologies was systematically explored. The degree of encapsulation of Ni particles originating from the SMSI effect was found to be positively correlated with the CO2 hydrogenation activity. Quasi in situ XPS and in situ DRIFTS techniques were used to reveal the relevant species and reaction pathways. These findings provide a fundamental strategy for tailoring catalytic performance by adjusting the support surface structure.

Summary: The study found that bimetallic catalysts can significantly decrease the Ni reduction temperature and increase the H-2 yield during steam reforming reaction of acetic acid, with 15Ni/ZrO2 performing the best. However, contrary to expectations, the performance of bimetallic catalysts was not as good as that of monometallic Ni catalysts.

Summary: This study investigates the conversion of biomass bio-oil to hydrogen using a blend of acetic acid and acetone as a model compound. The 3D-LaNiO3 catalyst synthesized by a silica template method is found to have smaller crystal size and higher oxygen vacancies, enhancing its redox ability and resistance to coke deposition. The catalyst shows great activity in producing hydrogen-rich syngas, with the highest H2 gas yield observed at 600 degrees C and a steam/carbon mole ratio of 3. The stability of the perovskite structure and its ability to resist coke deposition contribute to the sustained catalytic activity.

Summary: The development of efficient oxide-supported bimetallic catalysts is crucial for ammonia synthesis or other hydrogen-involved reactions. In this study, ceria-supported Co-Mo bimetallic catalysts with different properties were designed by changing the addition of Mo, resulting in enhanced ammonia synthesis activities. It was found that the negative effect of molybdenum oxide on the reduction of the bimetallic catalyst could be effectively alleviated by the subsequent addition of Mo species, leading to improved catalyst activity.
