Summary: Blue hydrogen production by steam methane reforming (SMR) with carbon capture is the most commercially viable method, and sorption-enhanced steam methane reforming (SESMR) can further decrease the cost of H2 production. Introducing additional metal elements to improve the performance and prevent catalyst deactivation has been an effective solution. This review summarizes recent developments and highlights the potential of bi/polymetallic catalysts for SMR.

Summary: This study demonstrates a facile aerosol-based method to prepare hybrid nanostructures for catalyzing steam-promoted CO2 reforming with methane. The resulting NiPdOx-CeO2 nanoparticles deposited on SiO2 nanoparticle clusters exhibit superior catalytic performance at low temperatures, with high turnover frequency, tunable H2/CO ratio, and long-term operation stability. Incorporating SiO2 nanoparticle clusters as support material helps to enhance the dispersion of active metals and suppress metal sintering.

Summary: This study focuses on the application of Y-promoted Ni-based catalysts supported on bulk and hollow Al2O3 supports in the steam reforming of methane process. Various characterizing techniques were employed to analyze the catalysts. The 20Ni-3.0Y/HAl catalyst showed the highest methane conversion, hydrogen yield, and H2/CO molar ratio at 700 degrees C, possibly due to the larger surface area of the hollow alumina support compared to the bulk one.

Summary: Catalysts based on Ni/PrO2-ZrO2 mixtures show excellent catalytic performance in various reactions. The PrO2-ZrO2 solid solution as a catalytic support can enhance the production of syngas and reduce carbon deposition. In situ characterization of the catalysts reveals that higher PrO2 content helps optimize the catalyst structure and improve activity and stability.

Summary: Dry reforming of methane (DRM) is a green alternative for utilizing greenhouse gases and producing syngas. The main limitations of DRM are catalyst sintering and coking. Recent studies have focused on Ni-based catalysts for DRM due to economic constraints on noble metal-based catalysts. Mesoporous silica (MS) supported catalysts show promise due to their high surface areas, thermal stability, and easy availability. However, research on MS as a catalyst support for DRM is still limited.

Summary: The modification of Ni-based catalysts by CeO2 and ZrO2 suppresses the negative effect of O-2, leading to high CH4 and CO2 conversion rates even at high temperatures. The interaction among Ni, CeO2, and ZrO2 results in well-dispersed Ni particles, contributing to long-term catalyst stability and high conversion rates.

Summary: This study achieved plasma-catalytic dry reforming of biogas using Ni-based bimetallic catalysts, which resulted in high conversion, yield and selectivity of key gas products, and high fuel production efficiency (FPE). The coupling of DBD with 10Ni3Co showed the best reaction performance, and also helped suppress carbon deposition and reduce energy costs. The use of Ni-based catalysts allowed for tuning of product distribution, favoring the generation of C3-C4 hydrocarbons and syngas. The 10Ni3Co catalyst exhibited superior performance due to factors such as higher specific surface area, improved CO2 adsorption capability, strong metal-support interactions, enhanced reducibility, and Ni-Co alloy formation.

Summary: The study investigated the steam-CO2 reforming of biomass derived synthesis gas using Rh-loaded alumina foam monolith catalysts, showing that the steam concentration in the feed plays a crucial role in determining the reaction products and pathways. Higher steam concentration favored steam methane reforming and water gas shift reaction, while increasing temperature enhanced methane dry reforming and reverse-water gas shift reaction.

Summary: In this study, ZSM-5 zeolite was prepared without organic templates using a hydrothermal process, and the synthesis kinetics were investigated based on crystal growth. The results showed that increasing the Na+ content in the initial gel composition decreased the activation energy for crystal growth and enhanced the crystallization rate of ZSM-5 zeolite.

Summary: This study investigated the effect of synthesis conditions on the crystal growth, structural features, acidity, and catalytic properties of hierarchical ZSM-5 zeolite in n-heptane cracking. The results showed that the crystallization rate of hierarchical ZSM-5 increased with the amount of SiO2 and Na2O in the initial gel, as well as the reaction temperature. Additionally, by adjusting the initial gel composition and reaction temperature, the porosity, acidity, and crystal size of hierarchical ZSM-5 could be controlled. The selectivity of ethylene and propylene in the heptane cracking reaction was found to be influenced by the acidity and micropore to mesopore ratio of the prepared zeolites, as predicted by both experimental and simulation results.
