Summary: The [Zn,Mo]/HZ-5 catalysts were prepared using the impregnation method, and the effect of Mo content on catalytic performance was investigated. The catalysts were characterized by various techniques, and it was found that coaromatization process had higher aromatics yield and better stability. The modification with Mo species regulated the acidity of Zn/HZ-5 and increased the amount of Zn(OH)(+) species, resulting in improved dehydroaromatization ability and higher aromatics yield. The carbon deposit and deactivation behaviors were also studied, and under the optimized conditions of 470°C and WHSV = 1.0 h(-1), the BTEX yield reached a maximum of 64.0%.

Summary: The selective aromatization of n-hexane was achieved by using CO2 over a Zn modified HZSM-5 catalyst, which effectively suppressed the hydrogen transfer between olefins and aromatics. This was achieved by the dynamic evolution of the Zn-OH+-(CO)-O-Zn structure, which removed in situ H originated from C-H activation. As a result, the Zn/ZSM-5-CO2 catalyst exhibited a record high BTEX yield of 49.7%, nearly 10% higher than the Zn/ZSM-5-N2 catalyst (40.3%), indicating its potential for profitable utilization of petrochemical resources.

Summary: MWW zeolite is an excellent catalyst for the liquid-phase alkylation of benzene with light olefins. In this study, MCM-49 zeolite was synthesized with cyclohexylamine and shaped into cylindrical catalysts using silica sol and pseudoboehmite. The properties of the parent zeolite and shaped catalysts were characterized, and the catalytic performance of the shaped catalysts was evaluated. The results showed that HMCM-49-SiO2, with fewer Lewis acid sites and excellent diffusion property, exhibited superior catalytic performance and stability compared to the counterpart using Al2O3 as a binder.

Summary: In this study, the phase evolution of Fe-based catalysts in CO2-assisted dehydrogenation was investigated. It was found that Fe3C is the active phase for propane dehydrogenation and shows high activity for reforming and cracking when CO2 is introduced. Higher CO2/i-C4H10 feed ratio leads to a longer persistence of iron species in a higher valence state. Fe3O4 phase remains stable with a CO2/i-C4H10 feed ratio of 1/2 or higher, resulting in a relatively stable isobutane conversion.

Summary: In this study, one-dimensional SAPO-11, SAPO-31, and SAPO-41 with different pore sizes were synthesized and used as supports for Pd catalysts. Molecular dynamics simulation revealed that the diffusion of reactants and intermediates in the micropore channels was strongly affected by the opening size of the channels. The Pd/SAPO-31 catalyst showed the highest activity and yield of iso-hexadecane in the hydroisomerization of n-hexadecane, attributed to improved diffusion and favorable metal-acid balance. Furthermore, it was found that the hydroisomerization over Pd/SAPO-31 occurred via the key lock mechanism, leading to a high proportion of multi-branched iso-hexadecane at high conversion of n-hexadecane. The Pd/SAPO-31 catalyst was proven to be an effective bifunctional catalyst for industrial biodiesel production.

This study developed Zn-BTC MOF and its composites with CaIn2S4, achieving highly efficient and robust photocatalytic CO2 reduction to CH3OH under ambient conditions, using H2O2 as the hydrogen source. Among the composites, ZMCIS4 demonstrated excellent performance with a CH3OH evolution of 49100 μmol/g.cat and a quantum efficiency of approximately 78.41%. The enhanced performance was attributed to the production of nascent hydrogen atoms (H center dot) through the photo-splitting of H2O2 on the ZMCIS surface.

Among them, an amorphous silica-alumina catalyst (SAL-3) modified with Ag showed the highest improvement in catalytic activity and stability when operated in H2 flow. The generation of reversible acid sites was found to be the reason behind the enhanced activity and stability of this Ag/SAL-3 catalyst. The effects of various parameters on the catalytic activity of Ag/SAL-3, such as reaction temperature, contact time, Ag content, and carrier gas, were investigated.
