Stabilizing the isolated Pt sites on PtGa/Al2O3 catalyst via silica coating layers for propane dehydrogenation at low temperature

Peng Wang et al.

Summary: This study presents a strategy to reduce Pt loading and improve propane non-oxidative dehydrogenation activity using silica coating, resulting in a stable catalyst with high activity at low temperature. The prepared 2.5%Si@PtGa/Al2O3 catalyst exhibits outstanding catalytic activity near equilibrium conversion and better stability at 450 degrees C, showcasing a new method to utilize metal-support interaction in catalysis.

Infrared spectra of surface nitrates: Revision of the current opinions based on the case study of ceria

M. Y. Mihaylov et al.

Summary: The structures of nitrates formed on ceria surface were investigated using FTIR spectroscopy and DFT methods, with isotope labelling utilized to strengthen the conclusions. It was found that monodentate nitrates were actually tridentate nitrates with C-2v symmetry, and bidentate nitrates typically bridge and chelate cerium cations. The spectral differences between these species are due to binding geometry and symmetry reduction.

Effect of coking and propylene adsorption on enhanced stability for Co2+ -catalyzed propane dehydrogenation

Yihu Dai et al.

Summary: The addition of Si modifier in propane dehydrogenation reactions over Co2+-Al2O3 catalysts enhances catalytic stability by introducing moderate-strength acid sites, leading to lower graphitization degree and higher reactivity of coke species. The interaction of C3H6 with Co catalysts can be affected by Si modification, influencing the coking property and catalytic stability.

Propane Dehydrogenation on Single-Site [PtZn4] Intermetallic Catalysts

Sai Chen et al.

Summary: The single-site [PtZn4] catalyst developed in this study exhibits high selectivity and ultra-stability, achieving over 95% propylene selectivity in a high temperature range, with no obvious deactivation observed during long-term testing. The surface [PtZn4] ensembles in PtZn IMAs serve as key active site structures, promoting the C-H cleavage of propane while inhibiting further dehydrogenation of surface-bounded propylene, thereby improving selectivity and stability.

Olefin oligomerization by main group Ga3+ and Zn2+ single site catalysts on SiO2

Nicole J. LiBretto et al.

Summary: In this study, it was found that silica-supported, single-site catalysts containing immobilized main group Zn2+ and Ga3+ ion sites can catalyze the oligomerization of ethylene and propylene to produce linear olefins, with rates similar to Ni2+ and higher molecular weight olefins for Ga3+. The oligomerization was suggested to occur via metal hydride and metal alkyl intermediates formed during olefin insertion and beta-hydride elimination elementary steps, with initiation proposed to occur through heterolytic C-H dissociation of ethylene at around 250 degrees C. This study illuminates new chemistry for main group metal catalysts with potential for developing new oligomerization processes.

Zhoufeng Bian et al.

Summary: A novel method is proposed to prepare a stable cobalt oxide catalyst on mesoporous silica matrix for high propylene selectivity in propane dehydrogenation. By adjusting the cobalt content in the silica, the activity and stability of the catalyst are optimized. Physicochemical properties of the catalyst, including high surface area and well-dispersed cobalt oxide, were characterized using various techniques.
