The traditional wisdom of utilizing water in practical olefin synthesis has been viewed as a means to reduce alkane partial pressure and assist in coke removal. However, under such harsh reaction conditions, the potential catalytic role of the water molecule remains unclear. This study explores the intriguing concept that the water molecule, through the selective excitation of molecular vibrations and collisions induced by thermal energy and thermal radiation, could act as a catalyst in homogeneous gaseous propane dehydrogenation. This occurs via the generation of the OH⋅ radicals, resulting in an olefin yield of 37.93 %, a single pass propane conversion of 51.14 %, and an excellent stability of more than 2000 hours.

Research results about the structure, acid-base, redox, and adsorption characteristics of zinc(yttrium)-containing dealuminated BEA zeolites (Si/Al=1000), Zn(Y)SiBEA and their catalytic properties in the propane dehydrogenation with CO (CO-PDH) are presented. The catalysts were prepared through a two-step procedure involving complete dealumination of the BEA zeolite followed by the introduction of Zn and Y cations into vacant T-atom sites, by impregnation. The samples obtained were characterized using XRD, XPS, Si DP MAS NMR, low-temperature N ad/desorption, TPR-H, CH/CH (CO, NH)-TPD, and FTIR-Py techniques.

Vanadium-based catalysts have been regarded as a promising candidate for Pt- and Cr-based materials in propane dehydrogenation (PDH) application. However, regulating the coordination environment and polymeric degree of vanadium oxides (VO) at nanoscale level remains great challenges. Herein, an efficient VO catalyst with the adjustable polymeric degree is achieved by a surface hydroxyl-modulation.

Gallia-alumina (GaAlO), promoted with a trace amount of Pt, exhibits excellent activity and selectivity in propane dehydrogenation (PDH) due to a bifunctional mechanism. Tetrahedrally coordinated Ga (Ga) catalyzes C-H dissociation, while Pt facilitates H recombination into H. To maximize the utilization of precious Pt and Ga, it is crucial to understand the optimal balance between the two catalytic functions or determine the 'ideal regime.
