Bimetallic Ru-Ni/TiO2 catalysts for hydrogenation of N-ethylcarbazole: Role of TiO2 crystal structure

Ultrasound-excited hydrogen radical from NiFe layered double hydroxide for preparation of ultrafine supported Ru nanocatalysts in hydrogen storage of N-ethylcarbazole

“…The calculation formula of mass hydrogen storage was described in our previous work [36] . The initial hydrogenation rate was calculated based on the consumption of H 2 within 10 min of the initial reaction, that is, the number of H 2 moles consumed on Ru catalyst per unit time and per unit mass (mol H2 ∙min −1 ∙g Ru -1 ) [18] , [37] .…”

“…In addition, they also discovered the catalytic activity of the supported Ru catalyst was significantly better than that of the unsupported Ru catalyst. Yu et al [18] found that the catalytic activity in NEC hydrogenation over Ru/TiO 2 -P25 (anatase/rutile = 1/4 mixture) was significantly better than that of Ru/TiO 2 -rutile and Ru/TiO 2 -anatase catalysts, indicating that the different crystal structures of support also affected the catalytic performance. Therefore, choosing a suitable catalyst support and active metal is the key to prepare a high catalytic performance catalyst for NEC hydrogenation.…”

A magnetic field strategy to porous Pt-Ni nanoparticles with predominant (111) facets for enhanced electrocatalytic oxygen reduction

“…The Ni 2p XPS spectra of Pt-Ni/G catalysts at 2.0 T shows that the Ni is in the oxidizing state (Fig. 1e) [28]. As compared to the chemical states of Pt 0.1 Ni/ G catalyst (Fig.…”

Study of catalytic hydrogenation and dehydrogenation of 2,3-dimethylindole for hydrogen storage application

“…Carbazolebased compounds, such as N-ethylcarbazole (NECZ, mp: 70 C) and N-propylcarbazole (NPCZ, mp: 48 C), were investigated most widely as LOHCs by a lot of groups. [40][41][42][43][44][45] Although dehydrogenation of these hydrocarbon molecules was required at temperatures above 250 C, 54 these mixtures were still regarded as attractive LOHCs as the result of their low melting point (À34-36 C), high boiling point (390 C), low ammability and low costs. Recently, indole-based compounds were also suggested as LOHCs, such as indole, 55,56 N-methylindole (NMID), 57 1,2-dimethylindole 58 and 7-ethylindole (7-EID).…”
