In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Untangling the cobalt promotion role for ruthenium in sodium borohydride dehydrogenation with multiwalled carbon nanotube-supported binary ruthenium cobalt catalyst, published in 2021, which mentions a compound: 14898-67-0, Name is Ruthenium(III) chloride xhydrate, Molecular Cl3H2ORu, Quality Control of Ruthenium(III) chloride xhydrate.
In the present study, multiwalled carbon nanotube-supported Ru (Ru/MWCNT) and RuCo (RuCo/MWCNT) nanocatalysts with 3 wt% Ru loading were synthesized via sodium borohydride (SBH) reduction method for the dehydrogenation of SBH (RSBH). These nanocatalysts were characterized with XRD, XPS, SEM-EDX, and TEM. Ru/MWCNT and Ru:Co/MWCNT catalysts with varying Ru:Co at. ratios were prepared successfully, and electronic state of Ru:Co altered compared to Ru. RSBH activities of these Ru/MWCNT and RuCo/MWCNT were examined in alk. environment. RuCo/MWCNT at 80:20 at. ratio exhibits superior H2 evolution. Further experiments were performed with RuCo/MWCNT at 80:20 at. ratio to determine how NaOH concentration (CNaOH), reaction temperature (Trxn), SBH concentration (CSBH), and amount of nanocatalyst (Mc) affect RSBH activities. Activation energy (Ea) was calculated using the Arrhenius equation. RuCo/MWCNT at 80:20 at. ratio exhibits superior H2 evolution activities compared to the literature values. Initial rate (IR) for this nanocatalyst was found as 123.9385 mL H2 g-1cat min-1. As a result of these kinetic calculations, the Ea of the nanocatalysts was calculated as 35.978 kJ/mol. The degree of reaction (n) was found to be 0.53 by trial and error. RuCo/MWCNT at 80:20 at. ratio is a promising nanocatalyst for RSBH.
From this literature《Untangling the cobalt promotion role for ruthenium in sodium borohydride dehydrogenation with multiwalled carbon nanotube-supported binary ruthenium cobalt catalyst》,we know some information about this compound(14898-67-0)Quality Control of Ruthenium(III) chloride xhydrate, but this is not all information, there are many literatures related to this compound(14898-67-0).
