A heterogeneous ruthenium catalyst consisting of isolated single atoms and disordered clusters stabilized in a N-doped carbon matrix has been synthesized with very good activity remarkable regioselectivity the hydroformylation 1-hexene. The role nitrogen heteroatoms probed essential to increase stability activity, enabling stabilization Ru(II)–N sites according X-ray photoelectron spectroscopy (XPS) XANES. Intrinsic size-dependent Ru species different atomicity extracted, correlating...
Bifunctional atomically dispersed ruthenium electrocatalysts with a low metal loading (0.2 wt%) exhibit outstanding performance for bipolar membrane water electrolysis.
Abstract Dodecacarbonyltriruthenium Ru 3 (CO) 12 has been immobilized onto a biopolymer (chitosan) supported on SiO 2 (Ch@SiO ) to give Ru−Ch@SiO . Ch@SiO behaves as soft, recoverable and bulky ligand allowing the stabilization of released active species preventing its irreversible reduction 0 Under these conditions very high activity (TOF= 1086 h −1 ; TON=2749) regioselectivity (n:iso=92 : 8) are obtained, surpassing that homogeneous counterpart. Spectroscopic studies have shown transforms...
Atomically dispersed catalysts (ADCs) have recently drawn considerable interest for use in water electrolysis to produce hydrogen, because they allow maximal utilization of metal species, particularly the expensive and scarce platinum group metals. Herein, we report electrocatalytic performance atomically ruthenium (Ru ADCs) with ultralow Ru loading (0.2wt%), which is prepared by impregnating RuCl 3 precursors onto ammonium salt modified carbon support, followed high-temperature pyrolysis....
Electrocatalysts play a crucial role in hydrogen production via water electrolysis. In this presentation, we report the synthesis of atomically dispersed ruthenium (Ru) supported on nitrogen-doped carbon (Ru-NC) with ultra-low Ru loading (0.2 wt%) through two-step deposition-pyrolysis method. Briefly, controlled amounts ammonium alginate (AG), 20% wt., were carbonaceous support (Norit CN-1) followed by subsequent introduction precursor (RuCl 3 ·3H 2 O) under alcoholic solution (1-butanol)....
