Regulation of the shell thickness and shell components in PtCu/PdCu core–shell tripods for ethylene glycol and glycerol oxidation reactions

Abstract

Bi−component core−shell catalysts constructed from both noble and transition metals have been widely used in alcohol oxidation reactions, especially the introduction of transition metal components that can improve the anti−poisoning...

Ultrathin IrRu nanocages with tunable electronic reciprocity for highly efficient water splitting in acidic media

“…It was previously suggested that Ir was easy to transform into IrO 2 under electro-oxidation, which was a more active and stable species for electro-catalysis. 50 However, the oxidation of Ru was accompanied by over-oxidation to form hypervalent RuO 4 with feeble activity and strong dissolvability. 51 This could explain why the Ir x Ru 1− x nanocages with x ≥ 0.5 exhibited much better stability: more than half of Ir content in Ir x Ru 1− x nanocages produced a large proportion of Ir 4+ , thus reducing the percentage of as-formed RuO 4 and guaranteed the stability for both the HER and the OER.…”

Advancements in catalysts for glycerol oxidation via photo-/electrocatalysis: a comprehensive review of recent developments

“…Interestingly, this strategy can potentially be used to synthesize multi-component core-shell structures like PtCu/ MCu (M: Rh, Ru, Au, Ir). 105 Non-noble transition metal based electrocatalysts. Transition metal-based compounds have been used in various processes ranging from N 2 reduction, CO 2 reduction, and H 2 production through photo-/electrocatalytic, thermocatalysis, and other industrial processes.…”

Dual-phase B-doped FeCoNiCuPd high-entropy alloys for nitrogen electroreduction to ammonia

“…S4f, ESI †). 19 Interestingly, compared to the XPS spectra of DP-HEA/CNFs (Figs. S4b-f, ESI †), the 2p 3/2 peaks from Fe, Co, Ni, Cu and the 3d 5/2 peak from Pd s in DP-B-HEA/CNFs shifted to the higher BEs (0.3 eV).…”
