Herein, a series of nitrogen-doped hollow carbon hemispheres (HCHs) were prepared using silica as template, asphalt and urea as carbon and nitrogen source. The obtained different nitrogen content HCHs were then applied for supports of PtSn nanoparticles catalyst for ethanol oxidation in acid media. The PtSn nanoparticles were evenly deposited on HCHs with a narrow size distribution. Tunable size and distribution of the PtSn catalysts were obtained by adjusting nirtrogen content. Among all the synthesized PtSn catalysts, nitrogen content was the highest when the mass ratio of asphalt to urea was 2:1. The electrochemical analysis illustrated that the catalyst with highest nirtrogen content presented best electrocatalytic activity and stability for ethanol oxidation in acid media, providing that the HCHs with unique hollow structure and optimum nitrogen doping content can effectively improve the ethanol electrocatalytic activity and stability.

“…[20][21][22] Among these Pt alloys, Pt alloyed with Sn received considerable attention for alcohol oxidation mainly due to their superior performance with high CO-poisoning tolerance. [23][24][25][26] For example, compared with pure nanowires, ultrathin Pt x Sn 1−x Nanowires were found to not only achieve superior activity and stability towards MOR and EOR, but also exhibit a much lower onset that potentials. [27][28][29] Furthermore, the Pt 3 Sn NPs is reported to has higher EOR activity than of PtSn NPs.…”

Multimetallic nanoparticles (NPs) often exhibit enhanced catalytic properties that differ from their parent materials. Carefully exploring the structures of multimetallic NPs is a prerequisite for understanding the structure-and composition-associated properties. Herein, intermetallic Pt/Sn NPs with tunable compositions are designed exploiting the beneficial properties of ionic liquids (ILs) in a one-pot synthetic procedure. Metal salt precursors are reduced with triethylhydridoborate, whereby the cation of the triethylhydridoborate is adapted to the cation of the IL. Both the initial metal precursor ratio and the type of IL influence the structure of the NPs, with the effect of the IL being more pronounced. PtSn nanocrystals are obtained as phase pure products under optimized reaction conditions, whereby a microwave-assisted approach leads to higher crystallinity. In the hydrogenation of α,β-unsaturated aldehydes, the catalytic performance obviously depend on the NP composition. In bimetallic Pt/Sn NPs, higher Pt content leads to increased conversion, while increase in Sn increases selectivity to the cinnamic alcohol.
