二機能性電極の相乗効果による電気化学的バイオマス再生と水素製造

将金属前驱体在320℃高温下注入聚胺中，制备了由Pd、Ru、Ni、Co和Cu组成的高熵合金纳米颗粒。XRD图显示为FCC相，而STEM图显示PdCu和RuNiCo在单个纳米颗粒中呈异质分布。这可能是由于金属前驱体的还原速度不同所致。以聚乙烯吡咯烷酮为表面活性剂，在230℃下将金属前驱体热注射到三甲基二醇中，制备了铂族金属的高熵硒化物。XRD谱图表明所制备的硒化物呈非晶结构，STEM谱图证实其没有有序的晶格。元素映射显示Ru、Rh、Pd、Ir、Pt和Se在纳米颗粒中的均匀分布。

High-entropy alloy nanoparticles consisting of Pd, Ru, Ni, Co and Cu have been prepared by hot injection of metal precursors into oleylamine at 320 degrees C. The XRD pattern shows FCC phase while the STEM images show the heterogenous distribution of PdCu and RuNiCo in one single nanoparticle. This might be due to the different reduction speeds of metal precursors.High-entropy selenide of platinum-group metals has been prepared by hot injection of metal precursors into trimethylene glycol at 230 degrees C with polyvinylpyrrolidone as the surfactant. The XRD pattern shows that the selenide prepared exhibits an amorphous structure and the STEM confirms the absence of ordered crystal lattices. The elemental mapping shows the homogeneous distribution of Ru, Rh, Pd, Ir, Pt and Se in the nanoparticles.
