Ternary noble metal-metalloid-nonmetal PdBS alloy mesoporous nanospheres (MSs) with three-dimensional central-radial pore channels were prepared for an electrocatalytic hydrogen evolution reaction. The synthesis was performed via precise control in the reduction and nucleation growth of ternary PdBS alloy MSs along confined cylinder mesophases assembled by amphiphilic dioctadecyldimethylammonium chloride. The resultant PdBS alloy MSs disclosed a remarkably improved electrocatalytic performance due to their structural and compositional synergies. This finding extended our knowledge on the rational design and targeted synthesis of novel noble metal-metalloid-nonmetal alloys with desired structures and morphologies for catalysis and other applications.
具有三维中心-放射状孔道的三元贵金属-类金属-非金属 PdBS 合金介孔纳米球 (MSs) 被制备用于电催化析氢反应。该合成是通过在由两亲性二辛基二甲基氯化铵组装的受限圆柱介孔相中精确控制三元 PdBS 合金 MSs 的还原和成核生长来进行的。由于其结构和组成协同作用，所得 PdBS 合金 MSs 表现出显著改善的电催化性能。这一发现扩展了我们对具有预期结构和形态的新型贵金属-类金属-非金属合金的合理设计和定向合成的认识，以用于催化和其他应用。
