Formation of Yolk–Shell MoS2@void@Aluminosilica Microspheres with Enhanced Electrocatalytic Activity for Hydrogen Evolution Reaction

The development of low-cost electrode materials with enhanced activity and favorable durability for hydrogen evolution reactions (HERs) is a great challenge. MoS2 an effective electrocatalyst unique layered structure. In addition, aluminosilica shells can not only provide more hydroxyl groups but also improve the catalyst as protective shell. Herein, we have designed hard-template route to synthesize porous yolk–shell MoS2@void@Aluminosilica microspheres in NaAlO2 solution. alkaline solution directly etch silica (SiO2) hard templates on surface form outer electrocatalytic results confirm that exhibit higher HERs lower overpotential (104 mV at current density −10 mA cm−2) greater stability than microspheres. superior attributed structure yolk@void@shell geometric construction, protection shell, number active sites offered by their nanosheet subunits. design new strategy may set up method preparing other excellent HER materials.
