This presentation emphasizes the design and synthesis of yolk@shell nanocrystals as advanced photocatalyst models. Structurally, these nanocrystals feature Au nanoparticles as the mobile inner yolk, encapsulated by an outer shell composed of hollow semiconductors. A unique aspect of yolk@shell nanocrystals is the mobility of the central Au nanoparticles, which effectively stir the reactant environment, thereby significantly accelerating catalytic processes. Moreover, the nanoreactor-like void between the yolk and shell fosters enhanced species diffusion, markedly optimizing catalytic reaction kinetics. Furthermore, the formation of a metal/semiconductor interface between the Au yolk and the semiconductor shell ensures efficient charge separation and improved photocatalytic performance. To substantiate these concepts, two exemplary yolk@shell systems developed in our laboratory, including Au@Cu7S4 and Au@CdS, will be presented. These cases exemplify the versatility, efficiency, and potential applicability of yolk@shell nanocrystals, providing essential insights for the rational development of innovative photocatalysts targeting sustainable hydrogen production [1, 2].
