With the escalating demand for clean and sustainable energy sources, hydrogen emerges as a paramount contender, necessitating efficient and innovative production methods of water splitting. This review ventures into the burgeoning field of yolk@shell nanostructures and their pivotal role in advancing water splitting technologies. The synthesis, unique properties, and multifaceted applications of yolk@shell nanostructures across electrocatalytic (EC), photocatalytic (PC), and photoelectrocatalytic (PEC) water splitting processes are evaluated. We start with a brief introduction to various synthetic strategies, including template-assisted formation, the Kirkendall effect, galvanic replacement, and Ostwald ripening, each contributing to the tailored construction of yolk@shell nanostructures with enhanced catalytic efficiencies. Highlights are put on the significant advancements in utilizing these nanostructures to optimize EC activities, PC hydrogen production rates, and PEC water splitting efficiency. Furthermore, we address the challenges of integrating hydrogen generation with valuable compound production, near-infrared photoactivity, and seawater splitting, underscoring the necessity for innovation and the potential for yolk@shell nanostructures in diversifying energy conversion systems. Through a comprehensive analysis, this review not only showcases the current developments but also outlines prospects, emphasizing the critical importance of yolk@shell nanostructures in the sustainable energy landscape.

Many industrial processes such transesterification of fatty acid for biodiesel production, soap manufacturing and biosynthesis of ethanol generate glycerol as a major by‐product that can be used to produce commodity chemicals. Photocatalytic transformation of glycerol is an enticing approach that can exclude the need of harsh oxidants and extraneous thermal energy. However, the product yield and selectivity remain poor due to low absorption and unsymmetrical site distribution on the catalyst surface. Herein, tellurium (Te) nanorods/nanosheets (TeNRs/NSs) wrapped potassium‐doped carbon nitride (KCN) van der Waal (vdW) heterojunction (TeKCN) is designed to enhance charge separation and visible‐NIR absorption. The iridium (Ir) single atom sites decoration on the TeKCN core‐shell structure (TeKCNIr) promotes selective oxidation of glycerol to glyceraldehyde with a conversion of 45.6% and selectivity of 61.6% under AM1.5G irradiation. The catalytic selectivity can reach up to 88% under 450 nm monochromatic light. X‐ray absorption spectroscopy (XAS) demonstrates the presence of undercoordinated IrN2O2 sites which improved catalytic selectivity for glycol oxidation. Band energies and computational calculations reveal faile charge transfer in the TeKCNIr heterostructure. EPR and scavenger tests discern that superoxide (O2•−) and hydroxyl (•OH) radicals are prime components driving glycerol oxidation.
