Ag–Au core–shell triangular nanoprisms (Ag@Au TNPs) have aroused extensive research interest in the field of hydrogen evolution reaction (HER) due to their strong plasmon effect and stability. Here, Ag@Au TNPs were fabricated by the galvanic-free replacement method. Then, we loaded them on protonated g-C3N4 nanoprisms (P–CN) by the electrostatic self-assembly method as an efficient plasmonic photocatalyst for HER. The hydrogen production rate of Ag@Au TNPs/P–CN (4.52 mmol/g/h) is 4.1 times higher than that of P–CN (1.11 mmol/g/h) under simulated sunlight irradiation, making it the most competitive material for water splitting. The formed Schottky junction helps to trap the hot electrons generated from Ag@Au TNPs, and the well-preserved tips of the Ag@Au TNPs can effectively generate an electromagnetic field to inhibit the photogenerated electron–holes pairs recombination. This study suggests that the rational design of Ag@Au TNPs by the galvanic-free replacement method is an effective co-catalyst for HER and boosting the additional combination of plasmonic metals and catalyst metals for the enhancement to HER.

<p>Rational design of active oxygen evolution reaction (OER) catalysts is critical for the overall efficiency of water electrolysis. OER reactants and products’ differing spin states is one of causes to slow OER kinetics. Thus, spin conservation plays a crucial role in enhancing OER performance. In this work, we design ferromagnetic (FM)–antiferromagnetic (AFM) Fe<sub>3</sub>O<sub>4</sub>@Ni(OH)<sub>2</sub> core–shell catalysts. The interfacial FM–AFM coupling of these catalysts facilitates selective removal of electrons with spin direction opposing the magnetic moment of FM core, improving OER kinetics. The shell thickness is found critical in retaining the coupling effect for OER enhancement. The magnetic domain structure of the FM core also plays a critical role. With a multiple domain core, the applied magnetic field aligns the magnetic domains, optimising the electron transport process. A significant enhancement of OER activity is observed for the multiple domain core catalysts. With a single domain FM core with ordered magnetic dipoles, the spin-selective electron transport with minimal scattering is facilitated even without an applied magnetic field. We therefore draw a magnetism/OER activity model that depends on two main parameters: interfacial spin coupling and domain structure. Our findings provide new design principles for active OER catalysts.</p>
