L10-FePd/alpha-Fe nanocomposite magnets with various hard/soft volume fractions were formed by annealing Pd/gamma-Fe2O3 heterostructured nanoparticles (NPs) and pure Pd NPs. The sample with a hard/soft volume ratio of 82/18 formed by annealing at 773 K had the largest maximum energy product (10.3 MGOe). The formation of an octahedral shape was found to further increase the magnetic properties. As for the photocatalysts for overall water splitting under visible light, when the size tuned Rh NPs were applied for use as cocatalysts in a photocatalyst (solid solution of GaN and ZnO), it was demonstrated that smaller Rh cores gave higher activity than the larger ones. Then, the CoxMn3-xO4 mixed oxide NPs were studied as a new cocatalyst for photocatalytic water oxidation. The photocatalytic activity of the CoxMn3-xO4 NPs-loaded photocatalyst for overall water splitting was 2.6 times higher than that without the CoxMn3-xO4 NPs.

L10-FEPD/Alpha-FE纳米复合磁铁具有各种硬/软体积分数，通过退火PD/GAMMA-FE2O3异质结构纳米颗粒（NPS）和纯PD NP形成。通过在773 K处退火而形成的硬/软容量比为82/18的样品具有最大的最大能量产物（10.3 mgoe）。发现八面体形状的形成进一步增加了磁性。至于在可见光下进行总体水分裂的光催化剂，当将调谐的RH NP施加在光催化剂中（GAN和ZnO的实心溶液）中时，将其用作cocatalysts时，证明较小的RH核心的活性比较大的活性更高。然后，研究了Coxmn3-XO4混合氧化物NP作为光催化水氧化的新腔催化剂。如果没有COXMN3-XO4 NP，用于整体水分分裂的Coxmn3-XO4 NPS的光催化剂的光催化活性是2.6倍。
