| Research Abstract |
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.
