2021年5月24日 · Colored charge-transfer complexes can be formed by the association between electron-rich donor and electron-deficient acceptor molecules, bringing about the narrowing of HOMO–LUMO energy gaps so that they become capable of harnessing visible light.

2023年2月28日 · Our results show that ligand interlocking as a catenane steers the ORR selectivity to H 2 O as the major product via the 4e – pathway, rivaling the selectivity of Pt, and boosts the onset potential by 130 mV, the mass activity by 1.8 times, and the turnover frequency by 1.5 fold as compared to the noninterlocked counterpart.

Our results demonstrate that the binder-free Pt, Ru, and Ni NPs supported on a few-layer graphene generated using the LANP strategy can serve as practical, active, and robust electrocatalysts for water-splitting reactions in advanced electrolyzer technology.
