Graphical abstract
The hetero-nanorods based on multiple valencies in one material bring about a remarkable synergistic effect and markedly enhanced electrocatalytic activity for the reduction of H2O2. Taking advantage of the electro-reduction of hetero-nanorods and the high conductivity and large surface area of GS, MM-HNRS/GS exhibits excellent sensor performance in non-enzymatic and noble metal-free detection of H2O2. | Phenylalanine-functionalized graphene quantum dot-silicon nanoparticle composite as an anode material for lithium ion batteries with largely enhanced electrochemical performance Original Research Article

Graphical abstractWe reported a facile synthesis of phenylalanine-functionalized graphene quantum dots via pyrolysis of the mixture of citric acid and phenylalanine and its use for fabrication of phenylalanine-functionalized graphene quantum dots-silicon nanoparticles (termed PF-GQD@SiNP). The introduction of PF-GQD greatly improves the electrical conductivity and effectively prevents direct contact of silicon nanoparticles with the electrolyte. Owing to unique structure of PF-GQD, the PF-GQD@SiNP electrode provides an excellent electrochemical performance for lithium ion batteries.
