چکیده
Herein, we have successfully prepared self-doped carbon dots with nitrogen elements (NCD) in a simple one-pot hydrothermal carbonization method, using L-histidine as new precursor. The effect of as-prepared was studied for photoelectrochemical (PEC) water splitting by decorating NCDs upon TiO2 nanorods systematically changing the loading time from 2 h to 8 (TiO2@NCD2h, TiO2@NCD4h, TiO2@NCD6h, and TiO2@NCD8h). successful on confirmed FE-TEM Raman spectroscopy. TiO2@NCD4h has shown photocurrent density 2.51 mA.cm−2, 3.4 times higher than pristine TiO2. Moreover, exhibited 12% applied bias photon-to-current efficiency (ABPE) detailed IPCE, Mott–Schottky, impedance (EIS) analyses revealed enhanced light harvesting property, free carrier concentration, charge separation, transportation introduction obtained results clearly portray key role improving PEC performance, providing insight into development highly competent based photoanodes splitting.

Controlled fabrication of Sn/TiO2 nanorods for photoelectrochemical water splitting
In this work, we investigate the controlled fabrication of Sn-doped TiO2 nanorods (Sn/TiO2 NRs) for photoelectrochemical water splitting. Sn is incorporated into the rutile TiO2 nanorods with Sn/Ti molar ratios ranging from 0% to 3% by a simple solvothermal synthesis method. The obtained Sn/TiO2 NRs are single crystalline with a rutile structure. The concentration of Sn in the final nanorods ca...
متن کاملHemin/Au nanorods/self-doped TiO2 nanowires as a novel photoelectrochemical bioanalysis platform.
As a recently developed detection technique, photoelectrochemical (PEC) measurement has received extensive attention. However, owing to the lack of a comprehensive approach to engineer the photo-generated carriers, the performance is still limited. As an example, a significant use of PEC measurement might be in understanding the roles of glutathione in physiological and pathological processes. ...

Au nanostructure-decorated TiO2 nanowires exhibiting photoactivity across entire UV-visible region for photoelectrochemical water splitting.
Here we demonstrate that the photoactivity of Au-decorated TiO2 electrodes for photoelectrochemical water oxidation can be effectively enhanced in the entire UV-visible region from 300 to 800 nm by manipulating the shape of the decorated Au nanostructures. The samples were prepared by carefully depositing Au nanoparticles (NPs), Au nanorods (NRs), and a mixture of Au NPs and NRs on the surface ...
