چکیده
Developing non-noble metal photocatalysts for efficient photocatalytic hydrogen evolution is crucial exploiting renewable energy. In this study, a photocatalyst of Ni2P/CdS nanorods consisting cadmium sulfide (CdS) (NRs) decorated with Ni2P nanoparticles (NPs) was fabricated using an in-situ solvothermal method red phosphor (P) as the P source. NPs were tightly anchored on surface CdS NRs to form core-shell structure well-defined heterointerface, aiming achieve highly H2 generation. The as-synthesized 2%Ni2P/CdS exhibited significantly improved rate 260.2 ?mol?h?1, more than 20 folds higher that bare NRs. Moreover, demonstrated excellent stability, even better Pt/CdS performance enhancement ascribed interfacial Schottky junction between and accompanying fast effective photogenerated charge carriers’ separation transfer. This work provides new strategy designing replace noble catalysts water splitting.

In this paper, we demonstrate a facile design of ZnS-based heterostructures tailored by versatile glucose-derived carbon ensembles, including carbon dots (CDs) and thin carbon shells, via hydrothermal synthesis. Tuning the content of glucose allows interesting and simple conversion from CDs to carbon shells on the surfaces of ZnS nanospheres. The as-formed ZnS/carbon nanocomposites exhibit an e...

N-doped mesoporous TiO2 nanorods were fabricated by a modified and facile sol-gel approach without any templates. Ammonium nitrate was used as a raw source of N dopants, which could produce a lot of gasses such as N2, NO2, and H2O in the process of heating samples. These gasses were proved to be vitally important to form the special mesoporous structure. The samples were characterized by the po...
متن کاملEnhanced Photocatalytic Hydrogen Evolution by Loading Cd0.5Zn0.5S QDs onto Ni2P Porous Nanosheets
Ni2P has been decorated on CdS nanowires or nanorods for efficient photocatalytic H2 production, whereas the specific surface area remains limited because of the large size. Here, the composites of Cd0.5Zn0.5S quantum dots (QDs) on thin Ni2P porous nanosheets with high specific surface area were constructed for noble metal-free photocatalytic H2 generation. The porous Ni2P nanosheets, which wer...

Aligned TiO2 nanotube layers (TiNTs) grown by self-organizing anodization of a Ti-substrate in a fluoride-based electrolyte were decorated with graphitic-phase C3N4 (g-C3N4) via a facile chemical vapor deposition approach. In comparison with classical TiO2 nanotubes (anatase), the g-C3N4/TiNTs show an onset of the photocurrent at 2.4 eV (vs. 3.2 eV for anatase) with a considerably high photocur...
