Influence of lattice integrity and phase composition on the photocatalytic hydrogen production efficiency of ZnS nanomaterials.

چکیده
Ambient S annealing was adopted to regulate the crystallinity of a ZnS microsphere, which resulted in a significant improvement in the photocatalytic hydrogen production activity (PHPA). Moreover, with S ambient treatment, wurtzite ZnS showed better PHPA than sphalerite ZnS, possibly because the inter-polar electric field of the wurtzite phase could promote the separation of photo-excited electron-hole pairs.

متن کاملPhotocatalytic outcomes for methylene blue degradation from CTAB mediated mesoporous ZnS, synthesized with an insoluble precursor in ethanol media
The aim of the present study is to demonstrate how mesoporous nanostructures of Zinc Sulfide (ZnS) will precipitate in an ethanol media in spite of negligible solubility of Sodium Nitrate (Na2S), which is role-played as sulfur precursor. On the following, the role of such synthesizing method on the photocatalytic behavior of ZnS mesoporous nanostructures has been investigated. Characterization ...
متن کاملCarbon-ensemble-manipulated ZnS heterostructures for enhanced photocatalytic H2 evolution.
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...

متن کاملUnderstanding divergent behaviors in the photocatalytic hydrogen evolution reaction on CdS and ZnS: a DFT based study.
It has been a long time that divergent behaviors were observed in many photocatalytic hydrogen evolution reactions (HER) on CdS and ZnS although the two photocatalysts have similar compositions and structures. For example, CdS itself is inactive and loading of cocatalysts is indispensable to achieve high efficiency of hydrogen evolution, but the reverse is true for ZnS. The underlying reasons a...
