“…The way of controlling the morphology were rarely used in the industrial production, until now, which is probably because a good deal of photo-generated carriers are excited, which irregularly generate taunt the recombination of carriers and further impose restrictions on photocatalytic performance . Composite photocatalysts about ZnWO 4 by means of constructing heterostructures have been reported, for instance, CdS/Zn 1– x Cd x WO 4 , BiOI/ZnWO 4 , LAS/ZnO/ZnWO 4 . Benefiting from heterostructure effects, admirable visible-light photocatalytic property of these composited materials can be achieved.…”

Fabricating nanostructures and doping engineering are beneficial to tailor the photocatalytic activity of semiconductor materials, and the semiconducting photocatalysis is deemed to be one of the potential protocols to handle the environmental pollution and energy crisis issues. Herein, rodlike Cd-doped ZnWO 4 Zn 1– x Cd x WO 4 nanoarchitectures were triumphantly prepared by a template-free strategy. The crystal structure, chemical state, optical, and photocatalytic features of the Zn 1– x Cd x WO 4 nanoarchitectures were studied using a variety of characterizations. The Zn 1– x Cd x WO 4 nanoarchitectures exhibit glorious photocatalytic performance compared with pristine ZnWO 4 for the degradation of methyl orange in sewage. Mechanistic studies were executed for getting insights into the photocatalytic degradation process, and the remarkable photocatalytic property of the doped ZnWO 4 nanoarchitectures is attributed to the boosted optical absorptive efficiency and the valid segregation and transmission of photogenerated charge carriers deriving from doping effects. The doped nanoarchitectures of this work have promising applications in the territories such as environment and energy chemistry, and the insight proposed in this work will contribute to develop other functionalized nanoarchitectures.

“…Huang et al [ 36 ] synthesized hierarchical Fe 3+ -modified BiOCl micro-flowers by a one-step solvothermal method, which demonstrates that Fe 3+ -modified BiOCl plays an important role in promoting the degradation of the gaseous decomposition acetaldehyde. Though Cd 2+ is highly toxic [ 37 ], Cd 2+ ions not only change the properties of the original semiconductors but also has a great influence on the whole catalytic activity with the increase of doping amount [ 38 , 39 ]. In addition to controlling the growth of crystal form and the size of microcrystalline, the surface structure, spectral response range and bandgap energy of the original semiconductor are further changed by introducing Cd 2+ ions via chemical method [ 40 ].…”

Uniform flowerlike microspheres Cd2+/Fe3+ co-doped BiOBr were prepared with the aid of the microwave hydrothermal process. The results indicate that the degradation performance of Bi1−xCdxOBr and Bi1−xFexOBr are 1.31 and 2.05 times that of BiOBr for RhB, respectively. Moreover, the novel Cd2+/Fe3+ co-doped BiOBr photocatalysts with ~0.42 eV impurity bands presented remarkably enhanced photocatalytic activities with being 3.10 times that of pure BiOBr, by achieving e−/h+ efficient separation and narrowed bandgap with the ions synergistic effect of Cd2+ and Fe3+. Based on DFT insights, the photodegradation mechanism was systematically studied that the conversion of multivalent Fe3+ ions promoted the production of •O2−, and Cd2+ ions worked as electron transfer mediators, which elucidated that the •O2− and h+VB mainly participated in the catalytic reaction. The experimental and theoretical results show that the synergistic effects of multi-ion doping have great potential in the field of photocatalysis.
