“…As-prepared MW (Figure S5) showed a diffraction pattern positioned at 25.2, 29.6, 33.5, 53, and 59°, which aligns well with the planes (003), (112), (004), (223), and (304) of MgWO 4 (JCPDS no. 52-0390) . To this end, for ZNM@MW, peaks arising from the ZNM core and the MW shell can be well observed.…”

The ability to tune the interfacial region in core–shell nanocomposites with a surface reconstruction as a source for surface energy (de)stabilization is presented. We consider Zn-doped nickel molybdate (NiMoO4) (ZNM) as a core crystal structure and AWO4 (A = Co or Mg) as a shell surface. Based on the density-functional theory method, the interfacial models of Zn-doped NiMoO4@AWO4 (ZNM@AW) core@shell structures are simulated and revealed to undergo surface reconstruction on the (−110) and (−202) surfaces of the AW shells, where the surface degradation of ZNM@MW(−110) is observed. The theoretical simulation is validated against the electrochemical performance of supercapacitor studies. To verify, we synthesize the hierarchical ZNM@AW core@shell semiconductor structured nanocomposites grown on a nickel foam conductive substrate using a facile and green two-step hydrothermal method. The morphology and chemical and electrochemical properties of the hierarchically structured nanocomposites are characterized in detail. The performance of the core@shell is significantly affected by the chosen intrinsic properties of metal oxides and exhibited high performance compared to a single-component system in supercapacitors. The proposed asymmetric device, Zn-doped NiMoO4@CoWO4 (ZNM@CW)||activated carbon, exhibits a superior pseudo-capacitance, delivering a high areal capacitance of 0.892 F cm–2 at a current density of 2 mA cm–2 and an excellent cycling stability of 96% retention of its initial capacitance after 1000 charge–discharge cycles. These fundamental theoretical and experimental insights with the extent of the surface reconstruction sufficiently explain the storage properties of the studied materials.

“…It is clearly that Cd element has substituted some zinc atoms in the ZnWO 4 lattice because the Zn 1– x Cd x WO 4 and pristine ZnWO 4 show similar lattice parameters. 26 This impact is given the credit that the ion-doping facilitates the process of crystallization, which caused rearrangement of lattice ordering in the ZnWO 4 . According to the literature of Huang and Ye, 27 XWO 4 (X is on behalf of Zn and Cd) is a part of a typical ABX 4 structure and monoclinic crystallization ( Figure 2 ).…”

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.

“…O método Hidrotérmico convencional vem sendo utilizado na preparação de diferentes tungstatos na forma de micro e nanocristais com diferentes propriedades eletrônicas (RAJAGOPAL et al 2010). Em relação a síntese do MgWO4, essa rota foi aplicada em 3 artigos (HUANG et al 2018;MENG et al 2019;LI, YANG e MENG, 2009), sendo definido como um processo de obtenção de materiais cristalinos a partir da dissolução de precursores solúveis em solução aquosa sob uma temperatura, pressão e mineralizador (SOMIYA, 2000).…”
