“…In the past decade, 1D nanostructures have been extensively investigated in the photocatalysis application due to the short diffusion length of quantum particles, facile strain relaxation on flexible substrates as well as easy separation from aqueous suspension only by sedimentation . According to whether the templates are employed or not, the strategies for the synthesis of 1D Bi 2 MoO 6 could be classified into the direct and indirect approaches.…”

Highly active photocatalysts driving chemical reactions are of paramount importance toward renewable energy substitutes and environmental protection. As a fascinating Aurivillius phase material, Bi 2 MoO 6 has been the hotspot in photocatalytic applications due to its visible light absorption, nontoxicity, low cost, and high chemical durability. However, pure Bi 2 MoO 6 suffers from low efficiency in separating photogenerated carriers, small surface area, and poor quantum yield, resulting in low photocatalytic activity. Various strategies, such as morphology control, doping/defect-introduction, metal deposition, semiconductor combination, and surface modification with conjugative π structures, have been systematically explored to improve the photocatalytic activity of Bi 2 MoO 6 . To accelerate further developments of Bi 2 MoO 6 in the field of photocatalysis, this comprehensive Review endeavors to summarize recent research progress for the construction of highly efficient Bi 2 MoO 6 -based photocatalysts. Furthermore, benefiting from the enhanced photo catalytic activity of Bi 2 MoO 6 -based materials, various photocatalytic applications including water splitting, pollutant removal, and disinfection of bacteria, were introduced and critically reviewed. Finally, the current challenges and prospects of Bi 2 MoO 6 are pointed out. This comprehensive Review is expected to consolidate the existing fundamental theories of photo catalysis and pave a novel avenue to rationally design highly efficient Bi 2 MoO 6 -based photocatalysts for environmental pollution control and green energy development.

“…For example, the photocatalytic hydrogen production of Bi 2 WO 6 loaded with 1 wt.% of Pt was observed in an aqueous methanol solution under the illumination of a 450-W high-pressure mercury lamp [186]. So far, the Bi 2 WO 6 photocatalyst is mainly used for organic pollutant degradation and the application for the solar-hydrogen production is still rare [41].…”

“…For example, binary oxides such as WO 3 and MoO 3 are photocatalytic materials for the oxygen evolution reaction (OER), while their chalcogenides such as WS 2 and MoS 2 are excellent cocatalysts for the hydrogen evolution reaction (HER) [36][37][38][39]. By incorporating another metal cation into the binary oxides, ternary tungsten-and molybdenumbased materials such as CuWO 4 [40], Bi 2 WO 6 [41], and Bi 2 MoO 6 [42], with various optoelectronic properties can be achieved. Moreover, other more complicated quaternary semiconductors such as RbNbWO 6 , RbTaWO 6 , CsNbWO 6 , and CsTaWO 6 can also be generated [43], providing more opportunities for the rational design of materials for efficient solar fuel production.…”

Semiconductor-based solar water splitting is regarded as one of the most promising technologies for clean hydrogen production. The rational design of semiconductor materials is critically important to achieve high solar-to-hydrogen (STH) conversion efficiencies towards practical applications. A rich family of tungsten-and molybdenum-based materials have been developed as both photocatalysts and cocatalysts for solar-hydrogen production in the past years, providing more opportunities to achieve high solar-to-hydrogen (STH) efficiencies. In this review article, we comprehensively review the recent progress of tungsten-and molybdenum-based materials for solar-hydrogen production. In particular, the strengths and drawbacks of each material system are critically discussed, followed by an overview of the emerging strategies to improve their performances. Finally, the key challenges and possible research directions of tungsten-and molybdenum-based materials are presented, which would provide useful information for the design of efficient semiconductor materials for solar-hydrogen production.

Innovative and Cost-Efficient BiOI Immobilization Technique on Ceramic Paper—Total Coverage and High Photocatalytic Activity

et al. 2020

In the present work, visible light active bismuth oxyiodide (BiOI) was immobilized on a commercial, non-conductive support (an Al2O3 based ceramic paper) using a novel two-step spray coating technique and investigated with different characterization methods (e.g., SEM, Raman, XPS). Our main goal was to eliminate the separation costs after the photocatalytic measurement and investigate the chemical relevance and opportunity to use this technique in the industry. Our as-prepared uniform BiOI layer had similar properties to the well-known reference BiOI powder. The Raman and XPS measurements confirmed that the enriched amount of the surface iodine defined the color and as well the band gap of the BiOI layer. The durable BiOI layers have prominent photocatalytic activity under UV and visible light irradiation as well. The scale-up procedure proved that the designed BiOI coated paper was reusable and potentially applicable in the industry by straightforward scale-up, which is due to the elaborated non-conventional BiOI coverage estimation method. This immobilization technique could open several opportunities for immobilizing many other visible light active photocatalysts with simple materials and low cost.
