Hierarchical nanosheet-based Bi₂MoO₆ microboxes for efficient photocatalytic performance

Abstract

Hierarchical nanosheet-based Bi2MoO6 microboxes are synthesized by a facile template-assisted strategy. MnCO3 microcubes are prepared as templates for the growth of Bi2MoO6 nanosheets and then etched by using HCl aqueous solution. In particular, the hierarchical Bi2MoO6 microboxes provide a large surface area, and facilitate visible-light absorption and charge separation, demonstrating efficient photocatalytic performance. This work highlights a new method to prepare hollow nanosheet-built Bi2MoO6 structures with high photocatalytic properties.

Modulation of Bi2MoO6‐Based Materials for Photocatalytic Water Splitting and Environmental Application: a Critical Review

“…The template‐assisted method is another classically synthetic method for 3D hollow nanostructures. In this regard, carbon spheres and acid/alkali‐nonresistant inorganic materials are often utilized as templates due to their easy manipulation and cost efficiency . For example, cage‐like Bi 2 MoO 6 hollow spheres have been successfully prepared with colloidal carbon spheres as the templates .…”

Selective synthesis of visible light active γ-bismuth molybdate nanoparticles for efficient photocatalytic degradation of methylene blue, reduction of 4-nitrophenol, and antimicrobial activity

“…Among them, bismuth molybdates, as novel semiconductor photocatalysts, have been determined to have an excellent performance in solar-light-mediated systems, showing great potential in applications such as water splitting and environmental purication. 24 Bismuth oxides exhibit both a high oxide ion conductivity and an electrocatalytic activity for the interconversion of molecular O 2 and ionic O 2 À at low temperature (300-500 C) and thus have an important potential for oxygen generation. 24,25 The general chemical formula of bismuth molybdate is Bi 2 O 3 $nMoO 3 , where n ¼ 3, 2 or 1 which are corresponding to a (Bi 2 Mo 3 O 12 ), b (Bi 2 Mo 2 O 9 ), and g (Bi 2 MoO 6 ) phases respectively.…”

Facile Synthesis of Bi2MoO6 Microspheres Decorated by CdS Nanoparticles with Efficient Photocatalytic Removal of Levfloxacin Antibiotic

“…In recent years, the semiconductor-based photocatalysis as a green oxidation technology, has made significant developments for treating water pollutions [3][4][5][6][7][8][9][10]. Bismuth (III)-based semiconductors (e.g., BiOX (X = Cl, Br, I) [11][12][13], Bi 2 MoO 6 [14][15][16][17], and Bi 2 WO 6 [18]) have been emerging as kinds of high-efficiency photocatalysts. Among them, Bi 2 MoO 6 as a good visible-light-driven (VLD) photocatalyst, has been one of the focal research points in the area of photocatalysis.…”

“…Unlike the popular TiO 2 , which only can respond to the ultraviolet light, Bi 2 MoO 6 (Eg ≈ 2.5-2.8 eV) is active in the visible-light region. However, Bi 2 MoO 6 still suffers from the narrow range of sunlight response and fast electron-hole recombination [15][16][17]19]. Intriguingly, the fabrication of semiconductor heterojunctions is a crucial way to obtain superior photocatalysts [20].…”
