Bismuth oxide and its derivatives are promising materials that have applications varying from catalysis to energy-storage devices. Most of these applications benefit from the creation of crystalline nanostructures. Herein, we present a simple and fast polymer-assisted precipitation method to synthesize various crystalline bismuth oxide nanomaterials, including bismuth oxide (BiO) microrods, bismuth-transition metal mixed oxide (BiMO, M = V, Cr, Mo, or W) nanoparticles/rods, and bismuth oxyhalide (BiOX, X = Cl, Br, or I) nanoplates. All these materials are semiconductors with bandgaps in the range of 1.76-3.43 eV. This strategy can also be used to fabricate nanostructured composites (e.g., bismuth vanadate nanoparticles on BiOX nanosheets), copper oxide nanoparticles, and potentially other metal oxide nanomaterials.
氧化铋及其衍生物是很有前景的材料，其应用范围从催化到储能设备。这些应用大多受益于结晶纳米结构的形成。在此，我们提出一种简单快速的聚合物辅助沉淀法，用于合成各种结晶氧化铋纳米材料，包括氧化铋（BiO）微棒、铋 - 过渡金属混合氧化物（BiMO，M = V、Cr、Mo或W）纳米颗粒/棒以及卤氧化铋（BiOX，X = Cl、Br或I）纳米片。所有这些材料都是半导体，其带隙在1.76 - 3.43 eV范围内。该策略还可用于制备纳米结构复合材料（如BiOX纳米片上的钒酸铋纳米颗粒）、氧化铜纳米颗粒以及潜在的其他金属氧化物纳米材料。
