Enhancing Charge Separation in Metallic Photocatalysts: A Case Study of the Conducting Molybdenum Dioxide

“…32-0671, space group: P2 1 /n, a 0 = 5.6062 Å, b 0 = 4.8596 Å, c 0 = 5.5371 Å). [12] The as-prepared MoO 2 are aggregated nanoparticles (Figure 1b). Its high-resolution transmission electron microscopy (HRTEM) image further shows a lattice fringe of 0.246 nm, corresponding to the (111) crystal facet of MoO 2 (Figure 1b, inset).…”

“…The apparent rate constant for the photodecomposition of Rhodamine B was calculated by the equation of k = In(C 0 /C)/t. [12,36] The method of active species trapping experiment is identical with the photocatalytic tests. The concentrations of p-benzoquinone and disodium ethylenediaminetetraacetate (Na 2 -EDTA) are 2 × 10 -3 m.…”

“…Subsequently, the solution was transferred to a 25 mL Teflon-lined stainless steel autoclave and heated at 180 °C for 12 h. After the reaction, the product was collected via centrifugation at 14 000 rpm for 1 h. After being washed with distilled water several times, the product was dried in a vacuum oven overnight. [12] Preparation of MoO 2 -HTCC Composites: 0.5 g of glucose and 1.7 g of AHM were dissolved in 20 mL of distilled water. Subsequently, the solution was transferred to a 25 mL Teflon-lined stainless steel autoclave and heated at 180 °C for 8 h. After the reaction, the product was collected via centrifugation at 14000 rpm for 1 h. After being washed with distilled water several times, the product was dried in a vacuum oven overnight.…”

Carbon-coated MoO2 dispersed in three-dimensional graphene aerogel for lithium-ion battery

“…[9,10] However, large change in volume can collapse the structure, which reduces MoO 2 performance, like high capacity and stability during charge and discharge. In order to overcome this problem, MoO 2 with different morphology have been synthesized, such as MoO 2 nanospheres, [13] ordered mesoporous MoO 2 , [3] tremella-like MoO 2 , [11] MoO 2 nanoparticles, [12] MoO 2 nanofibers [14] and ultrafine MoO 2 nanosheets. [15] Besides, carbonaceous materials such as amorphous carbon, [13,16] carbon nanotubes (CNT) [17,18] and graphene [19][20][21] have been used to incorporate with MoO 2 .…”

Facile synthesis of monodisperse hierarchical MoO2 porous spheres for high-performance Li-ion battery

“…Molybdenum dioxide (MoO 2 ) has attracted much attention as an anode material for lithium ion battery because of its high theoretical capacity (838 mA h g -1 ) and affordable cost [1][2][3][4]. Beyond that, its rich chemistry characters, associated with multiple valence states, low electrical resistivity, high chemical stability and high density, provide additional necessary guarantees for excellent lithium storage application [5,6].…”
