Richardson and Saha‐Langmuir plots made in the region of the transformation provided values for the work function eφ and the quantity e(φ-I). Small stresses up to 25 g/mm, which were externally applied to an almost exhausted filament, did not influence the positive‐ion or electron ...
锐钛矿TiO_2能带结构吸收光谱运用第一性原理,对C掺杂锐钛矿相TiO2的电子结构进行了研究,从能带结构理论解释了C掺杂TiO2吸收光谱的一些实验现象.发现在C掺杂后的锐钛矿相TiO2的禁带宽度增大,并且在带隙中出现了杂质能级,这些杂质能级主要是由C 2p轨道上的电子构成的,它们之间是独立的,正是这些独立的杂质能级使TiO2...
It comprises minor amounts of MnO and TiO2 (~ 0.45 and ~ 0.59 wt.%, respectively). Mg#(molar Mg/Mg + Fe) values are variable and range between 0.55 and 0.61 (inner areas of the crystals) and 0.42–0.44 (outer regions of the crystals). The Raman spectrum of augite is...
To quantitively assess the spatial confinement effect, we constructed a series of REMs using Ti membranes as the conductive substrates (Supplementary Fig.2). The interconnected pore network served as water channels, on which defective TiO2nanosheets were fabricated as electrocatalysts (Supplementary Fig.3...
Considering the amount of TiO2 incorporated in Si-PFE-TiO2 (∼0.92 g/m2), its photoactivity outperforms other recently reported TiO2-containing coatings. Moreover, compared with anatase nano-TiO2, Si-PFE-TiO2 coating showed higher antimicrobial effects against Gram-positive and Gram-negative ...
various Gram-negative/positive bacteria, fungi, algae etc. [74]. The mechanism of TiO2 photocatalytic disinfection is still not so clear and a lot of debate is still going on for the exact mechanism of action. However, the killing mechanism is most accepted process of antimicrobial effect in ...
In a study in which TiO2 additive was used, they stated that the fuel cell performance of the membrane increased with the additive material and that TiO2 additive had a positive effect on proton conductivity [48]. Cali et al. stated that the BP additive increased the proton conductivity and ...
aSEM-micrograph,bXRD-pattern,cDR spectrum (with bandgap evaluation), anddphenol degradation curve of P25 TiO2 Full size image Properties of soil solutions and their possible effects on the behavior of TiO2NPs The pH, IS, COD, and inorganic ion content of regosol and chernozem soil solutions ...
The reverse water gas shift reaction can be considered as a promising route to mitigate global warming by converting CO2 into syngas in a large scale, while it is still challenging for non-Cu-based catalysts to break the trade-off between activity and se
Here, a disordered mesoporous and highly defected titanium dioxide (dom-TiO2) electrocatalyst for the oxidation of hydroxide ion was prepared via ligand-assisted evaporation-induced self-assembly. The (dom-TiO2) electrocatalyst showed significant electrocatalytic performance for the oxidation of hydroxide...
