The fast growing interest in portable electronic devices and electric vehicles has stimulated extensive research high performance energy storage devices, such as supercapacitors. Nanostructured electrodes can achieve electrochemical performances supercapacitors owing to their surface atom ratio, tuneable texture unique size-dependent properties that afford effective electrolyte diffusion improved charge transportation during charging–discharging. This review reports on the recent progress...
A novel nanocomposite of iron oxide and silicate, prepared through a reaction between solution salt dispersion Laponite clay, was used as catalyst for the photoassisted Fenton degradation azo-dye Orange II. This is much cheaper than Nafion-based catalysts, our results illustrate that it can significantly accelerate II under irradiation UV light (λ = 254 nm). An advantage its long-term stability confirmed using multiple runs in The effects H2O2 molar concentration, pH, wavelength power light,...
A novel bentonite clay-based Fe-nanocomposite (Fe-B) was successfully developed as a heterogeneous catalyst for photo-Fenton discoloration and mineralization of an azo-dye Orange II. X-ray diffraction (XRD) analysis clearly reveals that the Fe-B nanocomposite mainly consists Fe2O3 (hematite) SiO2 (quartz) crystallites, Fe concentration determined by X-reflective fluorescence (XRF) is 31.8 wt %. The catalytic activity evaluated in II presence H2O2 UVC light (254 nm). It found optimal dosage...
Four heterogeneous catalysts containing Fe including a bentonite-clay-based nanocomposite (Fe-B), hematite (α-Fe2O3), amorphous FeOOH, and calcined FeOOH (denoted as FeOOH-M) were employed for the photo-Fenton discoloration mineralization of 0.2 mM Orange II in presence 10 H2O2 8 W UVC at two different initial solution pH values (3.0 6.6). It was found that, an 3.0, their photocatalytic activities follow order Fe-B > FeOOH-M α-Fe2O3. When nanocomposite, used catalysts, both homogeneous...
Ecosystem services and ecological risk prevention are important factors that influence for sustainable socio-economic development. In recent years, fewer studies, practices have been conducted on the value of ecosystem management in larger regions, mechanisms their interactions not adequately investigated. The central southern region China is a stage high-quality development, Hunan Province this used as an example to investigate interaction mechanism between service (ESV) landscape (LER)as...
Firmiana danxiaensis (F. danxiaensis) is a special native species with narrow distribution. More than 90 % of the plant in genus that F. belongs to are rare The main distribution area Mount Danxia, representative China Danxia where many endemic landform have been bred. We carried out gap analysis by overlapping nature reserves potential habitat danxiaensis. results show that: (1) 6,255.28 km2 simulated Biomod2 ensemble model and 4,114.19 Maxent, respectively, which accounted for 3.48 2.29...
TiO2 in anatase crystal phase is a very effective catalyst the photocatalytic oxidation of organic compounds water. To improve recovery rate photocatalysts, which most cases are fine powder form, chemical vapor deposition (CVD) method was used to load onto bigger particle support, silica gel. The amount titania coating found depend strongly on synthesis parameters carrier gas flow and time. XPS nitrogen ads/desorption results showed that particles generated from CVD were distributed external...
The surface chemistry of ordered mesoporous carbon CMK-3 was successfully modified by heat treatment in ammonia gas at a temperature 1173 K, without destroying its hexagonally structure significantly. adsorption kinetics and equilibrium three commercial anionic dyes, i.e., orange II, reactive red 2 (RR2), acid black 1(AB1), on the novel functionalized were investigated. It found that ammonia-tailored showed much higher uptake rate than activated carbon, due to desirable electron-donating...
Coupling land use and climate change under shared socioeconomic pathway representative concentration (SSP–RCP) scenarios can provide more accurate predictions of water supply risks, thereby supporting decision-making for spatial planning with a focus on adaptation. Climate exhibits temporal differences. To meet the requirements planning, further research is needed to assess risks at different basin or regional scales. In this study, we selected four SSP–RCP analysis, considering scale...
Abstract This study systematically investigates the spatio-temporal distribution, influential factors, and conservation significance of 413 traditional villages in Xiangxi, China. Employing methods such as ArcGIS spatial analysis, geographic statistical historical literature review, this work meticulously delineates intricate interplay natural, societal, cultural elements shaping evolution village distributions. As pillars China's rich culture, these encapsulate profound historical,...
There is a long-standing conjecture in Hamiltonian analysis which claims that there exist at least n geometrically distinct closed characteristics on every compact convex hypersurface R2n with n≥2. Besides many partial results, this has been completely solved only for n=2. In article, we give confirmed answer to n=3. order prove result, establish first new resonance identity Σ when the number of finite. Then, using and earlier techniques index iteration theory, mentioned multiplicity result...
