Electrochemical study of anatase TiO2 in aqueous sodium-ion electrolytes
Published in Biointerface Research in Applied Chemistry
In this paper, a basic electro-analytical study on the behavior of anatase TiO 2 in aqueous NaOH has been presented using cyclic voltammetry technique (CV). The study has explored the possibility of using TiO 2 as anode material for ARSBs in presence of 5 M NaOH aqueous electrolyte. CV profiles show that anatase TiO 2 exhibits reversible sodium ion...
In situ topotactic fabrication of direct Z-scheme 2D/2D ZnO/ZnxCd1-xS single crystal nanosheet heterojunction for effici...
Direct Z-scheme heterojunction can effectively enhance the photocatalytic activity due to its low carrier recombination rate and high redox ability. In this study, a 2D/2D ZnO/ZnxCd1-xS single crystal nanosheet heterojunction is synthesized in situ by topotactic sulfurization/oxidization pyrolysis of Zn/Cd/Al layer double hydroxides (LDHs). Its uni...
Immobilizing Ultrafine PtNi Nanoparticles within Graphitic Carbon Nanosheets toward High-Performance Hydrogenation React...
Immobilization of Pt-based nanoparticles on carbon support is of great significance in catalysis for their superior activity and enhanced durability. Herein, we report for the first time a feasible NaCl template-engaged approach to firmly immobilize PtNi nanoparticles into two-dimensional (2D) graphitic carbon nanosheets (denoted as [email protected] herea...
First principles investigations of the structural, electrical and optical properties of iron-doped zinc oxide (0001) sur...
A first principles density function investigation of the structural, electrical and optical properties of iron-doped ZnO (0 0 0 1) surfaces is conducted by considering the substitutional sites in the three relaxed ZnsbndO bilayers and the interstitial site in the centre of the octahedron surrounded by zinc atoms. Calculations are performed with the...
Nanocomposite Film Containing Fibrous Cellulose Scaffold and Ag/TiO2 Nanoparticles and Its Antibacterial Activity
Cellulose is a natural polymer that is widely used in daily life, but it is susceptible to microorganism growth. In this study, a simple sol-gel technique was utilized to incorporate the cellulose scaffold with Ag/TiO2 nanoparticles. The morphology and crystal structure of the as-prepared Ag/TiO2/cellulose composite film were characterized using sc...
Selective reduction leaching of vanadium and iron by oxalic acid from spent V2O5-WO3/TiO2 catalyst
Large amounts of selective catalytic reduction (SCR) denitrification catalysts with poor mechanical property are disposed and difficult to be regenerated, resulting in environmental pollution. For spent SCR denitrification catalyst, the ratio of V4+ /V5+ decreased by about 45% and Fe impurity increased > 10 times, which influenced the recycling of ...
Distinct synergetic effects in the ozone enhanced photocatalytic degradation of phenol and oxalic acid with Fe3+/TiO2 ca...
In this work, phenol and oxalic acid (OA) degradation in an ozone and photocatalysis integrated process was intensively conducted with Fe-3+/TiO2 catalyst. The ferrioxalate complex formed between Fe3+ and oxalate accelerated the removal of OA in the ozonation, photolysis and photocatalytic ozonation process, for its high reactivity with ozone and U...
Preparation of ground calcium carbonate-based TiO2 pigment by a two-step coating method
A two-step coating method for preparing ground calcium carbonate-based TiO2 pigment (GOD) was proposed and studied in this paper. The tetraethoxysilane (TEOS, C8H20O4Si) was selected as Si source. Aqueous ammonia was used as precipitant in the first coating step while titanyl sulfate (TiOSO4 center dot 2H(2)O) was used as Ti source in the second st...
Superior lithium adsorption and required magnetic separation behavior of iron-doped lithium ion-sieves
The recent research on adsorption-based lithium recovery from lithium-containing solutions has been centred on adsorption capacity and separation of lithium ion-sieves powder from solutions. Herein, an effective iron-doped lithium titanium oxide (Fe-doped Li2TiO3) was synthesized by Fe-doping via solid state reactions followed by acid treatment to ...
