Scheelite nanostructures Ca1−2x(Eu,Na)2xWO4 (0 < x ≤ 0.135) were prepared from 5 nm Ca0.968(Eu,Na)0.032WO4 by hydrothermal treatment. The preparation of at room temperature and subsequent treatment allow control over chemical compositions particle size CaWO4-based red phosphors that has not yet possible when using traditional methods. By careful structural electronic characterization, it is shown simultaneous substitutions Eu3+ Na+ Ca2+ sites this methodology, which allows one to vary the...
Increasing long-term photostability of BiVO4 photoelectrode is an important issue for solar water splitting. The NiOOH oxygen evolution catalyst (OEC) has fast oxidation kinetics compared to the FeOOH OEC. However, it generally shows a lower photoresponse and poor stability because more substantial interface recombination at NiOOH/BiVO4 junction. Herein, we utilize plasma etching approach reduce both interface/surface NiOOH/electrolyte junctions. Further, adding Fe2+ into borate buffer...
Abstract This work reports on the construction of a Bi 24 O 31 Cl 10 /BiOCl heterojunction via simple thermal annealing method. The X-ray diffraction (XRD) results indicated that phase transformation from BiOCl to could be realized during process. high-resolution transmission electron microscopy (HRTEM) images, photoelectron spectroscopy (XPS) binding energy shifts, Raman spectra and Fouier transform infrared (FT-IR) confirmed formation heterojunction. obtained photocatalyst showed excellent...
In situ catalyst regeneration of NiFe-based oxygen evolution (OEC) has been recognized as one the best approaches for photocorrosion inhibition on water splitting photoelectrodes. However, it generally suffers from laborious multistep procedures to obtain a controllable film. Herein, we use an electron density modulation synthesize stable NiFeY layered double hydroxide (LDH) OEC and then deposit this BiVO4 photoanodes. The incorporation Y modifies chemical environment Ni reduces bandgap NiFe...
This work reports on the preparation of a noble-metal-free and highly active catalyst that proved to be an efficient green reductant with renewable capacity. Nitridation silent Ta1.1O1.05 substrate led formation series TaOxNy hollow nanocrystals exhibited outstanding activity toward catalytic reduction nitrobenzenes under ambient conditions. ESR XPS results indicated defective nitrogen species oxygen vacancies at surfaces may play synergetic roles in nitrobenzenes. The underlying mechanism...
In this work, we report on the microwave-assisted hydrothermal synthesis of Sn2+-doped ZnWO4 nanocrystals with controlled particle sizes and lattice structures for tunable optical photocatalytic properties. The samples were carefully characterized by X-ray diffraction, transmission electron microscopy, inductive coupled plasma emission spectroscopy, UV–vis diffuse reflectance Barrett–Emmett–Teller technique. effects Sn2+ doping in crystal structure, electronic photodegradation methylene...

Abstract A novel direct Z‐scheme CuBi 2 O 4 /BiOBr heterostructural photocatalyst was developed aiming to modulate the adsorption ability and photocatalytic degradation performance toward antibiotics. Tetracycline as model antibiotics found show pH value temperature dependent capacity over /BiOBr. The process fitted Pseudo‐second‐order Elovich kinetic models isotherm followed Freundich model. Junction of BiOBr can surface feature interfacial interactions, leading charge kinetics for improved...
This work reports on a combinational methodology to CaWO4 nanocrystals of controllable particle sizes for comprehension size dependences physical properties. Citric acid as capping molecule restricted the growth and gave small 3.6 nm at room temperature pH 8, while large or absence were always observed when value was higher lower than 8. Hydrothermal treatments over high temperatures led systematic increase in sizes. X-ray diffraction, infrared spectroscopy, transmission electron microscopy,...
This work initiates an investigation on the creation of room-temperature ferromagnetism in diamagnetic solid via a nonmagnetic doping. CeO(2) is taken as prototype compound. A series Ce(1-x)Ca(x)O(2-delta) solutions with x = 0-0.25 were prepared by solution combustion method using L-glutamic acid fuel. Sample characterization indicates that all as-prepared samples crystallized pure face-centered cubic fluorite structure crystallite sizes smaller than 10 nm. On increasing dopant content, size...
Highly crystalline SnO2 nanocrystals with and without Zn2+ doping were directly prepared by a solvothermal method. By systematic characterizations using x-ray diffraction, transmission electron microscopy, infrared spectra, UV–vis it is demonstrated that all samples crystallized in single phase of rutile structure, upon particle sizes closer to the exciton Bohr radius (2.7 nm) achieved, while size nanoparticles was as large about 12 nm doping. The smaller for doped had led lattice expansion,...
