Zinc oxide nanoflakes were synthesized using the wet precipitation method from aqueous solutions of zinc nitrate and sodium hydroxide. The obtained materials were characterized by means of X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and nitrogen adsorption–desorption methods. The presence of sodium laur...

The incorporation of ultrafine SnO2 particles inside N-doped ordered mesoporous carbon (N-CMK3) is suggested as a method to prepare an ultrastable anode material for Li-ion batteries. Sn nanoparticles formed by chemical reduction of SnCl4 inside N-CMK3 pores are spontaneously reoxidised by dissolved oxygen, resulting in the formation of ultrafine S...

In this study, Fe 3 O 4 nanoparticles used as an adsorbent for the removal of toxic gases were successfully synthesized via the facile coprecipitation method. The Fe 3 O 4 nanoparticles displayed a well-defined morphology with the size of ∼10 nm and a porous structure with a specific area of 115.90 m ² /g and a wide range of pore sizes. These nanop...

In this study, we introduce a facile and simple synthesis of Sb@C nanosponges by the citrate sol-gel method, accompanied with conventional carbonization in an inert gas. The synthesized Sb@C nanosponges are comprised of Sb nanoparticles encapsulated by a carbon shell, interconnected to form a highly porous three-dimensional structure. The carbon co...

In this study, a self-encapsulated Sb-C nanocomposite as an anode material for sodium-ion batteries (SIBs) was successfully synthesised using an SbCl3-citrate complex precursor, followed by a drying and calcination process in an inert N2 atmosphere. When the molar ratio of SbCl3 to citric acid was varied from 1:1 to 1:4, the Sb-C nanocomposite with...

Porous Si is considered a potential anode material for next-generation Li-ion batteries (LIBs) because of its high specific capacity, low lithiation/delithiation potential, low cost, and environmental friendliness. In this work, we introduce a simplified Mg-thermal-reduction method for the production of mass-scalable coral-like bulk-Si powders with...

We propose a simple method for direct synthesis of a Si@SiC composite derived from a SiO2@C precursor via a Mg thermal reduction method as an anode material for Li-ion batteries. Owing to the extremely high exothermic reaction between SiO2 and Mg, along with the presence of carbon, SiC can be spontaneously produced with the formation of Si. The syn...

Li–ion batteries (LIBs) have been studied extensively in the past decades and become one of the most successful energy storage devices, which have rapidly penetrated into our lives. However, due to the limited supply and uneven global distribution of Li resources, the cost of LIBs may increase severely in the near future. Therefore, it is vital to...
