“…Hence, a potential and straightforward solution is to integrate SiO x with carbon because the benefits of carbon with excellent mechanical elasticity and intrinsic conductivity are considered to increase the electrical conductivity of the composite as well as accommodate volume expansion during charge−discharge processes to maintain a stable electrochemical performance. 27 Izawa et al 28 reported the preparation of a SiO x /C nanocomposite by using the simultaneous hydrolysis−condensation of tetraethyl orthosilicate (TEOS) and the polymerization of 3-aminophenol. In this case, the hydrolysis of TEOS was slower than 3-aminophenol polymerization; therefore, SiO x nanoparticles were dispersed on the polymer surface, and the carbon layer did not perfectly coat SiO x .…”

Core–shell particles are desirable for many applications, but the precise design and control of their structure remains a great challenge. In this work, we developed a strategy to fabricate carbon-coated SiO x (SiO x @C) core–shell particles via a sol–gel method using the simultaneous hydrolysis–condensation of tetramethyl orthosilicate (TMOS), the polymerization of 3-aminophenol and formaldehyde in the presence of ammonia as a basic catalyst, and cetyltrimethylammonium bromide (CTAB) as a cationic surfactant in the mixed solution of water and methanol followed by the carbonization process. Results from this study provide new insight into the design of core–shell particles by using TMOS as an effective silica precursor for the first time with a well-controlled reaction rate and spherical morphology. To obtain an in-depth understanding of the formation of core–shell structure, a possible mechanism is also proposed in this article. When tested as an anode material for lithium ion batteries (LIBs), the obtained SiO x @C particles delivered a reversible capacity of 509.2 mAh g–1 at a current density of 100 mA g–1. This electrochemical performance is significantly better than those of similar composites without the core–shell structure. The capacity retention after 100 cycles was approximately 80%. These results suggest great promise for the proposed SiO x @C particles with core–shell structure, which may have potential applications in the improvement of various energy-storage materials.

“…The main drawback of such substitution, the lower capacity delivered in batteries of SiO x in comparison with Si, can be overtaken adding a conductive layer like carbon or graphite. Taking this into account, Ogi et al developed two microwave-assisted procedures to easily prepare carbon-SiO x particles for Li-ion battery anodes [ 73 , 74 ] ( Scheme 4 ).…”

Microwaves are a source of energy of great interest for chemical synthesis. Among nanomaterials, few are as versatile as silica—it forms mesoporous materials and nanoparticles, it can be incorporated as shells or loaded in composites, it can also be functionalized. Despite the relevant properties of silica, and the advantages of the use of microwave as energy source, its use in silica-based materials is not frequent. We report herein a compilation of the research results published in the last 10 years of microwave assisted synthesis of silica based materials. This review includes examples of mesoporous materials for waste removal, catalysis, drug release, and gas adsorption applications, together with examples based in the optimization of the synthesis conditions. In the case of non-porous materials, examples of analytical applications, coating of metallic nanoparticles, and SiOx-C materials have been collected.
