Opal synthesis
WebIn this work, we present a modification of the sol-gel based, Stöber, Fink and Bohn’s (SBF) procedure for the preparation of nanometric spheres of silica with a monomodal distribution of size and controlled diameter. In the SBF method, tetraethyl orthosilicate (TEOS) is used as a precursor molecule and hydrolysis and condensation reactions to form chains and … Web19 de jan. de 2024 · Poor conductivity and sluggish Na+ diffusion kinetic are two major drawbacks for practical application of sodium super-ionic conductor (NASICON) in sodium-ion batteries. In this work, we report a simple approach to synthesize quasi-inverse opal structural NASICON/N-doped carbon for the first time by a delicate one-pot solution …
