Ultrasonic preparation of mesoporous silica using pyridinium ionic liquid [PDF]
, 2016 Mesoporous silica matrices have been prepared via classic acid catalyzed and sono-catalyzed sol-gel routes. Tetramethoxysilan (TMOS) and methyl-trimethoxysilane (MTMS) were used as silica precursors, and N-butyl-3-methylpyridinium tetrafluoroborate ...

Angewandte Chemie International Edition, EarlyView.A core–shell strategy is presented to overcome the high first‐cycle losses of non‐graphitic hard carbon anodes. Activated carbon is sealed by gas‐phase carbon deposition to create semi‐permeable shells that spatially separate SEI formation from Na storage in a retained nanoporous core. The resulting anode delivers 400 ± 24 mAh g−1 with an ICE of 82 ± 2%

Synthesis of highly porous alumina-based materials [PDF]
, 2013 γ-Alumina-based materials with high porous volume, tunable pore size, were synthesized by the addition of both PEO/PPO/PEO triblock copolymers (Pluronics® F127 and P123) and metal nitrates (Al3+, Mn2+, Cu2+) in a boehmite (AlOOH) nanoparticle hydrosol ...

Batteries &Supercaps, Volume 8, Issue 3, March 2025.This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.
