Synthesis of carbon tubes with mesoporous wall structure using designed silica tubes as templates†
Abstract
Hollow silica tubes with mesoporous wall structure were synthesized through the sol–gel reactions of tetraethoxysilane and n-octadecyltrimethoxysilane (TEOS/C18-TMS) on the surface of ammonium dl-tartrate crystals. Novel hollow carbon tubes with mesoporous walls and rectangular-shaped channels were fabricated using the silica tubes as templates.
