TiO₂/porous carbon as a new nanocomposite and catalyst for the preparation of 4H-pyrimido[2,1-b]benzimidazoles

Abstract

A nano TiO2/porous carbon nanocomposite (TiO2/PCN) was designed by the pyrolysis of peanut shells as bio waste with nano titanium dioxide and was successfully tested as a catalyst for the preparation of some 4H-pyrimido[2,1-b]benzimidazoles.
