Carbon capture from large sources and ambient air is one of the most promising strategies to curb the deleterious effect of greenhouse gases. Among different technologies, CO2 adsorption has drawn widespread attention mostly because of its low energy

Three classes of organosilicas (DMO, OMOs and PMOs) containing immobilized multi-hydroxyl bis-(quaternary ammonium) iodide salts were prepared and tested in the cycloaddition of CO2 and epoxides. Owing to its higher surface area, pore volume and opti

Tumbling chemical vapour deposition (T-CVD) is presented as a novel methodology for the gas phase grafting (GPG) of a variety of alkoxy- and chloro-silanes on mesoporous silica. Compared to conventional solution grafting techniques, this method is su

N,N,N-tributyl-N-propylammonium iodide-functionalized mesoporous silicas (SBA-15 and a silica gel) proved to be efficient, robust and reusable catalysts for the solvent-free synthesis of cyclic carbonates (CCs) from epoxides and CO2. The reusability

We report for the first time, a novel one-pot protocol for the synthesis of large-pore AlMCM-41 aluminosilica materials (i.e. LP-AlMCM-41(y), where y = Si/Al ratio). Assisted by a pore-expansion agent, i.e. N,N-dimethylhexadecylamine (DMHA) and the s
