Copper Containing SBA-15 Prepared Through pH Modification Methods and its Catalytic Activity for N2O Decomposition

Copper-substituted SBA-15 (Cu/SBA-15) mesoporous materials were directly synthesized under acidic conditions by a pH modification method using hexamethylenetetramine (HMTA) as an internal pH-modifier. The synthesized material has been characterised by XRD, SEM-EDX, TEM and FTIR. The results showed t...
