and nano-sized pore materials like Si-MCM-41, Ti-MCM-41 and Al-MCM-41Analogues were successfully synthesised using different methods: precipitation, sol-gel, micro-emulsion and hydrothermal treatment. These obtained nano-structured materials were characterised by using different physico-chemical methods: FE-SEM, TEM, XRD, IR, UV-vis and nitrogen adsorption/desorption (BET). These materials were examined to investigate adsorptive and catalytic properties of the materials. Nano TiO

exhibited highly photocatalytic activity in the degradation of methyl red (MR). Pure silica form MCM-41 (Si-MCM-41Analogue) was a selective absorbent for VOCs (m-xylene) removal. Ti substituted MCM-41Analogue exhibited highly photocatalytic activity in the degradation of red phenol (RP) while Al substituted MCM-41Analogue showed high catalytic cracking of petroleum residue (Bach Ho oil field – Vietnam). The obtained results are discussed and rationalised.
