Synthesis, characterisation of nanoporous AlSiO4-5 and AlSiO4-12 catalysts, and its green catalytic application of CO2 decomposition

Abstract

Global warming is a trendy term among researchers due to the increase of global temperature which causes severe environmental changes. By melting ice, causing weather extremes like flooding, water shortage and intense storm damage and disrupting the delicate balance of the oceans with increasing of CO 2 level in the atmosphere. In this paper, biodegradable surfactants (SDS and SDBS) are used as a template for the synthesis of solid acid catalysts. The influence of templates in the structural changes is studied by various spectroscopic techniques. The synthesised material is packed in a new U-type catalytic reactor and used for carbon dioxide decomposition reaction. AlSiO 4 -5 and AlSiO 4 -12 decomposed the CO 2 molecules into carbon monoxide, oxygen and carbon. AlSiO 4 -12 decomposed nearly 73% of carbon dioxide at 100°C and AlSiO 4 -5 decomposed 25% of CO 2 at 70°C. Complete decomposition also maximum in AlSiO 4 -12 (31%).

Metal ion effect on pore size reduction in Mesoporous Aluminosilicate in the presence of TETA as a template and its catalytic performance of CO2 decomposition at lower temperature

“…Carbon dioxide was converted to valuable products by Oxygen deficient spinel, [16] Ni‐ferrite [17] and barium calcium iron niobate materials [18] at 300 °C to 700 °C. Carbon dioxide was decomposed by using molecular sieves like Zn‐NaY Zeolite (70 %) [19] AlSiO 4 ‐12 (73 %) [20] and zinc modified Zeolite (23 %) [21] . These catalysts are expensive and needed high temperature, but the conversion also less.…”
