The mesoporous materials have variety of applications in several field particularly it has a main role in Catalysis, Petrochemical industries and Adsorption. Normally the porous material has well ordered 3Dimensional structure, huge surface area, high thermal stability and active acid sites. The properties of these materials can be varied because it is mostly depends on its template, synthesis method and isomorphous substitution of metal ions. There are two major mesoporous materials which are aluminosilicate and aluminophosphate. In this present investigation AlCl3 and FeCl3 are used in equal amount for the synthesis of mesoporous material. The synthesized material is characterized by FT-IR, XRD, TGA, BET, EDAX and TPD. Morphological images were studied by SEM. These characterization techniques confirm the formation of mesoporous molecular sieves.

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%).

: Organic dyes are used for dyeing cotton, plastic, wool etc. The dye manufacturing and dyeing industries are releasing unused organic dyes as an effluent. Every year five billion tons of waste organic dyes are pumped into river, ocean and other water bodies. The dyes are stable and non -bio degradable. Many methods are adopted to remove the dyes from dye effluent. But, these methods are creating another environmental issue and also dye removal is not 100% successful. Identification of Human, animal and fish poisoning organic dyes are essential, to control their toxicity. In this present investigation, sardine fish is selected to identify the fish poisoning and non -poisoning organic dyes through adsorption method. The experimental conditions like contact time, temperature, dye concentration, fish powder dosage are optimized to find out the maximum toxic effect of organic dyes on fish. The poisoning effect has been evaluated by adsorption thermodynamics, kinetics and isotherms.
