PROBLEM STATEMENT

The serious problems to use hydrogen as a fuel is hydrogen storage and transportation due to the high reactivity of hydrogen ,so to stored

this we are making CNT’s by using of MCM-41 catalyst .To use hydrogen as a future fuel.

INTRODUCTION

Potentially, Hydrogen can be used as a fuel and can act as a substitute for petroleum-based fuels in later stages. The major reason for it is:

•Environmental friendly as the resultant product we obtain is water only by Combustion of H fuel.

But unfortunately Hydrogen fuel is not being commercially used as the storage of Hydrogen is a big concern due to requirement of cryogenic environment and highly insulated storage tanks.

WHAT IS MCM 41 ?

•Mobil Composition of Matter No. 41•Mesoporous material with a hierarchical structure from a family of silicates.•Used as catalysts for various chemical reactions, as a support for drug delivery system and as adsorbent in waste water treatment.

OBJECTIVE

To achieve high purity and high performance of the catalyst.

•Synthesis of Fe-Co MCM-41 Catalyst with varying the molar ratios of Fe,Co with respect to Si.

•Characterization of synthesized catalyst by XRD, FT-IR.

•Optimization of catalyst conditions (purity and structure) after analysing its properties

8

Measure the average spacing between layers or rows of atoms.

Determine the orientation of a single crystal or grain.

Find the crystal structure of an unknown material. Measure the size, shape and internal stress of small crystalline regions.

Why XRD?

FT-IR RESULT(Fe-Co)

17

 •A broad band around 3442.92 cm-1 is due to OH stretching of water. The broad band between 1300 and 1000 cm-1 (1098.89 cm-1) is due to internal and external asymmetric Si-O-Si stretching modes. The band at 805.07 cm-1 is assigned to symmetric stretching of Si-O-Si.

FTIR ANALYSIS

18

From the low angle XRD pattern on comparing with the standard result the peak came between 2 & 3 degree but the peak was very low intensity for Fe MCM-41 which suggest that catalyst was not formed.From high angle XRD pattern another peak was found which correspond to Fe2O3.

From FT-IR before and after calcination the changes in peak which suggest that calcination is complete.We also found that improper mixing of the gel formed, led us to the deviation from MCM-41 Structure.

Result and Analysis

19

• Synthesize Fe-Co of different ratios with respect to Si by varying other parameters such as crystallization time.

• To recheck the procedure steps involved to improve the yield and prevent impurities.

• To synthesize MCM-41 catalyst for CNT preparation.

• Analyze the results for changes and evaluate for proficiency.
