Natural Bentonite as a Catalyst/Co-Catalyst Material for the Manufacture of Hydrogen Gas and Oxygen from Water

Introduction

Bentonite, a type of mineral, has been gaining attention in various industrial applications due to its potential as a catalyst and co-catalyst in the process of making hydrogen gas and oxygen from water. Research conducted in Padang Tualang District, Langkat Regency, has produced a type of Na-Bentonite bentonite that has undergone a series of processing processes to improve its performance. This article will discuss the potential of natural bentonite as a catalyst/co-catalyst material for the manufacture of hydrogen gas and oxygen from water.

The Process of Activating Bentonite

The process of activating bentonite begins with saturation of bentonite in a 1 M sodium chloride solution (NaCl) for one day to enrich its Na content. This is followed by activation using sulfuric acid (H2SO4) with a concentration that varies between 0.5 to 2.0 M for 24 hours, before drying. The activated bentonite is then integrated and called using a complex solution of TICl4 with a concentration of 0.82 M and calcined at 350 ° C. The result of this process is the transparted bentonite containing TiO2, which is then analyzed using various methods such as X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Surface Area Analysis (BET), and Electron Microscopy (SEM) scanning.

Analysis of the Results

The results of the analysis showed that the best activation conditions for Na-Bentonite occurred at the concentration of sulfuric acid 1.5 M. To increase the characteristics of porosity, the TiO2 bentonite is then undergoing an ETSA process using a solution (HNO3/ HF/ CH3COOH/ I2) and HF/ H2O/ NH4F solution. This process aims to enlarge the cavity between the silicate layer and increase the surface area of the material. After the heating process at a temperature of 400-500 ° C for one hour, obtained material with a surface area of 92.01 m²/g and pore volume 0.044 cm³/g, which is visualized using SEM.

The Role of Bentonite as a Co-Catalyst

This dietary bentonite functions as a co-catalyst in the water hydrolysis process (H2O) to produce hydrogen and oxygen gas. In the test, the total gas produced from the TiO2 bentonite that had been died reached 78.5% after 4 days, while the not dietary bentonite only produced 60.4% at the same time. These results indicate that natural bentonite that has been processed properly has a higher potential as a catalyst in the reaction of water breakdown into hydrogen and oxygen gas.

Additional Analysis and Explanation

Increased efficiency in the production of hydrogen gas and oxygen using bentonite as a catalyst indicates the great potential of this mineral in the application of renewable energy. The water hydrolysis process is one promising way to produce clean fuel, which can replace the depleted fossil energy source. The use of bentonite, especially the TiO2 bentonite, not only reduces production costs, but also increases the effectiveness of the reaction.

One key factor in the use of bentonite as a catalyst is an increase in surface area and porosity. Material with a larger surface area allows more water molecules to interact with the surface of the catalyst, which accelerates chemical reactions. The analysis shows that appropriate modifications and processing can produce bentonite with excellent characteristics as a co-catalyst.

Conclusion

From this study, it was clear that the use of natural bentonite, especially bentonite from Padang Tualang District, Langkat Regency, not only provided solutions to clean and efficient energy sources, but also opened the way for further research in the development of superior catalyst materials. The use of bentonite as a local raw material for catalyst making provides additional benefits in terms of sustainability and reduction of carbon traces. With its potential, natural bentonite can be an environmentally friendly alternative in the development of clean energy technology and can contribute to solving global energy problems.

Future Research Directions

Further research is needed to explore the potential of natural bentonite as a catalyst/co-catalyst material for the manufacture of hydrogen gas and oxygen from water. This includes investigating the effects of different processing conditions on the properties of bentonite and its performance as a catalyst. Additionally, studies on the scalability and cost-effectiveness of using bentonite as a catalyst material are necessary to make it a viable option for industrial applications.
