In this research, active carbon-based catalyst synthesis and characterization were investigated for different applications in catalysis. The active carbon-based catalyst was combined with metal oxides to dye methylene blue (MB) removal. Water hyacinth is one of the major problems that facing society and especially in Egypt. One of the implications of industrial activities is environmental pollution. One of the major pollutants is dyes that are used in the production of textiles, paper, and clothes. The waste of those dyes discharged into water supplies without treatment, or ineffective treatment will harmfully impact the environment. In this research, the treatment is implemented using active carbon-based catalysts using embedded nanoparticles. That will lead to a huge increase in the surface area of the adsorbent to increase the adsorbent efficiency. The activated carbon was derived from water hyacinths that grow in the Nile River. Water hyacinth has many good uses as it can absorb heavy metals like lead and dyes. Water hyacinth was converted into activated carbon through carbonization. Different dyes were used with different contact times in fixed conditions.

In this research, active carbon-based catalyst synthesis and characterization were tested for potential catalysts to be used in dye removal of methylene blue (MB). Water hyacinth is one of the major problems that is facing humankind and especially here in Egypt. One of the implications of industrial activities is environmental pollution. Dyes used in the production of textiles, paper, and clothes are one of the major pollutants. The waste of those dyes discharged into water supplies without treatment or with ineffective treatment harmfully impacts the environment. In this research, the treatment is implemented using active carbon-based catalysts using embedded nanoparticles. This leads to a huge increase in the adsorbent's surface area, also increasing the adsorbent efficiency. The activated carbon was derived from water hyacinth that grows near the Nile River. Water hyacinth has many practical uses as it can absorb heavy metals like lead and dyes. Water hyacinth was converted into activated carbon through carbonization. Different dyes were used with different contact times in fixed conditions.

Nanoparticles have proven their dominance in many fields of research in this era. Such dominance resulted from outstanding physical and chemical properties amongst other materials, led to a wide focus from different researchers in various fields to further investigate the role of nanoparticles in various applications from drug delivery systems in medicine to catalysis in chemistry. In this research, active carbon-based catalyst synthesis and characterization were investigated for different applications in catalysis as the catalyst was combined with nickel oxides to be used in dye removal of methylene blue (MB). Water hyacinth is a floating perennial aquatic plant native to tropical and sub-tropical South America. The water hyacinth is one of the fastest-growing plants; it reproduces by way of runners or stolon. Each one can produce thousands of seeds each year, which can survive for more than 28 years. It has been considered as a water purifier and a solution to green water issues. Water hyacinth is used in perfume and cologne products, as well as organic fertilizer. It also absorbs lead, mercury, and carcinogens when used for remediation purposes. As it has amazing biomass, it can be used to produce fuels. Activated carbon, also known as activated charcoal, is a carbonaceous, highly porous absorptive medium of a complex structure composed of carbon atoms. It is used in gas purification, gold purification, metal extraction, medicine, sewage treatment, air filters, in gas masks used to purify liquids in many applications, including drinking water and odor removal. This research aims to prepare active carbon derived from water hyacinth and embedded with nickel nanoparticles. The water hyacinth will be converted into active carbon and used as a support for nickel nanoparticles. A comparison between active carbon derived from water hyacinth and activated nickel nanoparticles will be conducted to test the rate of absorbance based on the effect of time, concentration, and kinetic energy.

The dates about effect of temperature of carbonizats obtaining from pine bark on evolution of a porous structure and sorption properties of the activated carbons, synthesized by the method of thermoalkaline activation in the presence of КОН were presented. It was determined, that for preparation of activated carbons with the greatest specific surface (1421 and 1655 m2/g) and micropores volume (0.58 и 0.71 sm3/g) pine bark carbonizats reasonable to obtain at temperature 300 and 400 °С correspondingly. The correlation of a iodine sorption with volume of micropores width 0.73–3.0 nm (R2=0.964) and a methylene blue sorption with volume of micropores width 0.84–2.0 nm (R2=0.995), which present in the activated carbons structure, was established. It was shown, that low capacity of the activated carbons to vitamin B12 sorption determine by low mesopores volume with width ≥5 nm (no more than 0.0014 sm3/g). It was shown, that the activated carbon based on carbonizat obtained at 400 °С demonstrates a maximal sorption capacity to a iodine and a methylene blue (1.57 g/g и 697.1 mg/g correspondingly), that in 1.4 and 2.7 times exceeds the dates of an industrial activated carbon for medical purposes.

This study aims to determine the effect of variation of activation temperature of activated carbon from sugar palm bunches of chemically activatied with the activation agent of potassium silicate (K2SiO3) on the adsorption capacity of iodine and methylene blue. Activated carbon from bunches of sugar palmacquired in four steps: preparationsteps, carbonizationstepsusing the pyrolysis reactor with temperature of 300 oC - 400 oC for 8 hours and chemical activation using of potassium silicate (K2SiO3) activator in weight ratio of 2: 1 and physical activation using the electric furnace for 30 minutes with temperature variation of600 oC, 650 oC, 700 oC, 750 oC and 800 oC. The iodine and methyleneblue adsorption testedby Titrimetric method and Spectrophotometry methodrespectively. The results of the adsorption of iodine and methylene blue activated carbon from sugar palm bunches increased from 240.55 mg/g and 63.14 mg/g at a temperature of 600 oC to achieve the highest adsorption capacity of 325.80 mg/g and 73.59 mg/g at temperature of 700 oC and decreased by 257.54 mg/g and 52.03 mg/g at a temperature of 800 oCrespectively.However, it does not meet to Indonesia standard (Standard Nasional Indonesia/SNI), which is 750 mg/g and 120 mg/g respectively.
