Figure3. Methods of Zeolite Synthesis 3.1Conventional Method: Conventional zeolite synthesis involves the various me thods like hydrothermal, One Step, Direct, Exchanging, Seeding and aging me thod 3.1.1Hydrothermal method: Zeolite was synthesized at high tempe rature and pressure using autoclave. 3.1.2One step Method: Materials were fused with sodium hydroxide in muffle furnace . 3.1.3Direct Me thod: Two raw materials directly mixed with different condition to synthesize **zeolite . 3.1.4Exchanging Method: Sodium type zeolite (Na-Zeolite) mixed with Metal salt i.e. Cu, Fe, and Ni, etc. and stirred at room temperature. 3.1.5Seeding and aging Me thod: It is use to produce highly pure zeolite with the absence of othe r impuritie s. 3.2Green method for Synthesis of zeolite: In current trends, the main problem in zeolite researche r is the availability and cost of raw materials and conventional synthetic method. In materials specifically in alumina and silica source. Alumina sources are Dross, re dmud, etc. by Green me thod like Microwave and ultrasonic method 3.2.1Microwave method: Microwave irradiation activates the mate rials and synthe sized the zeolite . This method is used to reduce the time as well as increase the yie ld of zeolite . 3.2.2Ultrasonic method: This method is use to remove curing step (long heating).ultrasonic sound wave irradiate with materials used for synthesis of zeolite .

A versatile synthetic method was applied for the preparation of Sn containing bimetallic catalysts. The syn- thesis was performed by simply mixing the super hydride [LiBIJC2H5)3H], with a metal (Ru, Rh or Ir) salt and an organotin complex in tetrahydrofuran solvent without using any surfactant. This leads to the formation of monodispersed M–Sn (M =...
Iron‐catalyzed C−H activation has recently emerged as an increasingly powerful synthetic method for the step‐ and atom‐ economical direct C−H functionalizations of otherwise inert C−H bonds. Iron's low‐cost and toxicity along with its catalytic versatility have encouraged the scientific community to elect this metal for the development of new C−H a...
The development of cost-efficient electrocatalysts for urea oxidation reaction (UOR) is a challenge due to the slow kinetics. In this work, we demonstrated a one-pot hydrothermal synthetic method to fabricate CeO2 modified Ni-MOF nanosheets. When evaluted as UOR catalysts, the 3% CeO2/Ni-MOF possesses outstanding catalytic activity, achieving a cur...
A selective synthesis of hydrazoarene from nitroarene and its application are reported. Using polystyrene (PS) resins as solid supports for Au nanoparticles (AuNPs), polystyrene-supported Au nanoparticles ([email protected]) were synthesized and characterized. In the presence of [email protected] (1.0 mol %) as a catalyst, nitroarenes afforded corr...
Modern three-way catalysts in catalytic converters, used to control air pollution from automobiles, are still expensive and ineffective at light-off temperatures. Bimetallic nanoparticles were deemed to be the solution to this challenge. However, their superiority remains a myth due to the lack of uniformity in their synthetical methods performed b...
