Citrate complexation microwave-assisted synthesis of Ce_0.8Zr_0.2O₂nanocatalyst over Al₂O₃used in CO oxidation for hydrogen purification: influence of composite loading and synthesis method

Abstract

Nanostructured Ce0.8Zr0.2O2/Al2O3 composite catalyst was synthesized by modified citrate complexation method. Utilizing microwave combustion endowed the sample with more uniform and homogenous pattern leading to better CO oxidation.

Supported nanocatalysts: recent developments in microwave synthesis for application in heterogeneous catalysis

“…Fair number of attempts have also been made to prepare supported simple metal oxide (CoO x , Co 3 O 4 , NiO, Fe 3 O 4 , SnO 2 , CeO 2 , TiO 2 ) nanocatalysts for application in petrochemical industry. 75,[160][161][162][163][164][165][166] In order to improve the catalytic activity as well as versatility in application potential of simple metal or metal oxide nanocatalysts, investigations on supported bimetal, [171][172][173][174][175][177][178][179][180][181][182][183][184][185][186][187] mixed metal oxide [188][189][190][191][192][193]196,197 and ternary metal 198,199 nanocatalysts are also available. MW assisted synthesis has been claimed to be economically viable short green method to produce supported nanocatalyst.…”

Influence of Fuel to Oxidizer Ratio on Microwave-Assisted Combustion Preparation of Nanostructured KOH/Ca12Al14O33 Catalyst Used in Efficient Biodiesel Production

“…Microwave irradiation as a novel technology has been widely considered in chemical reactions (Ajamein and Haghighi, 2016;Rezaee and Haghighi, 2016) and it has been extensively studied in the field of biodiesel production in order to reduce production and separation times. Refaat et al reported that, in addition to the reduction of the transesterification reaction time (from 75 to 4 min), the separation time was also reduced (from 60 to 3 min) (Refaat and El Sheltawy, 2008).…”
