Catalysis of oxidation of carbon monoxide on supported gold nanoparticle

Self-sustained combustion of carbon monoxide promoted by the Cu-Ce/ZSM-5 catalyst in CO/O 2 /N 2 atmosphere

“…Moreover, the band in the spectra of non-coordinated carbonates is observed at 1430 cm −1 . At higher wavenumbers, the bands at 2112 and 2172 cm −1 are related to the C-O stretching mode of Cu n+ -CO complexes [28,29]. …”

Effect of hydrothermal reaction time and calcination temperature on properties of Au@CeO2 core–shell catalyst for CO oxidation at low temperature

“…Since Haruta [6] first reported that Au/TiO 2 nanoparticles have outstanding catalytic activity for CO oxidation at low temperature, numerous studies on Au/oxide [7,8] catalysts for CO abatement have been reported. Up to now, Au/oxide catalysts have been recognized as a general catalyst for CO oxidation and widely used in hydrogen purification in fuel cell technology [9,10], water-gas shift reactions, and CO elimination in the exhausted gas from automobile [11,12].…”

Ultra-fast catalytic reduction of dyes by ionic liquid recoverable and reusable mefenamic acid derived gold nanoparticles

“…Interest in gold based catalysts is increasing due to their fascinating properties, green nature and ability to catalyze selective reactions at low temperatures [2,3]. Application of AuNps as catalysts reveals that their catalytic potential is highly dependant upon variation in size [4][5][6][7]. Despite size, one of the big secrets for best catalytic results lies in strategic control of the shape of Nps in order to increase their unsaturated free surface sites [8][9][10].…”

“…Despite size, one of the big secrets for best catalytic results lies in strategic control of the shape of Nps in order to increase their unsaturated free surface sites [8][9][10]. The application of Nps as heterogeneous [2,4] or homogeneous [2,11] catalysts is generally needed in various studies and preferred by merit. The active sites in heterogeneous catalyst are protected from full reactivity due to strong interaction with capping agent or surface while homogenous catalyst shows maximum reactivity due to better access of sites [12][13][14].…”
