Abstract
Carbon monoxide (CO) is the most harmful pollutant in the air, causing environmental issues and adversely affecting humans and the vegetation and then raises global warming indirectly. CO oxidation is one of the most effective methods of reducing CO by converting it into carbon dioxide (CO2) using a suitable catalytic system, due to its simplicity and great value for pollution control. The CO oxidation reaction has been widely studied in various applications, including proton-exchange membrane fuel cell technology and catalytic converters. CO oxidation has also been of great academic interest over the last few decades as a model reaction. Many review studies have been produced on catalysts development for CO oxidation, emphasizing noble metal catalysts, the configuration of catalysts, process parameter influence, and the deactivation of catalysts. Nevertheless, there is still some gap in a state of the art knowledge devoted exclusively to synergistic interactions between catalytic activity and physicochemical properties. In an effort to fill this gap, this analysis updates and clarifies innovations for various latest developed catalytic CO oxidation systems with contemporary evaluation and the synergistic relationship between oxygen vacancies, strong metal-support interaction, particle size, metal dispersion, chemical composition acidity/basicity, reducibility, porosity, and surface area. This review study is useful for environmentalists, scientists, and experts working on mitigating the harmful effects of CO on both academic and commercial levels in the research and development sectors.

Abstract
An efficient 'structure-property' catalyst Ag-CuO/SBA-15 for aerobic epoxidation of olefins was designed and prepared via a simple grinding method, which provided a dynamic assembly driving force to push the precursors into the channels step by step. Partial melting on the precursor particles surface is necessary for synthesizing the Ag-CuO/SBA-15 catalysts. During the thermal grinding process, the partial melting Cu(NO3)2 first adhered on AgNO3 particles surface because the N of AgNO3 possess stronger interaction with Cu(NO3)2 than OH- of SBA-15, then the mixture of melting precursors on AgNO3 particles surface were sucked into the channels of SBA-15 step by step. Finally, high dispersion of both Ag and CuO nanoparticles were formed in the SBA-15 channels after calcination. The interaction between Ag and CuO, which was characterized by high-resolution transmission electron microscopy, UV-vis and x-ray powder diffraction, enhances the catalytic activity of the catalysts, giving high conversion and selectivity to the epoxides. The reaction mechanism is as follows, the solvent xylene molecule was first oxidized on the Ag surface to form methyl-benzaldehyde (R1), and then moved to the CuO surface to form the peroxidic radical (R2), the peroxidic radical attacked the trans-stilbene C=C bonds on the CuO surface to obtain the epoxides. This synergistic effect shows high activity toward the epoxidation of trans-stilbene.

Abstract
In present study, the NO oxidation on Ni-carbon nanocage and Ni-boron nitride nanocage surfaces was investigated. The Ni-C60 and Ni-B30N30 catalysts can oxidize the NO molecule by Langmuir-Hinshelwood (LH) and Eley-Rideal (ER) mechanisms. In this study, the NO molecule was joined to Ni atom of the Ni-surface-O2* and Ni-surface-O* to generate the intermediates with low barrier energies. It can be concluded that the cis-Ni-surface-ONOO* complex in the ER pathway is more stable than four-elements-ring complex in LH pathway ca 0.06 and 0.08 eV, respectively. In the LH pathway, the studied catalysts were deactivated by irreversible absorption of NO2 molecules in Ni atoms of Ni-C60 and Ni-B30N30. In contrast, in the ER pathway two NO2 molecules were released in the normal temperature. In this study, the abilities of the Ni-C60 and Ni-B30N30 to oxidation of NO molecule was demonstrated. Finally, the systematic scheme to design of metal-doped nano-catalysts to oxidation of toxic gases was proposed.

Abstract
Improvement of new nanophotocatalysts enable to decompose the pharmaceutical pollutants with the aid of solar energy is of particular importance. In this research, the ability of SnTe photocatalyst for degradation of warfarin was enhanced and the separation difficulties of the used photocatalyst, from solutions was removed by immobilization of the photocatalyst on a suitable porous support. A novel nano-sized photocatalyst was prepared by coupling of SnTe on the surface of SBA-15 support. Characterization of the synthesized photocatalyst (SnTe@SBA-15) was performed by different methods including XRD, TEM, TGA, FT-IR, EDS and BET techniques. The map of constituent elements was also prepared. The results indicated that the activity of SnTe photocatalyst was significantly enhanced after immobilization on the support and lower catalyst dose was needed. The visible light irradiation was more effective than UV irradiation. The degradation process was kinetically fast, and the equilibrium was established within 10 min. Separation of the synthesized photocatalyst from the solution was much easier than the bulk SnTe. The regenerated photocatalyst retained more than 90% of its initial efficiency.

Abstract
In this work, a simple but powerful method for controlling the size and surface morphology of AgAu nanodendrites is presented. Control of the number of Ag nanoparticle seeds is found to provide a fast and effective route by which to manipulate the size and morphology of nanoparticles produced via a combined galvanic replacement and reduction reaction. A lower number of Ag nanoparticle seeds leads to larger nanodendrites with the particles' outer diameter being tunable in the range of 45-148 nm. The size and surface morphology of the nanodendrites was found to directly affect their catalytic activity. Specifically, we report on the activity of these AgAu nanodendrites in catalyzing the gas-phase oxidation of benzene, toluene and o-xylene, which is an important reaction for the removal of these toxic compounds from fuels and for environmental remediation. All produced nanodendrite particles were found to be catalytically active, even at low temperatures and low metal loadings. Surprisingly, the largest nanodendrites provided the greatest percent conversion efficiencies.
