The production of cobalt-60 is critical to healthcare and, with demand soaring, the challenge is to expand supply, writes Martin Comben from the International Irradiation Association.
2018年,中国地质大学材料与化学学院材料系芦露华教授团队在催化领域国际权威期刊《Applied Catalysis B: Environmental》 (应用催化B,2016年IF=9.446)上在线发表题为“Boosting visible light photocatalytic hydrogen evolution of graphitic carbon nitride via enhan...
By means of direct nucleation and growth on the surface of graphene and element doping of cobalt oxide(Co3O4) nano-particles, manganese–cobalt oxide/graphene hybrids (MnCo2O4–GNS) were synthesized tor...
A series of alumina supported cobalt oxide based catalysts doped with noble metals such as ruthenium and platinum were prepared by wet impregnation method. The variables studied were difference ratio ...
A straightforward and general method has been developed for the synthesis of C5-unsubstitiuted 1,4-dihydropyridines by a reaction using dimedone, acetophenone, aromatic aldehydes, and ammonium acetate...
The catalysts of Co/Zr-SiO2 were prepared by precipitation and the promoter of Pt was supported by impregnation. The reducibility of the cobalt oxide and the other physicochemical properties of the ca...
A process is developed to recover nano-sized cobalt from cemented carbide scrap (WC-Co) by nitric acid leaching and nally obtaining a nano-sized spherical pure cobalt powder by ultrasonic spray pyrol...

Gold-Cobalt Electrodeposits.
Cobalt catalysts supported on amorphous SiO2 and ordered mesoporous silica (MCM-41) were preparedby incipient wetness impregnation. Gold was addedby consecutive impregnation or by co-impregnation.The ...
The differences between MoS2, CoMoS and NiMoS HDS catalysts supported on γ-alumina and high SSA titania are investigated based on the results of [35S]DBT HDS experiments. Previous studies of MoS2 and ...
Newly developed CoMo titania catalysts for ultra-deep hydrodesulfurization (HDS) of diesel oil have higher activities for both HDS and hydrodenitrogenation (HDN), whereas the chemical hydrogen consum...
The effect of cobalt addition on Mo/Al2O3 hydrodesulfurization catalyst was investigated by 129Xe NMR. Both the amount of adsorbed xenon and the peak width of 129Xe NMR were almost constant at variou...
Characterization of nickel and cobalt catalysts supported on oxidized diamond (O-dia) in the partial oxidation of methane to synthesis gas was carried out by X-ray photoelectron spectroscopy (XPS) an...
The aim of this work was to determine physical and chemical properties of cobalt aluminate (CoAl2O4) modifiers produced by different companies and the influence of different types of modifiers on the...
