IRON OXIDE SUPPORTED RHODIUM CATALYST FOR NITROARENE REDUCTION
A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe.sub.3O.sub.4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.
COMPOSITIONS OF OLIGOANILINES AND METHODS OF MAKING AND USING
Compositions of oligoanilines with higher purity, methods of making and using thereof, are provided. The compositions are produced in large scale with larger yield using simple purification techniques such as washing. Methods have been developed that allow large scale synthesis of oligoaniline compounds with the following benefits: (i) higher purity; (ii) larger yield of oligoaniline compounds; (iii) simple purification that does not require complicated techniques such as liquid chromatograph; (iv) lower cost; and (v) full characterization. The highly pure oligoaniline compositions can be used as reducing or oxidizing agent in a redox reaction. The oligoaniline compositions have colors and can be used as dyes, i.e. redox active dyes in a redox reaction, as intermediates for the development of conductive elastomers, or as catalysts.

Organophosphorus degrading enzyme based multifunctional catalyst and preparation method and use thereof
The present disclosure provides a method for preparing an organophosphorus degrading enzyme based multifunctional catalyst and an organophosphorus degrading enzyme based multifunctional catalyst and use thereof. In the present disclosure, the preparation method includes: directly adding a composite yolk-shell-structured nanomaterial into a crude enzyme solution of organophosphorus degrading enzyme with an affinity tag, and mixing, to obtain a mixture, and then subjecting the mixture to a separation, to obtain an organophosphorus degrading enzyme based multifunctional catalyst. According to the present disclosure, the method for preparing an organophosphorus degrading enzyme based multifunctional catalyst is simple in operation, and has a low cost; the multifunctional catalyst prepared by the same has low requirement for the purity of enzyme, support of which could be directionally binded with enzyme, and could be used for detecting an organophosphorus pesticide, and also for a cascade degradation of an organophosphorus pesticide. The final product p-aminophenol has important application value.
Use of metal-accumulating plants for the preparation of catalysts that can be used in chemical reactions
A method of implementing organic synthesis reactions uses a composition containing a metal catalyst originating from a calcined plant. The plants can be from the Brassicaceae, Sapotaceae and Convolvulaceae family, and the metal catalyst contains metal in the M(II) form such as zinc, nickel, manganese, lead, cadmium, calcium, magnesium or copper. Examples of the organic synthesis reactions include halogenations, electrophilic reactions, cycloadditions, transesterification reactions and coupling reactions, among others.

Mild catalytic reduction of C—O bonds and C═O bonds using a recyclable catalyst system
A method of reducing a CO bond to the corresponding CH bond in a substrate, which could be a benzylic alcohol, allylic alcohol, ester or an ether bond beta to a hydroxyl group or alpha to a carbonyl group using a recyclable metal catalyst system. The recyclable catalyst system is also applicable to reducing a CO bond to the corresponding COH bond and then CH bond. These methodologies can be linked in one-pot to selective oxidation and depolymerizations of aromatic polyols such as lignin.
