The present invention relates to a process for preparing hydridocarbonyltris(triphenylphosphine)rhodium(l), RhH(CO)(PPh3)3, also referred to hereinafter as Rh-hydrido. An alcoholic suspension of triphenylphosphine is stirred with an Rh(III) chloride precursor at elevated temperature. The Rh(III) chloride precursor used may be rhodium(III) chloride hydrate RhCl3*xH2O or rhodium(III) chloride solution H3[RhCl6]*(H2O)n. After cooling, alcoholic alkali metal hydroxide solution is added, and the mixture is stirred for a few hours. Finally, sparging is effected with CO gas and the Rh-hydrido formed is removed. Rh-hydrido can be prepared by this process on the industrial scale in high yields and with very good quality.

A lithium ion battery is obtained by using a negative electrode material for lithium ion battery comprises a composite material comprising silicon-containing particles, graphitic carbon material particles, and a carbonaceous carbon material, in which the composite material has a ratio (A/B) of an area (A) of a peak near 100 eV derived from metal Si to an area (B) of a peak near 103 eV derived from silicon oxide, as measured by XPS, of not less than 0.10 and not more than 2.30.


The present invention is directed to a catalyst system for the reduction of the harmful exhaust-gas constituents hydrocarbons (THC), carbon monoxide (CO), nitrogen oxides (NOx), and the environmentally detrimental secondary emissions ammonia (NH3) and nitrous oxide (N2O), of combustion engines operated using gasoline, and to a corresponding method for exhaust-gas purification. The system is characterized by a particular arrangement of catalysts, and is used in the case of engines which are operated with predominantly, on average, stoichiometric air/fuel mixtures. Here, a three-way catalyst produced in accordance with the current prior art is preferably installed in a close-coupled position. In the underfloor position there is situated an SCR catalyst produced in accordance with the current prior art, followed by a further three-way catalyst produced in accordance with the current prior art. The three-way catalyst in the underfloor region furthermore has a lower oxygen storage capacity than the close-coupled three-way catalyst.

METGROW\ will address and solve bottlenecks in the European raw materials supply by developing innovative metallurgical technologies for unlocking the use of potential domestic raw materials. The METGROW\ consortium has received an EIP RM Commitment status. The consortium is supported by internationally respected research institutes and universities. Many of the partners (9) are members of EIT KIC Raw Materials consortium as well. The value chain and business models for metal recovery from low grade ores and wastes are carefully looked after. Within this project, both primary and secondary materials are studied as potential metal resources. Economically important nickel-cobalt deposits and low grade polymetallic wastes, iron containing sludges (goethite, jarosite etc.) which are currently not yet being exploited due to technical bottlenecks, are in focus. Concurrently, METGROW\ targets innovative hydrometallurgical processes to extract important metals including Ni, Cu, Zn, Co, In, Ga, Ge from low grade ores in a cost-effective way. In addition a toolbox for metallurgical system is created in the project using new methods and combinations. The unused potential of metal containing fine grained industrial residues are evaluated, while hybrid and flexible hydrometallurgical processes and treatment methods of fines are developed for both materials. Training and education of new professionals are facilitated within the METGROW\ project. The knowledge of raw materials and sustainable technologies will attract new talents in the field who can flexibly change fields from treatment of secondary to primary resources, which also smoothens the economic ups and downs in the primary sector.
