By Christian Hageluken Umicore AG & Co KG, Rodenbacher Chaussee 4, D-63457 Hanau Wolfgang, Germany Email: christian.hagelueken@eu.umicore.com The high technical recyclability of platinum group metals means that over 95% recovery can be achieved once pgm-containing scrap reaches a state-of-the-art refi ning facility. Technical challenges exist, but the main barriers to recycling pgms lie in ensuring the collection of scrap and in the capacity and technical capabilities of recycling chains around the world. Economic and legislative drivers are also signifi cant. The “seven conditions” for effective recycling and their impact within Europe are discussed in this article; industrial applications are found to lead the way in terms of recycling rates while automotive and particularly electronic areas are currently some way behind. New business models are recommended, to enable precious metal-containing waste to be seen as a valuable resource and ensure the sustainability and security of pgms supply for the future.
德国哈瑙沃尔夫冈，Umicore AG & Co KG, Rodenbacher Chaussee 4, D-63457电子邮件:christian.hagelueken@eu.umicore.com铂族金属的高技术可回收性意味着，一旦含铂的废料到达最先进的精炼设施，回收率可以达到95%以上。技术上的挑战是存在的，但是回收废旧金属的主要障碍在于确保废料的收集以及世界各地回收链的能力和技术能力。经济和立法驱动因素也很重要。本文讨论了有效回收的“七个条件”及其在欧洲的影响;工业应用被发现在回收率方面处于领先地位，而汽车，特别是电子领域目前有些落后。建议采用新的商业模式，使含贵金属废物被视为一种宝贵的资源，并确保未来铂类金属供应的可持续性和安全性。

Johnson Matthey India Pvt Ltd, Plot 12, Sector 3, IMT Manesar, 122050, Haryana, Gurgaon, India Email: kapoorm@mattheyasia.com Introduction The 2nd Diesel Emissions Conference India 2011, held in Delhi on 5th–7th September 2011 (1), brought together over 200 leading stakeholders from India and beyond to discuss the industry’s progress in meeting the Bharat Stage III and IV legislation which also applies to commercial vehicle diesel applications over 3.5 tonnes (2). The conference also showcased the latest emissions reduction technologies being used in India and across the world, and acted as a platform for networking among Indian diesel emission industry delegates. There were 27 presentations given over three days which included topics such as: Government strategy for supplying Bharat Stage IV (BS IV) diesel fuel; The crucial development of AUS 32 (aqueous urea solution, 32.5%, also known as AdBlue®) supply infrastructure and AUS 32 price analysis in India; New fuel economy standards in India and their impact on the automotive industry; Emissions control for onand off-road vehicles in India to further improve air quality; Case study on the implementation of Euro IV in China and lessons for the Indian market. This review focuses on the use of selective catalytic reduction (SCR) technology for controlling diesel nitrogen oxides (NOx) emissions and the development of the AUS 32 market in India. Papers can be purchased from the Diesel Emissions Conference website (1).

To improve the high temperature properties, platinum can be hardened by solid solution and/or oxide parti-cles. The investigated alloy, dispersion hardened plati-num-5% rhodium (Pt-5%Rh DPH), was produced via melting and subsequent annealing of the semi-fi nished product in order to obtain an oxide particle dispersion. Despite the relatively large oxide particles formed in this process, the creep strength is much higher in com-parison to conventional Pt-5%Rh. The aim of this paper is to study the strengthening mechanisms in the alloy Pt-5%Rh DPH by transmission and scanning electron microscopy. The size distribution of oxide particles shows a bimodal distribution, and the average oxide particle diameter is 315 nm for particles larger than 150 nm. For particles between 25 nm and 150 nm the average diameter is 49 nm. The size ranges of oxide par-ticles are not substantially affected by high temperature creep deformation, but particles of

It was found that it is not suffi cient to use the analysis of X-ray absorption near edge structure (XANES) alone to determine the nature of species present in fresh and road aged catalysts. Detailed analysis of the extended X-ray absorption fi ne structure (EXAFS) revealed the presence of a mixture of oxidic and metallic species in the fresh catalysts. Metallic components were predominantly found in the road aged catalysts. The present study did not fi nd any chloroplatinate species in the systems investigated.
