Human urine can be a cheap, durable and effective alternative to platinum-carbon as a catalyst for fuel cells

Human urine can be a cheap, durable and effective alternative to platinum-carbon as a catalyst for fuel cells | Jean Boulle Luxury | Scoop.it
Human urine, otherwise potentially polluting waste, is an universal unused resource in organic form disposed by the human body. We present for the first time “proof of concept” of a convenient, perhaps economically beneficial, and innovative template-free route to synthesize highly porous carbon containing heteroatoms such as N, S, Si, and P from human urine waste as a single precursor for carbon and multiple heteroatoms. High porosity is created through removal of inherently-present salt particles in as-prepared “Urine Carbon” (URC), and multiple heteroatoms are naturally doped into the carbon, making it unnecessary to employ troublesome expensive pore-generating templates as well as extra costly heteroatom-containing organic precursors. Additionally, isolation of rock salts is an extra bonus of present work. The technique is simple, but successful, offering naturally doped conductive hierarchical porous URC, which leads to superior electrocatalytic ORR activity comparable to state of the art Pt/C catalyst along with much improved durability and methanol tolerance, demonstrating that the URC can be a promising alternative to costly Pt-based electrocatalyst for ORR. The ORR activity can be addressed in terms of heteroatom doping, surface properties and electrical conductivity of the carbon framework.

The Boulle Luxury Experience: Sun King TM Diamond Coating In March 2016, after years of investment in research and subsequent development of its proprietary diamond coating technology, the Jean Boulle Luxury Group ("Boulle Luxury")  announced the launch of its patent-pending  Sun King Diamond Coating for luxury finishes, and confirmed the delivery of its first multi-million diamond-coated car finish in Geneva. In March 2017, Boulle Luxury announced that its High Tech. luxury diamond finish technology had been used in a paint exhibited on a Rolls-Royce Ghost Elegance (EWB) at the 2017 Geneva International Motor Show (GIMS).  Boulle Luxury worked with the Bespoke division of Rolls Royce Motor Cars Limited (www.rolls-roycemotorcars.com) to import the sea diamonds from Namibia and to produce the diamond compound in Holland  and Germany that was used on the  car displayed by Rolls Royce Motor Cars Limited at the 2017 Geneva International Motor Show. http://Boulle.co/ha2y9   The proprietary, patent-pending Boulle Luxury finish enables ultra high-end producers of luxury automobiles, executive jets and superyachts to offer a diamond-inlay coating that is unsurpassable in strength and absolutely incomparable in beauty and visual depth. When applying the Boulle Luxury Diamond Finish, the existing paintwork is not affected and remains in situ whilst the topcoat is chemically removed and replaced with our patent-pending diamond coating. The Chairman, C.E.O. and Directors of the Jean Boulle Luxury Group include a number of former De Beers Executives who have since 2016 expanded the Group’s diamond technology from Luxury Cars into the SuperYacht and Aerospace Sectors.  Disclaimer : this page is not intended for any specific nationality or jurisdiction.
