Precious Metal Refining & Recovery, Episode 10: Platinum From the Road
Developing low-cost, efficient processes for recovering and recycling palladium, gold and cobalt metals from urban mine remains a significant challenge in industrialized countries. A simple, general method for preparing MSAs based on using high-order mesoporous monolithic scaffolds was described. Hierarchical cubic Ia 3 d wagon-wheel-shaped MSAs were fabricated by anchoring chelating agents colorants into three-dimensional pores and micrometric particle surfaces of the mesoporous monolithic scaffolds. Furthermore, the controlled assessment processes described herein involve evaluation of intrinsic properties e. Results show evidence that MSAs will attract worldwide attention as a promising technological means of recovering and recycling palladium, gold and cobalt metals. Driving forces for the booming use of platinum group metals PGM are their extraordinary and sometimes exclusive properties, which make them essential components in a broad range of applications. PGMs can play a part in building a sustainable society, and these materials are used in a variety of contemporary applications and products: chemical process catalysis, automotive emissions control, information technology, consumer electronics, fine jewelry, preparation of dental materials, photovoltaic fuel cells, and lithium ion batteries LIB

A sizeable number of organic moieties with potential functional active sites are strongly anchored onto the wagon wheel pore surfaces via H-bonding and dispersive interactions with retention of the cubic Ia 3 d geometry, as evidenced by the Bragg reflection planes hkl Figure 2A.
