Pt-based alloy catalysts are promising candidates for fuel-cellapplications, especially for cathodic oxygen reduction reaction (ORR) and anodic methanol oxidation reaction (MOR). The rational design of composition and morphology is crucial to promoting catalytic performances. Here, we report the synthesis of Pt–Co nanoframes via chemical etching of Co from solid rhombic dodecahedra. The ...

Flotation tests ofmanganese orewere carried out to investigate collectingperformanceof the novel synthesized LHA compound. The samples were ground to 90% passing 74 μm. The pulp was conditioned at 25 wt.% solids in an XFD-type laboratoryflotation cellwith a volume of 0.75 L for 3 min and the impeller speed was fixed at 2000 rpm.
