‘HOT’ paper – carbon riveted Pt/TiO₂–C exhibits excellent stability

The significantly enhanced stability for carbon riveted Pt/TiO2–C catalyst is ascribed to:

(1) the excellent stability of anatase TiO₂
(2) the strong metal-support interaction between Pt and TiO₂
(3) the anchoring effect of the carbon layers formed during the carbon riveting process

These findings indicate that it is a promising catalyst for proton exchange membrane fuel cells which are under long term operation.

Matthew Eisaman and colleagues have performed a comprehensive experimental investigation of CO₂ gas regeneration from aqueous potassium carbonate and bicarbonate solutions using bipolar membrane electrodialysis (BPMED). This system allows the regeneration of pure CO₂ gas, suitable for subsequent sequestration or reaction to synthetic hydrocarbons and their products.
