(A) SEM of Pt/TiО2/WO3 catalyst, obtained by galvanic replacement of photodeposited Cu onto electrosynthesized TiО2/WO3 layers with Pt;(B) TEМ image of Pt(Ni)/TiO2_C nano-catalyst, obtained by galvanic replacement of electroless plated Ni onto TiO2 and carbon nanoparticles with Pt. Pt loading is decreased.
|Electrocatalytic oxidation of methanol (A) and CO (B) on electrodes with Pt(Ni)TiO2_C catalyst. The higher activity of bi-metallic composite catalysts is due to synergy of Pt and TiO2.|
DSC and magnetic behavior of electroless Co-W-P alloy.
|SAXS study of nucleation and growth of Au particles in soda-lime glass. Ex situ and in situ annealing under x-ray irradiation: volume fraction (a), mean particle radius (b) and particle number density (c) as a function of the ex situ and in situ annealing time at 550oC (left) and in situ (right) annealing time at various temperatures. The lines are a guide to the eyes only. D. Tatchev, A. Hoell, M. Eichelbaum, K. Rademann, Physical Review Letters 106, 085702 (2011).|
