To obtain the PtRu/C electrocatalysts, surfactant-free (wet) synthesis methods have been used. The structural-morphological characteristics and electrochemical behavior of catalysts studied. possibility ranging crystallite size from 1.2 to 4.5 nm using different reducing agents (ethylene glycol, ethanol, isopropanol) has shown. effect both particles’ mass fraction metal component on surface are...

Designing efficient anode CO-tolerant electrocatalysts is critical in low-temperature fuel cell catalysts fueled either by H2/CO or alcohol. We demonstrate that the incorporation of TiO2 nanocubes (TiO2NCs) on Carbon Vulcan supports, followed synthesis Pt NPs at their surface (Pt/TiO2NCs-C material), led to improvements performance towards electrooxidation carbon monoxide, ethanol, methanol, et...

caffeic acid phenethyl ester(cape) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. a group of heterocyclic esters of caffeic acid was synthesized using mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catechol...

The pathway of formic acid electrooxidation strongly depends on the amount of three neighbouring Pt or Pd atoms in the surface of Pd- or Pt-based catalysts. Here, Pt decorated Pd/C nanoparticles (the optimal atomic ratio, Pd : Pt = 20 : 1) were designed and then synthesized through a facile galvanic replacement reaction where the amount of three neighbouring Pt or Pd atoms markedly decreased. A...
