in the present work, the electrooxidation of formic acid and formaldehyde; potentially important fuels for future fuel cells, was investigated on the fe3o4@pt core-shell nanoparticles/carbon-ceramic electrode (fe3o4@pt/cce). the fe3o4@pt nanoparticles were prepared via a simple and fast chemical method and their surface morphology, nanostructure properties, chemical composition, crystal phase, ...

An array of Pd–W alloys was fabricated, and the electrocatalytic activity of the alloys for the oxygen reduction reaction (ORR) in acidic media was screened by scanning electrochemical microscopy. The Pd0.7W0.3 showed the highest activity for the ORR, close to that for Pd0.8Co0.2 and Pt. A Pd–W electrocatalyst loaded on carbon black was formed by the NaBH4-reduction method, exhibiting high acti...

Chlorinated aromatic compounds are important raw materials or intermediates in many industries, but they highly toxic and difficult to degrade the natural environment. Electrocatalytic dechlorination technology can transform chlorinated with high toxicity into substances low easy degradation, so it has broad application prospects. Compared other metal catalysts, Pd-based catalysts have highest ...

Oxidation of formaldehyde (HCHO) is very important, owing to its use in fuel cells. Modification of electrodes surfaces is an excellent way to decrease the overpotentials as well as to increase the current density of the voltammetric response.pt as most efficient metal catalyst can easily be poisoned by product of oxidation and also it has high cost. In this work an efficient and low cost elect...

Structure effects of NiS and Ni3S2 nanoparticles were investigated for their electrocatalytic activity in the hydrogen evolution reaction in both acid and alkaline media. Owing to the different atomic configurations and crystalline structures, there is a hydrogen adsorption energy difference, which induces a difference in the activity. From density functional theory calculations and experimenta...

Herein we report the electrocatalytic activity of boron-doped graphene for the reduction of CO2. Electrolysis takes place at low overpotentials leading exclusively to formate as the product (vis-à-vis benchmark Bi catalyst). Computational studies reveal mechanistic details of CO2 adsorption and subsequent conversion to formic acid/formate.

We report an ultrasensitive DNA sensor using the rapid enhancement of electrocatalytic activity of DNA-conjugated Pd nanoparticles (NPs); the rapid enhancement results from the fast catalytic hydrolysis of NaBH(4) on Pd NPs and subsequent fast hydrogen sorption into Pd NPs.

Electroless deposition of a quasi-monolayer (q-ML) of Pt and/or Pd on different Au substrates is achieved by using CO as both reducing and quenching agents, imparting Au@Pt/C or Au@Pd/C with superior electrocatalytic activity for ethanol oxidation in alkaline media.

We report nanostructure electrodes for methanol electrooxidation by means of the co-sputtering deposition method. The Pt-WC-WO(3) three-phase electrode has higher I(f)/I(b) and oxidation current density i.e. improved electrocatalytic activity in comparison with those of pure Pt and two-phase electrodes because of both catalysis of tungsten carbide and size-control by tungsten oxide.
