Oxidation of methanol was studied in alkaline solution on bimetallic Ir/Pt(poly) catalysts prepared by the spontaneous deposition of Ir on polycrystalline Pt. Nano-scale surface properties of Ir/Pt(poly) catalysts were revealed by ex situ Atomic Force Microscopy imaging. Modified electrodes were characterized in situ electrochemically by cyclic vol...

Electrochemical synthesis has been presented as a powerful technique to produce nanoparticles. However, it has been especially focused on noble metal particles, while few studies have been done on oxides production. On the other hand, when partially doped with trivalent cations at the barium sublattice, BaTiO₃-based ceramics are well known to exhib...

Formation mechanism of synthesizing nanoparticle tungsten carbide (WC) was studied. WC was synthesized by carbothermal hydrogen reduction (CHR) method under various reaction temperatures for holding different post-treatment time in 20% (v/v) CH₄/H₂. The phase transformation mechanism of gaining WC was investigated, by combining CHR with X-ray diffr...

In this work, MoS₂ nanosheets (NSs) are applied as a novel anode to deliver a high-performance supercapacitor (SC). A MoS₂ NSs anode with a special honeycomb-shaped structure, is synthesized using a hydrothermal method, and subsequently applied in conjunction with an electrodeposited Co(OH)₂ NSs cathode to create a new cost-effective aqueous hybrid...

The layered potassium niobate, K₄Nb6O17, is known as a photocatalyst for hydrogen production from water splitting under UV light. Here we show that potassium niobate nanosheets can be obtained by exfoliation of K₄Nb6O17 followed by proton exchange. Photocatalytic water splitting has been improved in this work by loading Rh nanoparticles as cocataly...
