BACKGROUND Electro-oxidation of methanol in acidic solution was investigated on a Pt/SnO2 based electrocatalyst obtained by the sol-gel method. Pt/SnO2 systems were prepared by one pot synthesis using a sol-gel method and tin (IV) acetate as a precursor of SnO2 and water solution of hexachloroplatinum acid as a source of metallic phase. RESULTS The described method, thanks to its simplicity a...

In this paper we report synthesis of Au-SnO2 nanocomposite by nano-joining. It involves synthesis of Au and SnO2 colloids separately followed by post irradiation of mixed Au-SnO2 colloids. We have used 532 nm and 1064 nm wavelengths of a pulsed Nd:YAG laser and different post irradiation time. The post irradiation by 532 nm laser light results in formation of Au-SnO2 nanocomposite by nanojoinin...

The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has seen effective performance upgrades, showing remarkable academic research and commercial application value. Compared with silicon cells, the PCE gap is narrowing. However, stability, cost, large-scale production are still far behind. For scale-up preparing high-efficiency stable PSCs, there a variety related from each fu...

Transparent conducting oxides (TCOs) are a crucial component of solar cells. Tin-doped indium oxide (ITO) is the most employed TCO, but scarcity and high price induce search for lower-cost TCOs with equivalent properties as substitutes. Tin dioxide (SnO2) films have many advantages, such rich sources material, low prices, nontoxicity. SnO2 present visible-light transmittance, near-infrared ligh...
