A catalyst model comprising platinum nanoparticles deposited on a TiO(2)(110) wafer was prepared in a vacuum, transferred in air, and characterized with a Kelvin probe force microscope placed in a N(2) environment. The topography and local work function of individual nanoparticles were observed with single-nanometer resolution in the N(2) environment of one atmosphere pressure. Some nanoparticl...

Scalable and sustainable solar hydrogen production through photocatalytic water splitting requires highly active and stable earth-abundant co-catalysts to replace expensive and rare platinum. Here we employ density functional theory calculations to direct atomic-level exploration, design and fabrication of a MXene material, Ti3C2 nanoparticles, as a highly efficient co-catalyst. Ti3C2 nanoparti...

Freestanding graphene membranes were successfully functionalized with platinum nanoparticles (Pt NPs). High-resolution transmission electron microscopy revealed a homogeneous distribution of single-crystal Pt NPs that tend to exhibit a preferred orientation. Unexpectedly, the NPs were also found to be partially exposed to the vacuum with the top Pt surface raised above the graphene substrate, a...

The present work describes a new approach to directly electrodeposit platinum nanoparticles on the surface of multi-walled carbon nanotubes (MWNTs) through cyclic potential scanning technique and to prepare a novel carbon nanotubes including platinum nanoparticles modified electrode (noted as Pt/MWNTs). TEM image shows that Pt nanoparticles are attached on the out surface of the MWNTs with aver...

ZnO (8-10 nm), gold (10-50 nm), and platinum (2-5 nm) nanoparticles were deposited on monoliths of regularly arranged three-dimensional (3D) carbon nanotubes of 40 nm diameter and length up to 30 microm. The single-source precursor complex di-aqua-bis[2-(methoxyimino)propanato](2)Zn(ii) in dimethylformamide was used for the deposition of nanoparticulate ZnO on an ordered 3D CNT scaffold by solu...

The effects of metal depositions on pyrolyzed photoresist films (PPF) grown on silicon substrates were investigated. A silicon chip, spin-coated with a positive photoresist was pyrolyzed through heating to form a PPF, or a conductive carbon film. For increasing periods of time, nanometersized metal particles of platinum and palladium were spontaneously deposited on conductive carbon films by im...

Bio-directed synthesis of nanoparticles is an interesting field of rapid advancement for biologists,chemists and materials scientists, especially in light of efforts to find out green methods of inorganicmaterial synthesis. In the present study, green synthesis of platinum nanoparticles (PtNPs) using sheepmilk is reported for the first time. By adjusti...
