(1), (2) and (5). Figure 6 shows the gas responses to 25 ppm CO and 1 ppm HCHO gases with the working temperature in situ, which is obtained by the fabricated micro gas sensor using SnO2 thin film sensing materials with Pt T sensor (see also Table 1).
Proton form of MCM-48 mesoporous material along with Pt on this support and Ru on carbon was tested.
In comparison, the decoration of Pt on the non-doped graphene (RGO) yielded a composite material with larger Pt (7.8 nm) and poorer size distribution.
We demonstrate that the supporting substrate plays a crucial role in interaction of these materials with water, with Pt making both GO and RGO insensitive to humidity variations and change in environment.
The 3D Fe3O4/carbon materials can be loaded with Pt nanoparticles without adding any reducing agent; Pt-loaded 3D Fe3O4/carbon hybrid materials have superior electrochemical catalytic activity toward methanol oxidation and the oxidation current density on them is nearly triple that on a commercial Pt/C catalyst.
Sensitized with Pt nanoparticles, the material promotes solar spectrum photoconversion of CO2 to CH4 with an apparent quantum yield of 12.40% and a time normalized CH4 generation rate of 80.35 μmol g−1 h−1, which to the best of our knowledge is a record for photocatalytic-based CO2 reduction.
In contrast, TbFe2 does not crystallize properly on Pt, a material with a lower stiffness than Mo.
This material, with a high amount of Pt (20 wt.%), was used as a metal support in mechanical mixtures with the acidic zeolite, H-erionite, and tested for the conversion of n-hexane.
Field electron emission experiments with emitters built with Pt and Au precursor materials were conducted.
For the proposed abiotic system the cathode material is constructed from nitrogen doped graphene decorated with Pt NPs.
