Hydrogen absorption on Ru/ZrO2 studied by FT-IR
Article Abstract:
Fourier transform infrared spectroscopy was used in studying the adsorption of hydrogen on Ru/ZrO2. The Ru/ZrO2 catalyst was prepared from Ru3(CO)12 based on the methods prescribed by Kubota and Izumi. ZrO2 was prepared by calcination of ZrO(OH)2 in air at 973 K for 4 hours. Results show that two IR bands at 1600/cm and at 3400/cm are formed from the introduction of H2(D2) on Ru(2.0 wt%)/ZrO2. The 1600 band was assigned to the delta(H2O) (delta(D2O)) mode while the 3200 band was associate with the stretching mode of the hydroxyl bond.

Characterization of Rh-Cr mixed-oxide nanoparticles dispersed on ([Ga.sub.1-x][Zn.sub.x])([N.sub.1-x][O.sub.x]) as a cocatalyst for visible-light-driven overall water splitting
Article Abstract:
Electron microscopy and X-ray spectroscopy are used to characterize the structure of Rh-Cr mixed-oxide ([Rh.sub.2-y][Cr.sub.y][O.sub.3]) nanoparticles dispersed on ([Ga.sub.1-x][Zn.sub.x])([N.sub.1-x][O.sub.x]). The structural analyses have indicated that the activity of this photocatalyst is strongly dependent on the generation of the trivalent Rh-Cr mixed-oxide nanoparticles with optimal composition and distribution.

Reply to "Comment on 'A study of mechano-catalysts for overall water splitting"'
Article Abstract:
A redox reaction mechanism between metal and metal oxide for the study of mechano-catlysts for overall water splitting reaction is presented. Tribocharging is expected to be highly dependent on the material used, suggesting that microplasma is a promising candidate for the mechanical water splitting mechanism.
