Ru/CeO_2[RC] and Ru/CeO_2/ethylene glycol（EG） [RCE] nanoparticles were produced by performing a simple hydrothermal reaction at 200℃ for 24 h and found to have two distinct morphologies. The RC nanoparticles are phase pureCeO_2; triangular highly crystallineCeCO_3OH nanoparticles are formed from the solution containing EG under the same hydrothermal reaction conditions at p H 8.5. EG plays an important role in the formation of the triangularCeCO_3OH nanoparticles. The polycrystallineCeCO_3OH nanoparticles retain their triangular structure even after calcination at 600℃in air but are transformed into a pureCeO_2 phase. The room temperature photoluminescence of the RC and RCE nanoparticles and of RCE calcined at 600℃[RCE-600] was also investigated. It was found that the high crystallinity triangular RCE-600 sample exhibits the highest photoluminescence intensity.

The rate of Methanol synthesis over a Cu/ZnO/Al2O3 (60:30:10) catalyst has been measured using CO2/H2 (10:90) and CO/CO2/H2 (10:10:80) streams at 433, 443, 453, 463 and 473 K. Using the CO2/H2 stream, it requires 12 × 103 s to achieve steady-state performance;this time reduces to 5.4 × 103 s on increasing the temperature to 463 K. Using the CO/CO2/H2 stream, steady State performance is not achieved even after 14.4 × 103 s at 433 K but is achieved after 9 × 103
