Different solids consisting in hydrous zirconia were synthesized by the water in oil microemulsion technique (ME series). For comparative purposes, diverse solids were also obtained by the conventional sol-gel method (P-series). The solids were teste

Two different C-3 alcohols (glycerol and propan-2-ol) were tested as sacrificial agents for H 2 photocatalytic production on M/TiO 2 (M = Pt, Pd and Au) solids. In all cases, synthetic methods led to average metal particle sizes in the 2–5 nm range

Different Pt-based systems (5% by weight) were obtained through impregnation of chloroplatinic acid on Al 2 O 3 , CeO 2 , La 2 O 3 and ZnO. The solids were tested for glycerol hydrogenolysis. Results showed that metal sites are needed both for dehydr

The liquid-phase selective reduction of crotonaldehyde to crotyl alcohol was studied on Pt/ZnO. Optimization through factorial design of experiments led to a 75% increase in the yield to crotyl alcohol and solvent was found to be the most influential

The effect of iron content (Fe/Al molar ratio = 0.01–1 equivalent to the iron percentages from 0.5 to 20.5 wt%) and thermal treatment (450–650 °C) of aluminium-iron phosphates, prepared by an ammonia gelation method, on their catalytic performan
