In this paper, pure and Au-deposited ZnO nanoparticles with different Au content were prepared and characterized. The effect of Au content on the PL properties and photocatalytic activity of CO oxidation was mainly investigated. The results showed that Au deposition can greatly decrease the...

TiO2 samples with different crystal forms were treated in flowing NH3 at elevated temperatures to fabricate N-doped TiO2 photocatalysts with different crystal forms. The resulting N-doped TiO2 photocatalysts were characterized by means of X-ray diffraction, transmission electron microscopy,...

Catalytic refining of bio-oil by reacting with olefin/alcohol over solid acids can convert bio-oil to oxygen-containing fuels. Reactivities of groups of compounds typically present in bio-oil with 1-octene (or 1-butanol) were studied at 120 °C/3 h over Dowex50WX2, Amberlyst15, Amberlyst36,...

Crude bio-oil from pine chip fast pyrolysis was upgraded with olefins (1-octene, cyclohexene, 1,7-octadiene, and 2,4,4-trimethylpentene) plus 1-butanol (<i>iso</i>-butanol, <i>t</i>-butanol and ethanol) at 120 °C using a silica sulfuric acid (SSA) catalyst that possesses a good catalytic activity and...
