Oxidation of α-pinene over gold containing bimetallic nanoparticles supported on reducible TiO2 by deposition-precipitation method

High-temperature reduction improves the activity of rutile TiO2 nanowires-supported gold-copper bimetallic nanoparticles for cellobiose to gluconic acid conversion

“…Several industrially important oxidation reactions have been reported to occur over Au-Cu bimetallic catalysts [23], but detailed reports and studies on the role of supports, the importance of catalyst reduction in H 2 at high temperature, O 2 adsorption and activation sites and the essential role of H 2 O in the activation of O 2 in most liquid phase oxidation reactions of biomass-derived compounds to organic acids are limited. Especially, the basis of the promoting effect of the catalyst support on a bimetallic catalyst is still not understood completely.…”

“…This method has been reported to be a very effective in synthesizing Au/TiO 2 and Au-based bimetallic catalysts because of its efficacy to produce metal particle sizes of few nanometers [21][22][23][24]. 1D TiO 2 nanostructures, such as NWs have received appreciable attention for catalytic applications due to their peculiar physical properties, high crystallinity and thermal stability and they also offered unique opportunities for adjusting the material features to obtain special sites that can strongly affect activity of the catalyst [25,26].…”

Novel access to verbenone via ruthenium nanoparticles-catalyzed oxidation of α-pinene in neat water

“…verbenone with t-BHP in acetonitrile [30]. Finally, in the context of promising technologies development, the use of cleaner solvents as replacement of usual organic solvents also contributes to the efforts towards more eco-respectful oxidation processes [35].…”

“…-Scheme 1 -Up to now, various catalytic systems, either molecular complexes [16][17][18][19][20] or heterogeneous catalysts [21][22][23][24][25][26][27][28][29][30][31][32], have been used to produce verbenone. Nevertheless, in the most cases, low to medium yields were obtained ( Figure 1) or most of these processes still suffer from various drawbacks, such as sophisticated catalytic systems, toxic organic solvents and high amounts of oxidants, long reaction times, and difficult catalyst's recovery.…”

An Institutional Approach to Solar Fuels Research

“…One of the more successful areas is solar energy related research. This research covers projects involving the synthesis and application of nanomaterials such as carbon nanotubes [16][17][18] ; the production of organic optoelectronic devices [19][20][21] ; synthesis of industrial catalysts [22][23][24] ; fundamental studies on the mechanism of enzymes (such as photosystem II) [9,11,[25][26][27] ; elucidation of the genome sequence, metabolism and biomass formation of various species [28][29][30] ; combustion, gasification and torrefaction of biomass including ash behaviour [31][32][33][34][35][36][37] ; the improvement of biomass (wood) quantity and quality by breeding and genetic modification [38,39] ; and implementation of a biorefinery concept at industrial scale. [40][41][42][43][44][45] For building and maintaining these research facilities and efforts, internal and external funding is required.…”
