The Catalytic Valorization of Lignin for the Production of Renewable Chemicals

Abstract: Biomass is an important feedstock for the renewable production of fuels, chemicals, and energy. As of 2005, over 3% of the total energy consumption in the United States was supplied by biomass, and it recently surpassed hydroelectric energy as the largest domestic source of renewable energy. Similarly, the European Union received 66.1% of its renewable energy from biomass, which thus surpassed the total combined contribution from hydropower, wind power, geothermal energy, and solar power. In addition to energy, the production of chemicals from biomass is also essential; indeed, the only renewable source of liquid transportation fuels is currently obtained from biomass.

Meeting the Clean Energy Demand: Nanostructure Architectures for Solar Energy Conversion

Abstract: The increasing energy demand in the near future will force us to seek environmentally clean alternative energy resources. The emergence of nanomaterials as the new building blocks to construct light energy harvesting assemblies has opened up new ways to utilize renewable energy sources. This article discusses three major ways to utilize nanostructures for the design of solar energy conversion devices: (i) Mimicking photosynthesis with donor−acceptor molecular assemblies or clusters, (ii) semiconductor assisted photocatalysis to produce fuels such as hydrogen, and (iii) nanostructure semiconductor based solar cells. This account further highlights some of the recent developments in these areas and points out the factors that limit the efficiency optimization. Strategies to employ ordered assemblies of semiconductor and metal nanoparticles, inorganic-organic hybrid assemblies, and carbon nanostructures in the energy conversion schemes are also discussed. Directing the future research efforts toward utiliza...

Mechanism of oxidation reactions catalyzed by cytochrome p450 enzymes.

Abstract: ion phase that leads to an alkyl radical coordinated to the iron-hydroxo complex by a weak OH---C hydrogen bond, labeled as CI; (ii) an alkyl (or OH) rotation phase whereby the alkyl group achieves a favorable orientation for rebound; and (iii) a rebound phase that leads to C-O bond making and the ferric-alcohol complexes, 4,2P. The two profiles remain close in energy throughout the first two phases and then bifurcate. Whereas the HS state exhibits a significant barrier and a genuine TS for rebound, in the LS state, once the right orientation of the alkyl group is achieved, the LS rebound proceeds in a virtually barrier-free fashion to the alcohol. As such, alkane hydroxylation proceeds by TSR,70-72,120 in which the HS mechanism is truly stepwise with a finite lifetime for the radical intermediate, whereas the LS mechanism is effectively concerted with an ultrashort lifetime for the radical intermediate. Subsequent studies of ethane and camphor hydroxylation by the Yoshizawa group117,181-183 arrived at basically the same conclusion, that the mechanism is typified by TSR. The differences between the results of Shaik et al.130,173,177-180 and Yoshizawa et al.117,181-183 were rationalized recently71,72 and shown to arise owing to technical problems and the choice of the mercaptide ligand,117,181-183 which is a powerful electron donor and is too far from the representation of cysteine in the protein environment. The most recent study of camphor hydroxylation, which was done at a higher quality,117 converged to the picture reported by Shaik et al.130,173,177-180 and shows a stepwise HS process with a barrier of more than 3 kcal/mol for C-O bond formation by rebound of the camphoryl radical vis-à-vis an effectively concerted LS process for which this barrier is 0.7 kcal mol-1 and is the rotational barrier for reaching the rebound position. By referring to Figure 21, it is possible to rationalize the clock data of Newcomb in a simple manner. The apparent lifetimes are based on the assumption that there is a single state that leads to the reaction, such that the radical lifetime can be quantitated from the rate constant of free radical rearrangement and the ratio of rearranged to unrearranged alcohol product. However, in TSR, the rearranged (R) product is formed only/mainly on the HS surface, while the unrearranged (U) product is formed mainly on Figure 20.
