摘要： A robust and general method is provided to synthesize noble metal-based amorphous-crystalline heterophase nanoparticles, each having an amorphous noble metal core and a crystalline semiconductor/metal shell or a Janus structure with an amorphous noble metal domain and a crystalline metal domain attached side by side with the amorphous noble metal domain (i.e., snowman-like structure). The as-synthesized heterophase nanoparticles not only exhibit superior activities in diverse catalytic reactions but also show unexpected high stability, which could be used as ideal templates for the seeded growth of other nanostructures, thus show tremendous potential in different applications including electrocatalysis and photocatalysis. With efficiently separated photo-induced electron and photo-induced holes, superior catalytic performance of amorphous nanomaterials, efficient solar energy conversion ability of crystalline semiconductors, as well as the synergistic effect between them, the controlled construction of amorphous noble metal-crystalline semiconductor heterostructures can be a promising route to development of high-performance catalysts towards photocatalytic reactions.

摘要： The present invention is directed, at least in part, to a process for improving the efficiency of a photocatalyst (a semiconductor photocatalyst) by tethering (depositing) a metal (e.g., metal ions of a late transition metal, such as nickel) to the semiconductor (photocatalyst) surface through the use of an organic ligand. More specifically, 1,2-ethanedithiol (EDT) functions as an excellent molecular linker (organic ligand) to attach a transition metal complex (e.g., nickel (Ni2+ ions)) to the semiconductor surface, which can be in the form of a cadmium sulfide surface. The photocatalyst has particular utility in generating hydrogen from H2S.

摘要： Methods and systems for hydroprocessing heavy oil feedstocks to form an upgraded material involve the use of a colloidal or molecular catalyst dispersed within a heavy oil feedstock, a pre-coking hydrocracking reactor, a separator, and a coking reactor. The colloidal or molecular catalyst promotes upgrading reactions that reduce the quantity of asphaltenes or other coke forming precursors in the feedstock, increase hydrogen to carbon ratio in the upgraded material, and decrease boiling points of hydrocarbons in the upgraded material. The methods and systems can be used to upgrade vacuum tower bottoms and other low grade heavy oil feedstocks. The result is one or more of increased conversion level and yield, improved quality of upgraded hydrocarbons, reduced coke formation, reduced equipment fouling, processing of a wider range of lower quality feedstocks, and more efficient use of supported catalyst if used in combination with the colloidal or molecular catalyst, as compared to a conventional hydrocracking process or a conventional thermal coking process.

摘要： A process for slurry hydrocracking catalyst recovery is described. In one embodiment, the process includes separating effluent from a slurry hydrocracking zone into a first portion comprising solvent and clarified pitch and a second portion comprising pitch and catalyst. The second portion is contacted with an acid to leach the catalyst out of the pitch forming an aqueous solution and pitch residue. The aqueous solution is contacted with an anion to form an insoluble salt which is the catalyst.
