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： A method of synthesizing a doped carbonaceous material includes mixing a carbon precursor material with at least one dopant to form a homogeneous/heterogeneous mixture; and subjecting the mixture to pyrolysis in an inert atmosphere to obtain the doped carbonaceous material. A method of purifying water includes providing an amount of the doped carbonaceous material in the water as a photocatalyst; and illuminating the water containing the doped carbonaceous material with visible light such that under visible light illumination, the doped carbonaceous material generates excitons (electron-hole pairs) and has high electron affinity, which react with oxygen and water adsorbed on its surface forming reactive oxygen species (ROS), such as hydroxyl radicals and superoxide radicals, singlet oxygen, hydrogen peroxide, that, in turn, decompose pollutants and micropollutants.

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.
