摘要： A photocatalytic reactor includes a polymeric side-emitting optical fiber having a coating with a photocatalyst embedded in a porous polymer, a light source optically coupled to the polymeric side-emitting optical fiber and configured to irradiate the photocatalyst, and a multiplicity of oxygen-permeable hollow-fiber membranes. The polymeric side-emitting optical fiber and the multiplicity of oxygen-permeable hollow-fiber membranes are configured to be at least partially immersed in water. When at least partially immersed in water, the multiplicity of oxygen-permeable hollow-fiber membranes is configured to provide dissolved molecular oxygen to the water, and the coating is configured to allow diffusion of the dissolved molecular oxygen into the coating and to allow diffusion of hydrogen peroxide out of the coating.

摘要： The present invention relates to carbon fiber composites and a method for producing the same. By reducing specific transition metal ions with a specific concentration, the method for producing the carbon fiber composites can form nanoparticles of a transition metal on an outer surface of a titanium dioxide layer encapsulating a carbon fiber to produce the carbon fiber composites. The nanoparticles of the transition metal directionally contact the titanium dioxide layer, so that the carbon fiber composites have synergistically photocatalytic activity.

摘要： A transparent ceramic substrate is covered by a photocatalyst layer, at least partially. The photocatalyst layer includes a semiconductor material that, upon exposure to electromagnetic radiation, forms a plurality of electrons and a plurality of holes that remain confined to the photocatalyst layer. The transparent ceramic substrate has a diameter that is larger than the wavelength of the electromagnetic radiation for light trapping.

摘要： Methods for the photocatalytic reduction of alkynes to alkenes with high conversion yields and selectivities using a heterogeneous system that incorporates a cobalt-porphyrin into a metal-organic framework (MOF) are provided. The cobalt-porphyrin-based MOFs carry out the photocatalytic reductions in the presence of a visible-light activated photosensitizer molecule and a sacrificial electron donor.
