The invention discloses a hydroxyl-rich ruthenium / titanium dioxide catalyst as well as a preparation method and application thereof, and the preparation method comprises the following steps: step 1, loading a ruthenium precursor on a titanium dioxide carrier by adopting an impregnation method or a deposition-precipitation method, and drying and calcining to obtain a Ru / TiO2 catalyst; and step 2, placing the Ru / TiO2 catalyst in an atmosphere environment containing water vapor or forming a physical adsorption water film on the surface of the Ru / TiO2 catalyst, and performing ultraviolet irradiation treatment to obtain the Ru / TiO2 catalyst. According to the method, water is physically adsorbed through ultraviolet light dissociation, hydroxyl is directly generated on the surface of Ru / TiO2 in an in-situ mode, the method is easy to operate, complex liquid phase treatment is not needed, and the stability of the generated hydroxyl under the subsequent high-temperature gas-solid phase hydrogen-rich reaction condition is obviously superior to that of hydroxyl introduced through a traditional method. The stable hydroxyl enriched on the surface serves as an effective Lewis base site and cooperates with a Ru active site, adsorption and activation of CO2 molecules are remarkably promoted, and therefore the catalytic activity of the CO2 methanation reaction is greatly improved.

A method for producing dihydrogen by photodissociation of water, may include bringing an aqueous solution in contact with oxidized nanodiamonds under solar, natural, or artificial illumination (or light). The oxidized nanodiamonds may have an oxygen / carbon ratio of at least 5% atomic, determined by XPS without previous treatment of the oxidized nanodiamonds. The method may further include preparing the oxidized nanodiamonds by subjecting nanodiamonds to an oxidizing treatment. The oxidizing treatment may include annealing at a temperature of 500° C.±50° C. for a duration in a range of from 1 to 5 hours under an oxygenated atmosphere.

Crumb rubber obtained from recycled tires is subjected to a process involving photodissociation to break a sulfur bond, sulfur-sulfur and / or sulfur-carbon bonds. The process utilizes a component that generates photonic energy upon being subjected to a compressing force (e.g., pressure). The photonic energy is bandwidth resonant with the sulfur-sulfur and / or sulfur-carbon bond, causing the bond to break apart. The resulting rubber is suitable for use in applications typically utilizing virgin rubber, such as new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

Methods for annotating product ions of a spectrum are disclosed. A product ion mass spectrum is received. Parameters indicative of producing a mass spectrum using a free radical induced dissociation method are received. At least one state of charge mass-to-charge ratio (m / z) adjustment is performed based on the parameter for at least one product ion peak of the mass spectrum and compared to one or more other product ion peaks of the mass spectrum. The at least one product ion peak is annotated based on the comparison. The state of charge adjustment includes loss of electrons or loss or acquisition of hydrogen atoms. The free radical induced dissociation method includes electron-based dissociation (ExD), ultraviolet light dissociation (UVPD), or infrared light dissociation (IRMPD).

A substrate has a photoresist film and an organic film. The photoresist film contains a first metal oxide and reacts to EUV (Extreme Ultra Violet) light. The organic film is formed under the photoresist film and contains a second metal oxide, the metal of which has a lower binding energy with oxygen than the metal of the first metal oxide that constitutes the photoresist film, and the second metal oxide dissociates oxygen by the EUV light.

A method of fabricating a peep-proof panel includes forming a first substrate structure including disposing a first composite adhesive layer structure and a first substrate on a first carrier plate, disposing a first anti-chemical layer on the first substrate and the first carrier plate, and forming a first light-transmitting conductive layer on the first anti-chemical layer; forming a second substrate structure, including disposing a second composite adhesive layer structure and a second substrate on a second carrier plate, disposing a second anti-chemical layer on the second substrate and the second carrier plate, and forming a second light-transmitting conductive layer on the second anti-chemical layer; and assembling the first substrate structure and the second substrate structure, carrying out irradiation dissociation treatment, and removing the second carrier plate and the second composite adhesive layer structure. After the irradiation dissociation treatment, the adhesive force of the second composite adhesive layer structure to the second carrier plate is greater than that of the second composite adhesive layer structure to the second substrate. The process steps of the peep-proof panel are simplified, so that the cost is reduced.
