摘要:The present invention concerns the synthesis of the salts of a Triazolium N-Heterocyclic Carbene (NHC) catalyst in various salt forms prepared from 2-methylaniline, 2-methylphenylhydrazine hydrochloride or 2-methylphenylhydrazine. The molecules so prepared are useful in catalysis of carbene reactions and are advantageous due to their lack of chlorinated or fluorinated intermediates and lack of chlorine or fluorine in the final structure.

摘要:Disclosed is a method for rapidly preparing a mica-supported carbon nitride photocatalytic material by means of microwaves, wherein the mica-supported carbon nitride photocatalytic material is prepared by coating the surface of a two-dimensional flaky mica as a support with a layer of microwave-absorbing material, i.e., stannic oxide, and subjecting same to a microwave method with an amino compound as a material for the synthesis of a graphite-like carbon nitride. Stannic oxide has a very good microwave-absorbing property. By mixing same with the amino compound and by means of the microwave effect heating from outside in, the depth of the microwave action is expanded, the efficiency and uniformity of the microwave synthesis of the mica-supported carbon nitride are improved, the preparation time is reduced, the usage amount of the external microwave medium is greatly reduced, and resources are saved.

摘要:The present invention relates to a process for producing a hybrid TiO2 material doped with carbon quantum dots, useful for producing photoelectrodes to be incorporated into thin-film solar cells. The process comprises: (a) synthesis of the hybrid material, which in turn comprises 3 sub-steps: (a.1) feeding: the following must be added to a reactor in the following order: a solvent, a carbon precursor, and finally titanium isopropoxide, the reactor operating at between 160 and 200°C for a period of between 14 and 18 hours; (a.2) filtering and washing of solids: the obtained solids must be filtered and washed, and the solids must be dried at 80 - 120°C for at least 2 hours; scaling of the feeding was verified at a factor of up to 50 times greater; and (a.3) calcination: the product obtained in step (a.2) must be calcinated at between 300 and 400°C, or 500 and 600°C; and (b) synthesis of the photoelectrode based on TiO2 doped with carbon in the form of thin films: the TiO2 doped with carbon (having an atomic ratio equal to 99:1) is dispersed in a mixture of terpineol and ethyl cellulose having a percentage ratio of 94:6 in excess acetone, constantly stirring for 48 – 72 hours; subsequently, once the layer of hybrid material is deposited on the tin oxide-based electrode doped with fluorine, the acetone is left to evaporate, and it is sintered to remove the terpineol and ethyl cellulose.

摘要:The present invention generally relates to a process of fabricating an asymmetric supercapacitors device comprising synthesizing a BaO and CeO 2 thin film as a first electrode using a one-step successive ionic layer adsorption and reaction (SILAR) method for uniform deposition and adhesion on a conductive substrate; synthesizing an activated carbon (AC) electrode as a second electrode; formulating a solid-state electrolyte layer comprising polyvinyl alcohol (PVA) and potassium hydroxide (KOH), wherein the solid-state electrolyte layer is formed as a gel; assembling the device by layering the first electrode, the solid-state electrolyte layer, and the second electrode in a stacked configuration, wherein the assembled device is allowed to stabilize for a period of 12-24 hours at room temperature to ensure uniform distribution of the electrolyte and structural integrity; and pressing the assembled layers together to enhance contact between electrodes and the electrolyte.
