摘要:Disclosed are a catalyst for synthesis of methanol from synthesis gas and a method for preparing the same. The catalyst includes a Cu—Zn—Al oxide containing CuO, ZnO and Al 2 O 3 in a predetermined ratio or Cu—Zn—Al—Zr oxide containing CuO, ZnO, Al 2 O 3 and ZrO 2 in a predetermined ratio, in combination with a cerium-zirconium oxide obtained by a sol-gel process. As compared to the existing Cu—Zn—Al catalysts for synthesizing methanol, the catalyst disclosed herein inhibits formation of byproducts and improves yield of methanol. Therefore, it is possible to improve methanol purification efficiency and carbon conversion efficiency.

摘要:Some embodiments include a method of preparing a phototuned metal-organic framework by forming a first solution by dissolving ZrOCl 2 .8H 2 O in dimethylformamide (DMF) and formic acid, mixing and dissolving 1,4-phenylenediacrylic acid in a second solution of dimethylformamide (DMF) and trimethylamine, and at least partially mixing the first and second solutions to form a mixture. The method further includes sealing the mixture in an autoclave and heating the mixture to above ambient temperature for a specified period of time to prepare ZrPDA metal-organic framework, and extracting the ZrPDA metal-organic framework and at least partially reacting to a specified degree at least some of ZrPDA metal-organic framework through [2+2] cycloaddition reactions. The specified degree can be tunable based at least in part on at least one of the intensity of UV radiation, the exposure time, and the UV wavelength.

摘要:Disclosed is a method for methanol synthesis using synthesis gas obtained from reforming of natural gas with carbon dioxide. First, synthesis gas is obtained from steam carbon dioxide reforming of methane, in which steam reforming of natural gas is carried out simultaneously with carbon dioxide reforming of methane, by using a catalyst (Ni/Ce/MgAlO x , or Ni/Ce—Zr/MgAlO x ) and processing condition capable of maintaining a predetermined ratio of carbon monoxide, carbon dioxide, and hydrogen [H 2 /(2CO+3CO 2 )=0.85-1.15]. Next, methanol synthesis is carried out by using the obtained synthesis gas and a catalyst system suitable for methanol synthesis with minimum byproduct formation (a catalyst system including a Cu—Zn—Al oxide containing CuO, ZnO, and Al 2 O 3 at a predetermined ratio in combination with a cerium-zirconium oxide obtained by a sol-gel process). In addition, unreacted synthesis gas remaining after the operation of methanol synthesis is recycled efficiently to improve the carbon availability (methane and CO 2 availability) and energy efficiency in the overall process.

摘要:The present invention provides use of an ionization radiation source in preparation of a porous crystalline material, and a method for preparing a MOFs material and a COFs material. In the present invention, the ionization radiation source is used for preparing the porous crystalline material; under the irradiation of the ionization radiation source, the porous crystalline material (MOFs, COFs) can be synthesized in an extremely short time, wherein the ionization radiation source is used for providing energy required in a reaction for preparing the porous crystalline material. The preparation process does not need heating, so that energy consumption is reduced and a high-pressure system is avoided. The aforementioned preparation method is simple, low in instrument and equipment cost, and thus is a environmentally friendly and extremely low-cost synthesis method.

摘要:A radiation shielding material for shielding against gamma radiation includes neodymium-doped zirconia nanoparticles in a matrix. The neodymium doped zirconia nanoparticles have a tetragonal crystal structure and an average size between about 25 nm to about 35 nm. The nanoparticles have a neodymium content in the range of about 1.5 mol % to about 3 mol % based on the total molar content of the zirconia nanoparticles. A method for the synthesis of neodymium-doped zirconia nanoparticles is provided. The method includes controlled metamorphosis of zirconia from monoclinic to tetragonal phase which results in a multifunctional shielding material having durability and high radiation absorption efficiency.
