摘要： A ceramic-based composite material used for low-concentration formaldehyde degradation, and preparation method therefor belonging to the technical field of environmental engineering. The present invention comprises: utilizing an alkali metal-transition metal (i.e. A-T) alcohol solution mixed at low temperature with a TiO2 sol to obtain an A-T-TiO2 sol; immersing activated ceramic (HFC) into the A-T-TiO2 sol, and stirring at normal temperature to obtain A-T-TiO2/HFC; subjecting the obtained A-T-TiO2/HFC to primary drying and primary low-temperature calcination to form A-T-TiO2/FC; then immersing the A-T-TiO2/FC into a metal-organic framework (MOF)-amino silane sol to obtain an aminated A-T-TiO2/MOF/NFC precursor; and finally, subjecting the obtained precursor to secondary drying and secondary low-temperature calcination, forming an A-T-TiO2/MOF/NFC composite material. The present invention effectively degrades low-concentration formaldehyde in indoor environments or in air. Loading MOF on an aminated ceramic and doping alkali metal significantly improve the formaldehyde enrichment and degradation performance of the composite material, which is beneficial to the thorough removal of low-concentration formaldehyde in indoor environments or in air.

摘要： Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al2O3 having a specific surface area of 5 m2/g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al2O3; and a third step for performing a reduction process on the 12CaO·7Al2O3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.

摘要： Disclosed are ruthenium-based catalyst systems, hafnium-based catalyst systems, and yttrium-based catalyst systems for use in ammonia decomposition. Catalyst systems include ruthenium, hafnium, and/or yttrium optionally in combination with one or more additional metals that can be catalytic or catalyst promoters. Hafnium-based and yttrium-based catalyst systems can be free of ruthenium. The catalyst systems also include a support material. Disclosed catalyst systems can decompose ammonia at relatively low temperatures and can provide an efficient and cost-effective route to utilization of ammonia as a carbon-free hydrogen storage and generation material.

摘要： The present invention relates to a dehydrogenation catalyst in which a platinum-group metal, an assistant metal, and an alkali metal or alkaline earth metal component are supported on a carrier, wherein the molar ratio of platinum to the assistant metal is 0.5 to 1.49, and the catalyst has an acidity amount of 20 to 150 μmol KOH/g catalyst when it is titrated with KOH. The dehydrogenation catalyst according to the present invention may prevent coke formation from increasing rapidly when the hydrogen/hydrocarbon ratio in a dehydrogenation reaction is reduced, thereby increasing the productivity of the process. Accordingly, it makes it possible to operate the process under a condition in which the hydrogen/hydrocarbon ratio in a dehydrogenation reaction is reduced, thereby improving the economy of the process.
