Abstract:
... Converting toxic air pollutants such as nitric oxide (NO) and carbon monoxide (CO) into less harmful gases remains a critical challenge for many industrial technologies. Here, by performing first-principles calculations, we introduce a cheap, stable and novel catalyst for the conversion of NO and CO molecules into N₂O and CO₂ using Al-doped MoS₂ (Al–MoS₂). According to our results, dissociation of ...

Subject:
catalysts; chemical bonding; density functional theory; dissociation; energy; heat production; nitric oxide; nitrogen; nitrous oxide; reaction mechanisms; temperature
Abstract:
... The reaction mechanism of nitric oxide (NO) reduction to nitrous oxide (N₂O) and N₂ catalyzed by a Cr-phthalocyanine sheet (CrPc) was investigated using periodic density functional theory (DFT). The results show that direct NO dissociation on the catalyst is inhibited by a large energy barrier owing to the difficulty of direct cleavage of the strong NO bond. The dimer mechanism in which two NO mol ...

Abstract:
... A one-dimensional energetic complex (Na[CL-14·2H₂O]) constructed from sodium and 5,7-diamino-4,6-dinitrobenzofuroxan (CL-14) was synthesized, and its crystal structure was analyzed by X-ray diffraction. The crystal belongs to a monoclinic system with space group P2₁/c. The complex possesses a one-dimensional coordination framework based on the [ONaN]ₙ chain, which might result in its low sensitivi ...

Subject:
air; atmospheric pressure; catalysts; engineering; heat production; nitric oxide; ovens; oxidation; oxygen; temperature; thermal degradation
Abstract:
... Temperature-programmed oxidation (TPO) experiments were used to evaluate the performance of uniformly (standard) and nonuniformly (zoned) distributed Pt/Al₂O₃ catalysts after homogeneous and heterogeneous thermal degradation. Both catalysts were homogeneously aged in an oven by exposing the entire catalyst to 750 °C in air for 4 h at atmospheric pressure. In heterogeneous aging, only the back of t ...

Abstract:
... A novel energetic green combustion catalyst, 1,8-dihydroxy-4,5-dinitroanthraquinone barium salt (DHDNEBa), was firstly synthesized by the process of metathesis reaction with a yield of 95.7%, and its structure and thermal behavior were characterized by IR, elemental analysis, thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC). The thermal decomposition kinetics and mechani ...
