Development of Inorganic Condensed Phosphate Catalysts for Decomposition of Global Warming Gas

Abstract

Aluminum and nickel ortho-and condensed phosphates were used as a catalyst for decomposition of trifluoromethane and nitrogen trifluoride. The specific surface area, acid strength, and amount of acidic sites of phosphates were also estimated. The condensation degree of phosphates, the addition of other metal cation, and the reforming by mechanical treatment were discussed on the catalytic activity of the phosphates for the design of catalyst.

CuFe2O4 and ZrP2O7 nanoparticles as highly efficient catalysts for the one-pot synthesis of phthalazine derivatives under solvent-free conditions

“…Nanoparticles reduce reaction times and they can be recovered from the reaction mixture using simple ltration [31][32]. Zirconium pyrophosphate (ZrP 2 O 7 ) is one of the greatly studied materials due to its useful contribution to various elds of application [33]. Pyrophosphate compounds, which contain zirconium, can reveal intensive luminescence at room temperature [34][35].…”
