Synthesis of delafossite CuCrO2 via solution combustion method and its acid functionalization for biodiesel production

“…In their investigation, 1% catalyst mass and 20:1 alcohol:oil molar ratio were employed in which 80% yield was obtained after 6 h of reaction at 100 °C. Yuan et al [32] developed acid-based carbon catalysts which are utilized in the transesterification of soybean oil. In this research, an 8:1 molar ratio of ethanol to oil, 7% of catalyst, and a reaction period of 8 h at 80 °C were employed.…”

Porous acid–base hybrid polymers for enhanced NH3 uptake with assistance from cooperative hydrogen bonds

“…It was found that the hydrogen bonding interactions between the ionic liquids (ILs) and NH 3 were the key to the signicant increase in NH 3 capacity according to Palomar's work. 23 Therefore, protic ILs 24,25 and ILs substituted with hydroxyl groups, 23,26 and poly ionic liquids (PILs) served as adsorbents of ammonia. 27,28 In our previous work, 29,30 amidine and pyridine-based protic ILs constructed with CHBs presented sigmodal isotherms, and the results indicated a high NH 3 capacity of 7.5-9.3 mmol g −1 at 1 bar, 30 °C; furthermore, the threshold pressure could be regulated through the CHBs.…”
