Formaldehyde has been widely observed in the icy mantle of interstellar grains. H 2 CO may be formed from successive hydrogenations and further contribute to chemical complexity Interstellar medium (ISM) participating heterogeneous reactions with colliding gas phase atoms. Within this context, Eley-Rideal Langmuir-Hinshelwood rate constants formation on a formaldehyde doped amorphous water ice ...

Self-metalation is a promising route to include single metal atom in tetrapyrrolic macrocycle organic frameworks supported by surfaces. The molecule–surface interaction may provide the charge transfer and geometric distortion of molecular plane necessary for inclusion. However, at surface presence an activation barrier can represent obstacle that cannot be compensated higher substrate temperatu...

The Friedel-Crafts acylation of furan to produce 2-acyl by using acetic anhydride is industrially important but it uses highly polluting liquid acids as catalysts. In this study, supported modified heteropoly were used heterogeneous catalysts in a solventless green process. Metal exchanged dodecatungstophosphoric acid (DTP) was loaded on three different supports, and its effect evaluated. 20% w...

Manganese oxides (MnOx) have attracted particular attention in the selective catalytic reduction of NOx with NH3 (NH3-SCR) because their excellent low-temperature activity. Herein, we prepared a highly efficient MnO2 (MnO2-M) catalyst through facile ball milling-assisted redox strategy. MnO2-M shows 90% conversion wide operating temperature window 75–200 °C under gas hourly space velocity 40,00...
