Figure 7.12. PXRD patterns of the materials obtained from different solvents with a small amount
of acetic acid or without acetic acid as component in the solvent mixture at the same conditions
(160 °C, 72h, solvothermal, starting with SBU-a and H 3 BTC) in comparison with SBU-a and Ru-
MOF 1. a) 4 ml diglyme and 4 drops HCl, b) 4 ml H 2 O and 0.7 ml HCOOH, c) 4 ml H 2 O and 0.7 ml
CF 3 COOH, d) 4 ml diglyme, e) 4 ml H 2 O and 4 drops HCl; f) pH = 1.89 solution of H 2 O and CF 3 COOH,
10 ml (note: the same pH value with the literature; [82] formula: 4ml H 2 O and 0.7ml CH 3 COOH); g)
pH = 1.89 solution of H 2 O and CF 3 COOH, 24 ml; h) pH = 1.89 solution of H 2 O and CF 3 COOH, 4.7 ml;
i) pH = 1.89 solution of H 2 O and HCl, 4.7 ml; j). 12 ml H 2 O and 161 μl CH 3 COOH (pH = 2.47; note
the same pH value with the literature [83] formula: 12ml H 2 O and 161 μl CH 3 COOH). Note: CF 3 COOH
was employed to trace the incorporation of the carboxylic acid by the CF 3 -group.
