“…177–180 Monoprotic acids are typically employed as modulators to generate defects during the cultivation of Zr-MOFs. Some frequently employed monoprotic acid modulators for synthesizing defective Zr-MOFs are hydrochloric acid (HCl, p K a = −7.00), 181,182 and monocarboxylic acids such as formic acid (HFo, p K a = 3.77), 183,184 acetic acid (HAc, p K a = 4.76), 43,183,184 benzoic acid (BA, p K a = 4.20), 184 trifluoroacetic acid (TFA, p K a = 0.23), 34,185–188 amino acids (AAs), 189 dichloroacetic acid (DCA, p K a = 1.30), 154 trichloroacetic acid (TCA, p K a = 0.66), 190,191 difluoroacetic acid (DIF, p K a = 1.24), 34,192 mercaptoacetic acid/thioglycolic acid (MA, p K a = 3.83), 193,194 dodecanoic acid (DDA, p K a = 5.3), 195 and 2-thiophenecarboxylic acids (p K a = 3.49). 196 Surfactants such as cetyltrimethylammonium bromide (CTAB) can also induce the defects in Zr-MOFs.…”
