A highly negatively charged borotungstic acid H5BW12O40 had been tested as homogeneous catalyst in esterification. Compared with common used H3PW12O40, it displayed a higher conversion (98.7%) and excellent efficiency (96.2%) due to its high amount of protons in methanol. In order to overcome th...detailed
Proton-conducting polymer electrolytes consisting of borotungstic acid (BWA) and polyacrylamide (PAM) were developed. The addition of BWA to PAM progressively improved the electrolyte conductivity. The as-fabricated BWA-PAM electrolyte exhibited a high ionic conductivity of ca. 27 mS cm−1, but s...detailed
