Here we initiate the use of the HSAB, i.e., hard and soft (Lewis) acid and base, principle to explain the cycling stability difference among Cu-based frameworks and the difference between Cu-based and non-Cu-based frameworks in general in the hope to find directions to the development of...
What is true of a Lewis acid? What is h in physical chemistry? What is the Lewis structure for SO4 2-? What does NaHCO_3 do in organic chemistry? What is molar in chemistry? What is protonation in organic chemistry? What is industrial chemistry?
Al2(SO4)3·18H2O can play both Brønsted and Lewis acid roles in methanol and catalyze the conversion of monosaccharide to alkyl levulinates and levulinic acid. After pre-oxidation at optimized conditions, cellulose can be converted into methyl levulinate and levulinic acid over Al2(SO4)3 in...
