Bifunctional acid−base catalysts are highly desirable for industrially relevant chemical processes. Owing to their ability to activate electrophiles and nucleophiles simultaneously, they allow the ...
Structural characterizations for the as-prepared catalysts. (a) XRD patterns of the Co3O4 and 4% Er−Co3O4. (b) Crystal structure of the Co3O4 in this study. (c) TEM image of 4% Er− Co3O4, (d-e) HRTEM ...
New findings reveal that organosulfate groups, not carboxyls, control graphene oxide's surface charge in water, challenging long-standing models and reshaping its chemical profile. (Nanowerk Spotlight ...
