Abstract

Back cover image: It is common expectation that decreasing particle size (like thickness) can enhance the activities of catalysts due to geometric and electronic alternations (known as the “catalyst size effect”). However, there are exceptions. In article number CNL266, we have fabricated two metal-organic frameworks (MOFs) sample with different thickness (134.846 and 1.97 nm). In contrast to common expectations, large-thickness MOF has exhibited superior carbon dioxide electroreduction activities as comparison to small-thickness counterpart. Further explanations have been studied systematically by using density function theory (DFT) calculations. The results of this work have challenged the common concept, which would provide new clues for catalyst design toward a number of electrochemical systems.
