Size- and shape-dependent catalytic performances of oxidation and reduction reactions on nanocatalysts

Abstract

Heterogeneous catalysis is one of the most important chemical processes of various industries performed on catalyst nanoparticles with different sizes or/and shapes. In the past two decades, the catalytic performances of different catalytic reactions on nanoparticles of metals and oxides with well controlled sizes or shapes have been extensively studied thanks to the spectacular advances in syntheses of nanomaterials of metals and oxides. This review discussed the size and shape effects of catalyst particles on catalytic activity and selectivity of reactions performed at solid-gas or solid-liquid interfaces with a purpose of establishing correlations of size- and shape-dependent chemical and structural factors of surface of a catalyst with the corresponding catalytic performances toward understanding of catalysis at a molecular level.

Novel amperometric glucose biosensor based on MXene nanocomposite

“…With decreasing size of a metal nanoparticle, the effect of atoms at corners and edges of nanoparticles becomes dominant which exhibit intrinsically different catalytic performance in contrast to a nanoparticle with a larger size48. Similarly, materials with different shapes (flowers, sheets) usually exhibit quite different catalytic behaviors intrinsically resulting from the differences in geometric structure and electronic state of the catalyst atoms associated with different crystallographic surfaces49.

CO2 Reduction: From the Electrochemical to Photochemical Approach

“…(1) Nanostructuring : Nanostructuring so far is the most common and popular approach to promote the performance of catalyst materials 111, 112. When the size of catalyst particles is reduced down to the nanoscale, their surface areas are dramatically enhanced, which more than often leads to heightened activities.…”

Electrocatalysis on shape-controlled metal nanoparticles: Progress in surface cleaning methodologies

“…Currently, the most relevant advances in this field appear now included in interesting reviews about the use of these shaped metal nanoparticles for many different electrocatalytic applications [3][4][5][6][7][8][9][10][11][12]. Interestingly, all these studies This is a previous version of the article published in Current Opinion in Electrochemistry.…”
