Self‐Assembled LaFeO3/ZnFe2O4/La2O3 Ultracompact Hybrids with Enhanced Piezo‐Phototronic Effect for Oxygen Activation in Ambient Conditions

“…The electron transfer number ( n ) was determined according to the following equation: [ 1,34 ] $$\[ \begin{array}{*{20}{c}}{n = \frac{{{I_d}}}{{\frac{{{I_d} + {I_r}}}{N}}}100\\end{array} \]$$The H 2 O 2 selectivity was calculated according to the following equation: $$\[ \begin{array}{*{20}{c}}{{{\rm{H}}_2}{{\rm{O}}_2}\left( \\end{array} \]$$where I r is the ring current, I d is the disk current, and N is the collection efficiency ( N = 0.37) of the RRDE.…”

“…The improved surface OV concentration is conducive for catalysis as it often serves as an active site to promote the adsorption and activation of oxygen molecules. [34] Furthermore, the improved surface OV content would remarkably affect the material physicochemical properties such as the free electron density and electronic configuration, which might be other beneficial factors for catalysis. [35] Adv.…”

A carbon dot-based metal-free photocatalyst enables O2 to serve as both a reactant and electron sink for enhancing H2O2 photoproduction

“…[1][2][3][4] The process of photocatalysis is simple and convenient, which involves dispersing a photocatalyst in water and then yielding a product under light, which has good prospect for industrialization. 5,6 Hydrogen peroxide (H 2 O 2 ), as an alternative clean oxidant material, [7][8][9][10] has the advantages of convenient transportation and higher energy density than hydrogen, exhibiting wide application in synthesis, industry and other elds. [11][12][13][14][15] However, the major method for the synthesis of H 2 O 2 at present is anthraquinone oxidation, which has high energy consumption and the risk of explosion.…”
