Designed synthesis of hierarchical Mn3O4@SnO2/Co3O4 core-shell nanocomposite for efficient electrocatalytic water splitting

Water electrolysis: from textbook knowledge to the latest scientific strategies and industrial developments

“…There are however several contributions that report on SnO 2 -based composite materials or doped -SnO 2 for application in water electrolysis. 550,[555][556][557][558][559] For instance, Sreekanth et al 559 recently described the synthesis and investigation of SnO 2 quantum dots decorated on spinel cobalt ferrite nanoparticles to give SnO 2 QDs@CoFe 2 O 4 NPs nanocomposites. In combination with Ni foam, this composite gave an averageactive water electrolysis anode for alkaline OER (Z = 290 mV; j = 10 mA cm À2 ; 1.0 M KOH).…”

“…Song et al synthesized the hierarchical nanocomposite core–shell Mn 3 O 4 @SnO 2 /Co 3 O 4 successfully through a facile infrastructural construction approach (Figure a) . The SnO 2 /Co 3 O 4 composite nanosheets were encircled on the Mn 3 O 4 nanorod surface.…”

Recent insights into SnO2-based engineered nanoparticles for sustainable H2generation and remediation of pesticides

“…15b and d) demonstrate the Mn 3 O 4 @SnO 2 /Co 3 O 4 nanoshell. 143 Bao et al reported the fabrication of flower-like SnO 2 with g-C 3 N 4 via the hydrothermal method to enhance the photocatalytic activity. The flower-like SnO 2 uniformly grow on the surface of the layer structured g-C 3 N 4 , which enhanced the surface area of the nanocomposite (Fig.…”
