SnO2/Sn with core–shell structure Schottky heterojunctions loaded in graphene to promote electrochemical reaction kinetics and enable efficient lithium-ion storage

Herein, to better construct homogeneous heterostructures, we synthesize Schottky heterojunction composites in situ , which utilize a three-dimensional porous graphene carbon material to form more SnO 2 /Sn/G heterointerfaces and oxygen vacancies.
