Graphene-loaded porous ZnCo2O4 nanosheets composite (ZnCo2O4/RGO) had been synthesized by annealing the precursors, which were obtained after a simple hydrothermal method. Scanning electron microscope (SEM) and transmission electron microscopy (TEM) images revealed the microstructure of as-synthesized products. Raman spectroscopy confirmed the existence of RGO in the composite. ZnCo2O4/RGO composite...
SnO2@RGO nanoparticles were successfully fabricated via a one-step solvothermal technique and used as an alternative to Pt counter electrode (CE) in dye-sensitized solar cells (DSSC). The SnO2 nanoparticles were dispersed on graphene sheets uniformly, forming a nanoscale composite system. The electrochemical performance analysis indicated that the SnO2@RGO electrode exhibited remarkable electrocatalytic...
