Abstract Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on reactions of graphite with mixed strong oxidants, which suffer from explosion risk, serious environmental pollution, long-reaction time up to hundreds hours. Here, we report a scalable, safe green method synthesize graphene high yield based water electrolytic oxidation graphite. The lattice fully...
Tin dioxide (SnO2) has been demonstrated as an effective electron-transporting layer (ETL) for attaining high-performance perovskite solar cells (PSCs). However, the numerous trap states in low-temperature solution processed SnO2 will reduce PSCs performance and result serious hysteresis.

Abstract 2D material‐based electronic devices like graphene–silicon photodetectors (Gr–Si PDs) have attracted much attention of researchers in the past few years. Due to nature Schottky junction, Gr–Si PDs ultrafast response. However, responsivity is very low, which hinders their practical application. Low work function Gr and poor absorbance Si are mainly responsible for this problem. Here, a novel approach coupling with fractal platinum nanoparticles (Pt NPs) demonstrated enhance speed up...
