Summary: The study demonstrated the challenge of protecting Cu2O nanowire from photocorrosion using annealed rGO. It was found that rGO failed to provide a conformal passivation around Cu2O NW, leading to dramatic photocorrosion. A proposed solution was the use of sputtering technique for carbon coating, considered as the ideal protection strategy.

Summary: In this study, composite thin films of binary metal chalcogenides (CdxZn1-xS) and electrochemically reduced graphene oxide (RGO) were successfully fabricated via repetitive cyclic voltammetry. The incorporation of RGO enhanced the conductivity and prevented photocorrosion of the chalcogenides, leading to an increase in photocurrent density. The optimized composition of CdxZn1-xS and RGO composites showed significantly enhanced photoelectrochemical performance under solar light irradiation.

Summary: The deposition of reduced graphene oxide layer on SnS thin films has been shown to improve their photoelectrochemical response, enhancing the photocurrent density and photostability while promoting charge carrier separation at the interface. The rGO layer acts as a protective layer for SnS in the electrolyte and serves as an electron reservoir to accept photoexcited electrons, highlighting its promising role in enhancing photoelectrochemical water splitting.

Summary: This study demonstrates the use of the layer-by-layer (LbL) assembly technique to create wire-shaped supercapacitors (WSCs) with enhanced capacitance, energy density, and power density. The WSCs consist of alternating layers of positively charged reduced graphene oxide functionalized with poly(diallyldimethylammonium chloride) and negatively charged Ti3C2Tx MXene nanosheets conformally deposited on activated carbon yarns. The LbL coatings on carbon yarns show promise as linear energy storage devices for fibrous electronics.

Summary: Perovskite photovoltaics have emerged as a promising technology for next-generation photovoltaics. Developing a hole blocking layer (HBL) has proven to be a successful method in improving the efficiency of perovskite solar cells (PSCs). In this study, planar 3D/2D devices were developed using tin oxide (SnO2) modified with reduced graphene oxide (rGO). The modified HBL showed improvements in perovskite crystallization, optical absorption, and defect passivation at the perovskite/SnO2 interface, resulting in enhanced charge transfer and better work function alignment. The incorporation of optimized 3% rGO additive in the SnO2 layer led to champion performance in Jsc, Voc, and FF of the PSCs, with an efficiency boost from 16.48% to 20.98%. This HBL modification approach allows for defect passivation, further improving the performance of perovskite photovoltaics.

Summary: Solid oxide fuel cells (SOFCs) are efficient electrochemical devices that convert the chemical energy of a fuel directly into heat and electrical energy. The electrochemical performance of SOFCs is greatly affected by the materials and microstructure of the electrodes, particularly at the triple phase boundaries (TPBs) within the electrodes. This study investigates the addition of reduced graphene oxide (rGO) to the cathode functional layer (CFL) to improve cell performance by utilizing the high electrical properties of graphene. Experimental results show a significant increase in peak performance for cells coated with a single layer of CFL containing 1 wt % graphene and sintered at 1050 degrees C, compared to the reference cell.
