Eco-Friendly Approach for Graphene Oxide Synthesis by Modified Hummers Method by Néstor Méndez-Lozano, Francisco Pérez-Reynoso, Carlos González-Gutiérrez

“…The XRD results show that the space between the layers of GO60 is slightly larger than that for GO90. SEM images show a homogeneous network of graphene oxide layers of ≈6 to ≈9 nm. …”

Quantum capacitances of transition metal-oxides (CoO, CuO, NiO, and ZnO) doped graphene oxide nanosheet: Insight from DFT computation by Idongesit J. Mbonu, Ernest E. Ekereke, Terkumbur E. Gber, Cookey Iyen, Ismail Hossain, Godwin O. Egah, Ernest C. Agwamba, Adedapo S. Adeyinka, Hitler Louis

“…From the quantum capacitance studies, it was observed that the value of CQ for graphene oxide (GO) increased slightly from 72.276 µF/cm2 to ZnO@GO (121.550 µF/cm2) > NiO@GO (93.870 µF/cm2) > CoO@GO (90.52 µF/cm2) > CuO@GO (89.375 µF/cm2). The results obtained herein can provide an effective and simple new idea for the design of graphene-based supercapacitors that possess high energy density.…”

Synthesis of Bi-Metallic-Sulphides/MOF-5@graphene Oxide Nanocomposites for the Removal of Hazardous Moxifloxacin by Aqsa Anum, Muhammad Altaf Nazir, Sobhy M. Ibrahim, Syed Shoaib Ahmad Shah, Asif A. Tahir, Misbah Malik, Muhammad Ahmad Wattoo, Aziz ur Rehman

“…This led to a narrow energy band gap (2.06 eV in Ni/Mo.S₂/MOF-5/GO, compared to 2.30 eV in Ni/Mo.S₂/MOF-5), as well as excellent photocatalytic activity in the photodegradation of moxifloxacin (MOX), listed in order: Ni/Mo.S₂/MOF-5/GO (95%) > Ni.S₂/MOF-5/GO (93%) > Mo.S₂/MOF5/GO (90%) > Ni/Mo.S₂/MOF-5 (86%) in concentrations up to 2.0 mgL⁻¹, caused by the production of superoxide (O₂^•−) and hydroxide (OH^•) radicals, which encouraged the effective photocatalytic activities of the heterostructure. …”

Effect of Nano-Graphene Oxide and n-Butanol Fuel Additives Blended with Diesel—<i>Nigella sativa</i> Biodiesel Fuel Emulsion on Diesel Engine Characteristics by Hurmathulla Khan, Manzoore Elahi M. Soudagar, Rajagopal Harish Kumar, Mohammad Reza Safaei, Muhammad Farooq, Abdulqhadar Khidmatgar, Nagaraj R Banapurmath, Rizwan A. Farade, Muhammad Mujtaba Abbas, Asif Afzal, Waqar Ahmed, Marjan Goodarzi, Syed Noeman Taqui

“…The nanofuel blend NSME25B10GO90 displayed an enhancement in the brake thermal efficiency (BTE) and a reduction in brake-specific fuel consumption (BSFC) at maximum load due to high catalytic activity and the enhanced microexplosion phenomenon developed by graphene oxide nanoparticles. …”
