In this paper, we reported an effective and simple strategy to prepare large areal mass loading of MnO2 on porous graphene gel/Ni foam (denoted as MnO2/G-gel/NF) for supercapacitors (SCs). The MnO2/G-gel/NF (MnO2 mass: 13.6 mg cm−2) delivered a capacitance 3.18 F cm−2 (234.2 g−1) good rate capability. prominent electrochemical properties are attributed the enhanced conductivities improved accessible area ions in electrolytes. Moreover, asymmetric supercapacitor (ASC) based 6.1 positive...
High-temperature activation has been commonly used to boost the photoelectrochemical (PEC) performance of hematite nanowires for water oxidation, by inducing Sn diffusion from fluorine-doped tin oxide (FTO) substrate into hematite. Yet, thermally annealed at high temperature suffer two major drawbacks that negatively affect their performance. First, structural deformation reduces light absorption capability nanowire. Second, this "passive" doping method leads nonuniform distribution dopant...
