Solution combustion synthesis is proposed to fabricate spongy ceria by using two different fuels for combustion: glycine and urea. As-prepared samples are labeled as SCOGl and SCOUr The acid-base properties of the cavities and surfaces of specimens are determined by measuring the pH of zero charges. Both SCOGl and SCOUr powders are decorated by the...

A superior NADH sensing platform was constructed based on porous PtAg nanoshells supported on reduced graphene oxide (PtAg/rGO) in the absence of any enzymes and redox mediators. The PtAg/rGO composite was prepared via one-step reduction combined with galvanic replacement reaction. The as-made PtAg/rGO assembles multiple structural advantages of co...

AbstractThe use of hydrogen as a green fuel alongside an environmentally friendly electrolyte is the most promising technology required for the conversion and storage of renewable energies and the transition to a low carbon future. Nanocrystalline Ni–Cu alloys have been electroplated onto copper electrodes and characterized via scanning electron mi...

Transition metal phosphides (TMPs) have recently emerged as promising hydrogen evolution reaction (HER) catalytic alternatives to platinum. Among them, molybdenum phosphide (MoP) has attracted extensive attention due to its high electrical conductivity, good stability, and Pt-like electronic structure; however, there is no systematic comparison of ...

Graphitic carbon nitrides supported cuprous oxide architecture is reported as an efficient electrode material for supercapacitors, especially due to its high charge-transfer conductivity of the electrochemical devices. Herein, we present an electrochemical sensor to specifically detect 8-hydroxy-2′-deoxyguanosine (8-HDG) oxidative stress biomarker ...

The synthesis of hierarchical NiCo2O4-CoNiO2 hybrids embedded in partially reduced graphene oxide (represented by NiCo2O4/[email protected]) is described. They were derived from ultrathin CoNi-based zeolitic imidazolate framework (CoNi-ZIF) nanosheets vertically grew on three-dimensional (3D) pRGO networks by pyrolysis at different temperatures (300, 60...

AbstractBinary metallic sponges comprising of nickel–cobalt (NiCo) hydroxide/oxide composites are prepared using a simple pyrolysis method by employing cyanocobalamin as a new sacrificial template. Subsequently these highly porous materials are demonstrated as an efficient electrocatalyst for oxygen evolution reaction (OER) under alkaline condition...

Based on the intrinsic electrochemical features of brucine integrated with carbon nanotubes (brucine/SWNTs), dimeric quinoid brucine was electrochemically generated by electroactivation of a brucine/SWNTs-modified GC electrode and used as a novel electrocatalyst for efficient electro-oxidation of hydroxylamine (HA). The electrocatalytic activity wa...
