Bifunctional Catalysts for CO₂ Reduction and O₂ Evolution: A Pivotal for Aqueous Rechargeable Zn−CO₂ Batteries

Divyani Gupta, Jianfeng Mao, Zaiping Guo

Advanced Materials > 36 > 35 > n/a - n/a

The quest for the advancement of green energy storage technologies and reduction of carbon footprint is determinedly rising toward carbon neutrality. Aqueous rechargeable Zn–CO₂ batteries (ARZCBs) hold the great potential to encounter both the targets simultaneously, i.e., green energy storage and CO₂ conversion to value‐added chemicals/fuels. The major descriptor of ARZCBs efficiency is allied with...

BaMnO3 nanostructures: Simple ultrasonic fabrication and novel catalytic agent toward oxygen evolution of water splitting reaction

Sousan Gholamrezaei, Mojgan Ghanbari, Omid Amiri, Masoud Salavati-Niasari, more

Ultrasonics Sonochemistry > 2020 > 61 > C

In the current paper, the main aim is to fabricate the BaMnO ₃ nanostructures via the sonochemical route. The various factor, including precursors, reaction time and power of sonication can affect the shape, size, and purity of the samples. We utilized X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR),...

Sonochemical synthesis of SrMnO3 nanoparticles as an efficient and new catalyst for O2 evolution from water splitting reaction

Sousan Gholamrezaei, Masoud Salavati-Niasari

Ultrasonics Sonochemistry > 2018 > 40 > PA > 651-663

The principal focus of this investigation is to prepare the SrMnO₃ nanostructures by different chemical methods such as ultrasonic, co-precipitation, microwave, and hydrothermal methods. The influence of calcination temperature, and ultrasound irradiation power, and the presence of surfactant investigated on morphology and size of SrMnO₃ nanostructures. As-prepared nanoparticles were characterized...

Oxygen reduction and evolution in an ionic liquid ([BMP][TFSA]) based electrolyte: A model study of the cathode reactions in Mg-air batteries

Y.T. Law, J. Schnaidt, S. Brimaud, R.J. Behm

Journal of Power Sources > 2016 > 333 > C > 173-183

Aiming at a molecular scale understanding of the cathode processes in an Mg-air battery, we have investigated the oxygen reduction (ORR) and oxygen evolution (OER) reactions under well-defined conditions, using an ionic liquid (butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)amide, [BMP][TFSA]) based electrolyte and polycrystalline Au and glassy carbon, respectively, as model electrodes....
