A comparative study of hydrogen evolution in devices based on cadmium chalcogenides quantum dots (CdS, CdSe and CdTe) and its combinations, sensitizing TiO2 was carried out. A maximum photocurrent of 2.7 mA cm−2 at 0 V bias, and a solar-to-hydrogen (STH) conversion efficiency of 0.9%, was obtained with CdSe QDs due to its wide absorption range. The...

AbstractWe report the development of novel modes of operation for electrochemical disinfection of E. coli in human urine simulant with an aim to minimize the energy required for disinfection. The system employs boron-doped diamond electrodes and will be part of an energy neutral, water and additive free outdoor toilet being developed for use in dev...

Conducting electroactive polymers are promising candidates for next-generation sodium-ion batteries due to their environmentally benign properties, high stability, and low cost. In this work, polyaniline (PANI) nanofibers have been successfully prepared by interfacial polymerization and characterized using Fourier transform infrared (FTIR) spectros...

In this paper, a mediator-free scanning electrochemical microscopy (SECM) imaging concept is presented, which is capable of generating high electrochemical contrast and high spatial resolution between two conductive materials. The methodical approach is based on the hydrogen evolution reaction which shows potential dependent material selectivity. V...

Lithium manganese silicate (Li2MnSiO4) demonstrates rich polymorphism with orthorhombic Pmn21 polymorph having better crystalline ordering over orthorhombic Pmnb and monoclinic forms. In this work, Li2MnSiO4 nanoparticles with the Pmn21 phase were synthesized by hydrothermal synthesis. Powder X-ray diffraction, HRSEM, and HRTEM as well as SAXS inve...

In this work, we prepared reduced graphene oxide-supported PtCo nanospheres (PtCo/rGO) by a facile one-step hydrothermal method with the assistance of l-proline as the shape-directing agent. We systematically investigated the effects of various experimental conditions on the morphology and structure of the as-prepared PtCo/rGO hybrids. Compared wit...

Graphene nanoplatelet (GnP), which consists of small stacks of graphene, is used as a reinforcement to enhance the performance of the poly(acrylonitrile-butyl acrylate) (PANBA) binder in a lithium ion battery (LIB). To the best of our knowledge, this is the first time that a conductive nanofiller such as GnP has been used in a conventional water-di...

A series of four electrolytic reduction runs was performed in molten salt at bench scale to compare the performance characteristics of monolithic platinum and iridium as oxygen-evolving anodes, while simultaneously reducing uranium oxide to metal. In each run, 25 g of uranium oxide particulate was loaded into a permeable steel basket, which, in tur...

In this work, a glassy carbon electrode modified with graphene quantum dots and gold nanoparticles (GCE/GQDs/AuNPs) was developed for norepinephrine (NE) determination using squarewave stripping voltammetry. GQDs were synthesized by citric acid pyrolysis and characterized by UV–Vis and fluorescence spectroscopy. The chemically synthesized AuNPs wer...
