Negatively Charged Boron Nitride Nanosheet as a Potential Metal-Free Electrocatalyst for Oxygen Reduction Reaction: a Computational Study

26-Jun-2018 | Xin Wen; Yongcheng Wang; Jing-Xiang Zhao, New Journal of Chemistry, 2018

The high cost and poor stability in an electrochemical environment, the conventionally employed Pt–based catalysts for oxygen reduction reaction (ORR) have hindered the large–scale commercialization of fuel cells. Thus, searching for the high activity, low–cost, and stable metal–free catalysts to ...

On the stability in alkaline conditions and electrochemical performance of A2BO4-type cathodes for liquid fuel cells

26-Jun-2018 | David Cardoso; Biljana Šljukić; Nuno Sousa; Cesar AC Sequeira; Filipe M Figueiredo; Diogo M.F. Santos, Physical Chemistry Chemical Physics, 2018

Typical direct liquid fuel cells (DLFCs) use a liquid fuel and O2 as the oxidant. However, for applications where O2 is not available (e.g., space and underwater), the gas has been replaced by H2O2 as a liquid oxidant. This work presents a study of various ceramic disc electrodes with K2NiO4 ...

A Highly Active, CO2-tolerant Electrode for Oxygen Reduction Reaction

20-Jun-2018 | Yu Chen; Seonyoung Yoo; yongman Choi; Jun Hyuk Kim; Yong Ding; Kai Pei; Ryan Murphy; Yanxiang Zhang; Bote Zhao; Weil ..., Energy & Environmental Science, 2018

One challenge facing the development of high-performance cathode for solid oxide fuel cells (SOFC) is the fast degradation rate of cathodes due to poisoning of contaminants commonly encountered in ambient air such as CO2. Here we report a double perovskite PrBa0.8Ca0.2Co2O5+δ (PBCC) cathode with ...

Size structure–catalytic performance correlation of supported Ni/MCF-17 catalysts for COx-free hydrogen production

20-Jun-2018 | Yanping Li; Jie Wen; Arshid M. Ali; Ming Duan; Wei Zhu; Hui Zhang; Chen Chen; Yadong Li, Chemical Communication, 2018

Herein, supported Ni/MCF-17 catalysts with the size of nickel nanocrystal in the range of 1.5–8.0 nm were synthesized and employed for COx-free hydrogen production for fuel cells via the ammonia decomposition reaction. Characterized by a variety of techniques, the results show that nickel ...

The reactivity of water and OH on Pt–Ni(111) films

12-Jun-2018 | F. McBride; A. Hodgson, Physical Chemistry Chemical Physics, 2018

Bimetallic Pt catalysts are of interest as water redox catalysts in low temperature fuel cells. Here we compare water and hydroxyl adsorption on Pt–Ni(111) films and a PtNi(111) alloy surface with the behaviour on the pure metals. Whereas water adsorbs and desorbs intact from close packed Pt and ...

Carbon nitride simultaneously boosted PtRu electrocatalyst’s stability and electrocatalytic activity toward concentrated methanol

12-Jun-2018 | Quan Zhang; Zehui Yang; Jun Yang; Xinxin Yu; Ying Ling; Yunfeng Zhang; Weiwei Cai; Hansong Cheng, Chemical Communication, 2018

Ruthenium dissolution is an inevitable issue for anodic electrocatalyst in direct methanol fuel cells (DMFCs). Carbon nitride (C3N4) decoration derived from carbonization of melamine simultaneously promoted PtRu electrocatalyst’s stability and electrocatalytic activity toward concentrated ...

First-Principles Description of Oxygen Self-Diffusion in Rutile TiO2: Assessment of Uncertainties due to Energy and Entropy Contributions

12-Jun-2018 | Heonjae Jeong; Edmund G Seebauer; Elif Ertekin, Physical Chemistry Chemical Physics, 2018

Properties related to transport such as self-diffusion coefficients are relevant to fuel cells, electrolysis cells, and chemical/gas sensors. Prediction of self-diffusion coefficients from first-principles involves precise determination of both enthalpy and entropy contributions for point defect ...
