Open circuit interaction of borohydride with oxidized platinum surfaces

Electrochemistry Communications, 2012
Abstract An interesting method to investigate the effect of fuel crossover in low temperature fuel cells consists of studying the open circuit interaction between the reducing fuel and an oxide-covered catalyst. Herein we report the experimental study of the open circuit interaction between borohydride and oxidized platinum surfaces in alkaline media.

Bimetallic Synergy in Cocatalyst Alloy Nanoparticles for Efficient Photocatalytic Hydrogen Production

EcoEnergy, EarlyView.
A bimetallic NiAg alloy is assembled on the surface of Zn3In2S6 to construct a NiAg‐Zn3In2S6 composite using a chemical reduction method. By adjusting the different alloy ratios, the hydrogen evolution activity of the optimum Ni0.25Ag0.75‐Zn3In2S6 photocatalyst achieves 21.32 mmol·g−1·h−1. ABSTRACT A bimetallic NiAg alloy is assembled on the surface of

Thermodynamic Mechanisms of Co‐S Bond Anchoring in Few‐Layered 1T‐MoS2 for Enhanced Capacitive Performance via Spin State Regulation and Ion Diffusion Kinetics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The one‐pot hydrothermal prep of Co‐doped few‐layer 1T‐MoS2 shows Co‐S bonds stabilizing the 1T phase, enhancing supercapacitor performance. Few‐layered 1T‐MoS2 is highly promising for supercapacitor applications due to its wide interlayer spacing, high electrical conductivity, and abundant active sites.
