Geometric distortions in nickel (oxy)hydroxide electrocatalysts by redox inactive iron ions

03.07.2018 | Rodney D. L. Smith; Chiara Pasquini; Stefan Loos; Petko Chernev; Katharina Klingan; Paul Kubella; Mohammad Reza Moha ..., Energy & Environmental Science, 2018

The dramatic change in electrochemical behavior of nickel (oxy)hydroxide films upon incorporation of Fe ions provides an opportunity to establish effective electrocatalyst design principles. We characterize a photochemically deposited series of Fe–Ni (oxy)hydroxides by X-ray absorption ...

Facile in situ fabrication of oriented titania submicrorods embedded into a superelastic nickel-titanium alloy fiber substrate and their application in solid-phase microextraction

03.07.2018 | Feifei Wang; Zhuo Wang; Ziyi Wang; Rong Zhang; Junliang Du; Xin-zhen Du, New Journal of Chemistry, 2018

A nickel-titanium oxide (NiO/TiO2) coating was in situ grown on a nickel-titanium alloy (NiTi) fiber substrate by anodic oxidation. After annealing, a uniform and dense Ni-free coating of rutile phase TiO2 submicrorods (TiO2SRs) was formed. In particular, TiO2SRs were embedded into the NiTi fiber ...

High selectivity of CO2 hydrogenation to CO by controlling the valence state of nickel using perovskite

03.07.2018 | Baohuai Zhao; Binhang Yan; Zhao Jiang; Siyu Yao; Zongyuan Liu; Qiyuan Wu; Rui Ran; Sanjaya D. Senanayake; Duan Weng; ..., Chemical Communication, 2018

The selectivity of CO2 hydrogenation can be significantly tuned by controlling the valence state of nickel using lanthanum–iron–nickel perovskites. Nickel with higher valence states weakens the binding of CO and increases the activation barrier for further CO hydrogenation, leading to a higher CO ...

Selective CO2 reduction to C3 and C4 oxyhydrocarbons on nickel phosphides at overpotentials as low as 10 mV

26.06.2018 | Karin U. D. Calvinho; Anders B. Laursen; Kyra M. K. Yap; Timothy A. Goetjen; Shinjae Hwang; Bryan Mejia-Sosa; Alexan ..., Energy & Environmental Science, 2018

We introduce five nickel phosphide compounds as electro-catalysts for the reduction of carbon dioxide in aqueous solution, that achieve unprecedented selectivity to C3 and C4 products (the first such report). Three products: formic acid (C1), methylglyoxal (C3) and 2,3-furandiol (C4), are ...
