In this work, an inexpensive electrocatalyst, Ni-doped Mo 2 C nanowires have been directly grown on Ni Foam via a hydrothermal reaction combined with carburization process. X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), and linear scanning 10 voltammetry (LSV) were used to scrutinize the catalysts and the electrochemical performance. The results show that the designed NiMo 2 C/NF catalyst displays enhanced catalytic activity toward hydrogen production with a low onset overpotential of 21 mV. For driving a cathodic current density of 100 mA cm -2 , it only needs overpotential of 150 mV. Such excellent performance of the NiMo 2 C/NF could be ascribed to the high intrinsic activity from a synergistic function of Ni and Mo 2 C, as well as the exposure of more Ni-doped Mo 2 C sites provided by the high aspect ratio of one-dimensional (1D) structure and rich surface area. 15

A large portion of world's natural gas reserves are "stranded" resources, the drive to monetize these resources leads to the development of gas-to-liquids (GTL) and liquefied natural gas (LNG) technologies. LNG has the advantage of having been developed for the past 40 years and having an excellent safety record. GTL on the other hand is another option with substantial benefits, but its development stage and commercial viability are far behind LNG. This paper presents a techno-economic comparison of GTL with LNG, including technical development, plant effi ciency, market potential for the products, and capital cost for the infrastructure. The aim is to give an overall view on both LNG and GTL and provide a perspective on the profi tability of these two technologies.
