Aluminum electrodes undergo severe hydrogenation and self‐corrosion in alkaline solutions. Here, a novel inorganic‐organic hybrid corrosion inhibitor, constituted by Na2SnO3 and ethylene glycol, was formulated. Electrochemical tests demonstrated that the inhibitor could effectively suppress the self‐corrosion at the anode, increasing the anode utilization from ∼16 % to ∼43 % and the specific energy density from ∼543 to 1577 Wh kg−1. Moreover, a relatively stable discharge effect was observed. Based on surface morphology analysis, a mechanism for the deposition of Na2SnO3 and ethylene glycol on the surface of the aluminum electrode was proposed. It was suggested that the presence of ethylene glycol is conducive to a more uniform and denser deposition of tin on the surface of the aluminum electrode, a condition that can inhibit corrosion more efficiently as well as improve the discharge effect. The analysis of the entire adsorption energy using the Vienna ab initio simulation package supported this hypothesis.

The catalytic properties of hydrotalcite‐based Cu/Zn/Al mixed oxides prepared by the incipient co‐precipitation method, in which various metals were doped through impregnation, were comparatively tested in the steam reforming of methanol (SRM). In addition, the catalysts were characterized in detail by a series of follow‐up surface techniques. Moreover, strong interaction and synergism between Ru and Cu species noticeably promoted methanol conversion and improved catalytic performance. Furthermore, an SRM reaction mechanism is proposed that rationalizes the relationship between copper dispersion on the surface and the size of the copper/oxygen interface where formed intermediates rearrange.
