The fabrication of a highly conductive ceria-embedded gadolinium-stabilized bismuth oxide nanocomposite solid electrolyte for low-temperature solid oxide fuel cells

Abstract

We report the synthesis of a nanocomposite solid electrolyte, (1 − x)Bi2O3–Gd2O3:xCeO2 (GDBC), made up of ceria-embedded gadolinium-stabilized bismuth oxide (Bi2O3–Gd2O3, GDB) for low-temperature solid oxide fuel cell (LT-SOFC) applications.

La/Fe bimetallic MOF-derived p-LaFeO3/n-CdS heterojunction: efficient photocatalytic degradation of organic contaminants and adsorption isotherms

“…Since the 15 LC heterojunction material contains a higher amount of CdS, the adsorption of dyes may also depend on the point of zero charge (pzc) of CdS and the earlier reports presented the point of zero charge of as-synthesized CdS. 58 As a result, at pH values below the pzc, the CdS particles would be positively charged and above this point, it would be negatively charged. From Fig.…”

Photoelectrochemical aptamer sensor based on AgInS2 and ZnS co-sensitized TiO2 for the detection of Hg2+

“…Silver indium sulfide (AgInS 2 ) is a kind of material with excellent photocatalytic performance because of its narrow band gap. 27,28 The chemical bonds of Ag-S and In-S are not equal, allowing an internal electric field to be generated so that AgInS 2 can be used as a catalyst. Unfortunately, AgInS 2 has the problem of fast recombination of photogenerated electrons and holes, which easily leads to unsatisfactory photoelectric performance.…”
