core-shelled Co 3 O 4-CoFe 2 O 4 heterojunction composites with the abundant …

A facile metal–organic framework (MOF)-derived isomeric strategy to prepare ZnO@ Co 3 O
4 single-shelled hollow cubes (HCs) is described. The crystallinity, morphology, and …

Designing high-activity electrocatalysts to enhance the slow multielectron-transfer process of
the oxygen evolution reaction (OER) is of great importance for hydrogen generation. Here …

In this article, a novel flower-like WO 3-In 2 O 3 hollow heterostructure was successfully
constructed by using an in situ etching method. The morphology characteristics revealed …

Gas sensors present significant research value and broad applicability for environmental
monitoring, medical diagnosis and agricultural production. As a p-type spinel ternary …

In the detection of food freshness and chemical production, live tracking of the concentration
of triethylamine gas is both essential and challenging. The NiCo 2 O 4-ZnO triethylamine …
